Paragraph (16)
When processing a Word document, you may need to remove some paragraphs. For example, after you copied contents from the Internet with a lot of redundant paragraphs to your document, you need to delete the extra paragraphs and keep only those that are useful. The deletion can be easily achieved by Spire.Doc for .NET by programming with no need for other software. This article will show you the detailed steps of removing paragraphs in a Word document using Spire.Doc for .NET.
Install Spire.Doc for .NET
To begin with, you need to add the DLL files included in the Spire.Doc for.NET package as references in your .NET project. The DLL files can be either downloaded from this link or installed via NuGet.

Delete a Specific Paragraph in a Word Document
Spire.Doc for .NET provides a method RemoveAt() under ParagraphCollection to remove paragraphs.
The detailed steps of removing a specific paragraph are as follows:
- Create an object of Document class.
- Load a Word document using Document.LoadFromFile() method.
- Get the first section using Document.Section[] property.
- Remove the 4th paragraph using Section.Paragraphs.RemoveAt() method.
- Save the document using Document.SaveToFile() method.
- C#
- VB.NET
using System;
using Spire.Doc;
namespace RemoveParagraphs
{
internal class Program
{
static void Main(string[] args)
{
//Create an object of Document class
Document document = new Document();
//Load a Word document
document.LoadFromFile("Sample.docx");
//Get the first section
Section section = document.Sections[0];
//Remove the first paragraph in the section
section.Paragraphs.RemoveAt(3);
//Save the document
document.SaveToFile("RemoveParagraphs.docx", FileFormat.Docx2013);
}
}
}
Delete All Paragraphs in a Word Document
To remove all paragraphs, you can use the method Clear() under ParagraphCollection provided by Spire.Doc for .NET.
The detailed steps are as follows:
- Create an object of Document class.
- Load a Word Document using Document.LoadFromFile() method.
- Loop through all sections, and remove all paragraphs in each section using Section.Paragraphs.Clear() method.
- Save the document using Document.SaveToFile() method.
- C#
- VB.NET
using System;
using Spire.Doc;
namespace RemoveAllParagraphs
{
internal class Program
{
static void Main(string[] args)
{
//Create an object of Document class
Document document = new Document();
//Load a Word document
document.LoadFromFile("Sample.docx");
//Loop through all sections
foreach (Section section in document.Sections)
{
//Remove all paragraphs in the section
section.Paragraphs.Clear();
}
//Save the document
document.SaveToFile("RemoveAllParagraphs.docx", FileFormat.Docx2013);
}
}
}

By using Spire.Doc, you can not only retrieve the style names of all paragraphs in a Word document, but also get the paragraphs with a specific style name. This is useful especially when you need to get the text in Title, Heading 1, Subtitle, etc.
| Paragraph Style Names in Word | Paragraph Style Names in Spire.Doc |
| Title | Title |
| Heading 1 | Heading1 |
| Heading 2 | Heading2 |
| Heading 3 | Heading3 |
| Heading 4 | Heading3 |
| Subtitle | Subtitle |
Step 1: Load a sample Word file when initializing the Document object.
Document doc = new Document("sample.docx");
Step 2: Traverse the sections and paragraphs in the document and determine if the paragraph style name is "Heading1", if so, write the paragraph text on screen.
foreach (Section section in doc.Sections)
{
foreach (Paragraph paragraph in section.Paragraphs)
{
if (paragraph.StyleName == "Heading1")
{
Console.WriteLine(paragraph.Text);
}
}
}

How to set the spacing before and after the paragraph in C#
2017-11-01 08:46:38 Written by support iceblueWith Spire.Doc, we can set the formats for paragraph in C#. This article will focus on demonstrate how to set the spacing before and after the paragraph in C#.
Set the spacing before and after the paragraph for a newly added paragraph added by the method of paragraph.AppendHTML() to a new blank word document.
//create a new word document and add a section and paragraph to it.
Document doc = new Document();
Section sec = doc.AddSection();
Paragraph para = sec.AddParagraph();
//Add the text strings to the paragraph and set the style
para.AppendHTML("Add a new paragraph to the word and set the spacing
");
para.ApplyStyle(BuiltinStyle.Heading1);
//set the spacing before and after
para.Format.BeforeAutoSpacing = false;
para.Format.BeforeSpacing = 20;
para.Format.AfterAutoSpacing = false;
para.Format.AfterSpacing = 20;
//save the document to file
doc.SaveToFile("Result1.docx");
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
namespace SetSpacing
{
class Program
{
static void Main(string[] args)
{
//create a new word document and load the sample from file
Document document = new Document();
document.LoadFromFile("sample.docx", FileFormat.Docx);
//Add the text strings to the paragraph and set the style
Paragraph para = new Paragraph(document);
TextRange textRange1 = para.AppendText("This is a inserted paragraph.");
textRange1.CharacterFormat.TextColor = Color.Blue;
textRange1.CharacterFormat.FontSize = 15;
//set the spacing before and after
para.Format.BeforeAutoSpacing = false;
para.Format.BeforeSpacing = 10;
para.Format.AfterAutoSpacing = false;
para.Format.AfterSpacing = 10;
//insert the added paragraph to the word document
document.Sections[0].Paragraphs.Insert(1, para);
//save the document to file
document.SaveToFile("Result2.docx", FileFormat.Docx2010);
}
}
}
Tab stops are markers placed on the ruler that define how text or numbers are aligned on a line. To add tab stops to a paragraph in Microsoft Word, we need to open the Tabs dialog box and then set the tab stop position, alignment and leader as shown below.
This article elaborates how to add tab stops to paragraphs in word document programmatically using Spire.Doc.
Detail steps:
Step 1: Instantiate a Document object and add a section to it.
Document document = new Document(); Section section = document.AddSection();
Step 2: Add paragraph 1 to the section.
Paragraph paragraph1 = section.AddParagraph();
Step 3: Add tab stops to paragraph 1.
//Add tab and set its position (in points)
Tab tab = paragraph1.Format.Tabs.AddTab(28);
//Set tab alignment
tab.Justification = TabJustification.Left;
//move to next tab and append text
paragraph1.AppendText("\tWashing Machine");
//Add another tab and set its position (in points)
tab = paragraph1.Format.Tabs.AddTab(280);
//Set tab alignment
tab.Justification = TabJustification.Left;
//Specify tab leader type
tab.TabLeader = TabLeader.Dotted;
//move to next tab and append text
paragraph1.AppendText("\t$650");
Step 4: Add paragraph 2 to the section.
Paragraph paragraph2 = section.AddParagraph();
Step 5: Add tab stops to paragraph 2.
//Add tab and set its position (in points)
tab = paragraph2.Format.Tabs.AddTab(28);
//Set tab alignment
tab.Justification = TabJustification.Left;
//move to next tab and append text
paragraph2.AppendText("\tRefrigerator");
//Add another tab and set its position (in points)
tab = paragraph2.Format.Tabs.AddTab(280);
//Set tab alignment
tab.Justification = TabJustification.Left;
//Specify tab leader type
tab.TabLeader = TabLeader.NoLeader;
//move to next tab and append text
paragraph2.AppendText("\t$800");
Step 6: Save and close the document object.
document.SaveToFile("Tab.docx", FileFormat.Docx2013);
document.Close();

//Add paragraph 1
Paragraph paragraph1 = section.AddParagraph();
//Add tab and set its position (in points)
Tab tab = paragraph1.Format.Tabs.AddTab(28);
//Set tab alignment
tab.Justification = TabJustification.Left;
//move to next tab and append text
paragraph1.AppendText("\tWashing Machine");
//Add another tab and set its position (in points)
tab = paragraph1.Format.Tabs.AddTab(280);
//Set tab alignment
tab.Justification = TabJustification.Left;
//Specify tab leader type
tab.TabLeader = TabLeader.Dotted;
//move to next tab and append text
paragraph1.AppendText("\t$650");
//Add paragraph 2
Paragraph paragraph2 = section.AddParagraph();
//Add tab and set its position (in points)
tab = paragraph2.Format.Tabs.AddTab(28);
//Set tab alignment
tab.Justification = TabJustification.Left;
//move to next tab and append text
paragraph2.AppendText("\tRefrigerator"); //move to next tab and append text
//Add another tab and set its position (in points)
tab = paragraph2.Format.Tabs.AddTab(280);
//Set tab alignment
tab.Justification = TabJustification.Left;
//Specify tab leader type
tab.TabLeader = TabLeader.NoLeader;
//move to next tab and append text
paragraph2.AppendText("\t$800");
//Save and close the document object
document.SaveToFile("Tab.docx", FileFormat.Docx2013);
document.Close();
}
}
}

When we want to manage the pagination for the paragraphs, we can insert a page break directly. But later we may find that it is hard to add or remove text above the page break and then we have to remove the whole page break. With Microsoft word, we can also use the Paragraph dialog to manage the pagination flexible for the word paragraph as below:
We have already shown you how to insert page break to the word document, this article we will show you how to manage the pagination by using the Paragraph.Format offered by Spire.Doc. Here comes to the steps of how to manage the pagination for the word document paragraph in C#:
Step 1: Create a new word document and load the document from file.
Document doc = new Document();
doc.LoadFromFile("sample.docx");
Step 2: Get the first section and the paragraph we want to manage the pagination
Section sec = doc.Sections[0]; Paragraph para = sec.Paragraphs[4];
Step 3: Set the pagination format as Format.PageBreakBefore for the checked paragraph.
para.Format.PageBreakBefore = true;
Step 4: Save the document to file.
doc.SaveToFile("result.docx",FileFormat.Docx2010);
Effective screenshot after managing the pagination for the word document:
Full codes:
using Spire.Doc;
using Spire.Doc.Documents;
namespace ManagePage
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
doc.LoadFromFile("sample.docx");
Section sec = doc.Sections[0];
Paragraph para = sec.Paragraphs[4];
para.Format.PageBreakBefore = true;
doc.SaveToFile("result.docx", FileFormat.Docx2010);
}
}
}
When we operate the word document, we can hide some texts or the whole paragraph on the Microsoft Word after click the font box to hide the selected texts. Please check the screenshot of how Microsoft hide the text as below:
Spire.Doc offers a CharacterFormat.Hidden property to enable developers to hide the specified text or the whole paragraph. This article will demonstrate how to hide the whole paragraph on the word document in C#.
Here comes to the code snippets:
Step 1: Create a new word document and load from file.
Document doc = new Document();
doc.LoadFromFile("sample.docx");
Step 2: Get the first section and the first paragraph from the word document.
Section sec = doc.Sections[0]; Paragraph para = sec.Paragraphs[0];
Step 3: Get the first TextRange and set CharacterFormat.Hidden property as true to hide the texts.
(para.ChildObjects[0] as TextRange).CharacterFormat.Hidden = true;
Step 4: Save the document to file.
doc.SaveToFile("result.docx", FileFormat.Docx);
Effective screenshot after the paragraph is hidden:
After we set the options to display the hidden text, the hidden text will show like this:
Full codes:
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
namespace HideParagh
{
class Program
{
static void Main(string[] args)
{

doc.LoadFromFile("sample.docx");
Section sec = doc.Sections[0];
Paragraph para = sec.Paragraphs[0];
(para.ChildObjects[0] as TextRange).CharacterFormat.Hidden = true;
doc.SaveToFile("result.docx", FileFormat.Docx);
}
}
}
With the help of Spire.Doc, developers can easily merge multiple word documents into one word documents. After merged the documents, you may need to insert a note or new paragraph to add some description on it. This article explains and describes how to insert a new paragraph to the existing word document in C# by using Spire.Doc.
The following example shows how to insert a paragraph into the document.
Step 1: Create a new document and load from file.

Step 2: Create a new document and add new section.
Document doc2 = new Document(); doc2.AddSection();
Step 3: Create new paragraph p and set its property of TextAlignment as "Center".
p.AppendText("Alignment:Center ");
p.AppendHTML(File.ReadAllText(@"test.html"));
p.Format.TextAlignment = TextAlignment.Center;
Step 4: Set other options to make a contrast, Auto is Baseline by default.
Paragraph p1 = doc2.Sections[0].AddParagraph();
p1.AppendText("Alignment:Baseline ");
p1.AppendHTML(File.ReadAllText(@"test.html"));
p1.Format.TextAlignment = TextAlignment.Baseline;
Paragraph p2 = doc2.Sections[0].AddParagraph();
p2.AppendText("Alignment:Bottom ");
p2.AppendHTML(File.ReadAllText(@"test.html"));
p2.Format.TextAlignment = TextAlignment.Bottom;
Paragraph p3 = doc2.Sections[0].AddParagraph();
p3.AppendText("Alignment:Top ");
p3.AppendHTML(File.ReadAllText(@"test.html"));
p3.Format.TextAlignment = TextAlignment.Top;
Paragraph p4 = doc2.Sections[0].AddParagraph();
p4.AppendText("Alignment:Auto ");
p4.AppendHTML(File.ReadAllText(@"test.html"));
p4.Format.TextAlignment = TextAlignment.Auto;
Step 5: Save and review.
doc2.SaveToFile(@"test.doc", FileFormat.Doc);
System.Diagnostics.Process.Start("test.doc");
