- Create a Document object.
- Load a Word document using the Document.LoadFromFile() method.
- Get the body of the last section of the document using Document.LastSection.Body.
- Add a page break by calling Paragraph.AppendBreak(BreakType.PageBreak) method.
- Create a new ParagraphStyle object.
- Add the new paragraph style to the document's style collection using Document.Styles.Add() method.
- Create a new Paragraph object and set the text content.
- Apply the previously created paragraph style to the new paragraph using Paragraph.ApplyStyle(ParagraphStyle.Name) method.
- Add the new paragraph to the document using Body.ChildObjects.Add(Paragraph) method.
- Save the resulting document using the Document.SaveToFile() method.
- C#
// Create a new document object
Document document = new Document();
// Load a document
document.LoadFromFile("Sample.docx");
// Get the body of the last section of the document
Body body = document.LastSection.Body;
// Insert a page break after the last paragraph in the body
body.LastParagraph.AppendBreak(BreakType.PageBreak);
// Create a new paragraph style
ParagraphStyle paragraphStyle = new ParagraphStyle(document);
paragraphStyle.Name = "CustomParagraphStyle1";
paragraphStyle.ParagraphFormat.LineSpacing = 12;
paragraphStyle.ParagraphFormat.AfterSpacing = 8;
paragraphStyle.CharacterFormat.FontName = "Microsoft YaHei";
paragraphStyle.CharacterFormat.FontSize = 12;
// Add the paragraph style to the document's style collection
document.Styles.Add(paragraphStyle);
// Create a new paragraph and set the text content
Paragraph paragraph = new Paragraph(document);
paragraph.AppendText("Thank you for using our Spire.Doc for .NET product. The trial version will add a red watermark to the generated document and only supports converting the first 10 pages to other formats.

// Add a table
Table tableCaption = section.AddTable(true);
tableCaption.ResetCells(3, 2);
// Add a caption to the table
tableCaption.AddCaption("Table", CaptionNumberingFormat.Number, CaptionPosition.BelowItem);
// Add another table and caption
tableCaption = section.AddTable(true);
tableCaption.ResetCells(2, 3);
tableCaption.AddCaption("Table", CaptionNumberingFormat.Number, CaptionPosition.BelowItem);
// Update all fields in the document
document.IsUpdateFields = true;
// Save to a docx document
string result = "AddTableCaption.docx";

document.LoadFromFile("Data/Sample.docx");
Section section;
// Iterate through all sections
for (int i = 0; i < document.Sections.Count; i++)
{
section = document.Sections[i];
// Iterate through paragraphs in reverse order
for (int j = section.Body.Paragraphs.Count - 1; j >= 0; j--)
{
// Check if the paragraph is a caption paragraph
if (DetectCaptionParagraph(section.Body.Paragraphs[j]))
{
// If it's a caption paragraph, remove it
section.Body.Paragraphs.RemoveAt(j);
}
}
}
// Save the document after removing captions
string result = "RemoveCaptions.docx";
document.SaveToFile(result, Spire.Doc.FileFormat.Docx2016);
// Close and dispose of the document object to release resources
document.Close();
document.Dispose();
}
// Method to detect if a paragraph is a caption paragraph
static bool DetectCaptionParagraph(Paragraph paragraph)
{
bool tag = false;
Field field;
// Iterate through the child objects in the paragraph
for (int i = 0; i < paragraph.ChildObjects.Count; i++)
{
if (paragraph.ChildObjects[i].DocumentObjectType == DocumentObjectType.Field)
{
// Check if the child object is of Field type
field = (Field)paragraph.ChildObjects[i];
if (field.Type == FieldType.FieldSequence)
{
// Check if the Field type is FieldSequence, indicating a caption field type
return true;
}
}
}
return tag;
}
