C#/VB.NET: Remove Hyperlinks in Word Documents
Hyperlinks in Word documents are clickable links that allow readers to navigate to a website or another document. While hyperlinks can provide valuable supplemental information, sometimes they can also be distracting or unnecessarily annoying, so you may want to remove them. In this article, you will learn how to remove hyperlinks from a Word document in C# and VB.NET 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.

Remove All the Hyperlinks in a Word Document
To delete all hyperlinks in a Word document at once, you'll need to find all the hyperlinks in the document and then create a custom method FlattenHyperlinks() to flatten them. The following are the detailed steps.
- Create a Document object.
- Load a sample Word document using Document.LoadFromFile() method.
- Find all the hyperlinks in the document using custom method FindAllHyperlinks().
- Loop through the hyperlinks and flatten all of them using custom method FlattenHyperlinks().
- Save the result document using Document.SaveToFile() method.
- C#
- VB.NET

Change the color or remove underline from hyperlink in Word with C#
By default, hyperlink in Word shows up as blue and underlined. In some cases, users may want to modify the hyperlink style so as to get better looking with the whole document. This article is going to introduce how we can remove the underline or change the color of hyperlinks using Spire.Doc in C#.
Code Snippets:
Step 1: Create a new object of Document class, add a section to it.
Document document = new Document(); Section section = document.AddSection();
Step 2: Add a paragraph and append a hyperlink to the paragraph. In order to format the hyperlink, we return the value of hyperlink in a TextRange.
Paragraph para= section.AddParagraph();
TextRange txtRange = para1.AppendHyperlink("www.e-iceblue.com", "www.e-iceblue.com", HyperlinkType.WebLink);
Step 3: Format the hyperlink with the specified the font name, font size, color and underline style.
txtRange.CharacterFormat.FontName = "Times New Roman"; txtRange.CharacterFormat.FontSize = 12; txtRange.CharacterFormat.TextColor = System.Drawing.Color.Red; txtRange.CharacterFormat.UnderlineStyle = UnderlineStyle.None;
Step 4: Save the file.
document.SaveToFile("result.docx", FileFormat.Docx2013);
Output:

Add Hyperlinks to Existing Text in Word
Adding hyperlinks to existing text in a document is a bit more complicated. You’ll need to find the target string first, and then replace it in the paragraph with a hyperlink field. The following are the steps.
- Create a Document object.
- Load a Word file using Document.LoadFromFile() method.
- Find all the occurrences of the target string in the document using Document.FindAllString() method, and get the specific one by its index from the collection.
- Get the string’s own paragraph and its position in it.
- Remove the string from the paragraph.
- Create a hyperlink field and insert it to position where the string is located.
- Save the document to another file using Document.SaveToFle() method.
- C#
- VB.NET
using Spire.Doc;
using Spire.Doc.Documents;
using Spire.Doc.Fields;
using Spire.Doc.Interface;
namespace AddHyperlinksToExistingText
{
class Program
{
static void Main(string[] args)
{
//Create a Document object
Document document = new Document();
//Load a Word file
document.LoadFromFile(@"C:\Users\Administrator\Desktop\sample.docx");
//Find all the occurrences of the string ".NET Framework" in the document
TextSelection[] selections = document.FindAllString(".NET Framework", true, true);
//Get the second occurrence
TextRange range = selections[1].GetAsOneRange();
//Get its owner paragraph
Paragraph parapgraph = range.OwnerParagraph;
//Get its position in the paragraph
int index = parapgraph.Items.IndexOf(range);
//Remove it from the paragraph
parapgraph.Items.Remove(range);
//Create a hyperlink field
Spire.Doc.Fields.Field field = new Spire.Doc.Fields.Field(document);
field.Type = Spire.Doc.FieldType.FieldHyperlink;
Hyperlink hyperlink = new Hyperlink(field);
hyperlink.Type = HyperlinkType.WebLink;
hyperlink.Uri = "https://en.wikipedia.org/wiki/.NET_Framework";
parapgraph.Items.Insert(index, field);
//Insert a field mark "start" to the paragraph
IParagraphBase start = document.CreateParagraphItem(ParagraphItemType.FieldMark);
(start as FieldMark).Type = FieldMarkType.FieldSeparator;
parapgraph.Items.Insert(index + 1, start);
//Insert a text range between two field marks
ITextRange textRange = new Spire.Doc.Fields.TextRange(document);
textRange.Text = ".NET Framework";
textRange.CharacterFormat.Font = range.CharacterFormat.Font;
textRange.CharacterFormat.TextColor = System.Drawing.Color.Blue;
textRange.CharacterFormat.UnderlineStyle = UnderlineStyle.Single;
parapgraph.Items.Insert(index + 2, textRange);
//Insert a field mark "end" to the paragraph
IParagraphBase end = document.CreateParagraphItem(ParagraphItemType.FieldMark);
(end as FieldMark).Type = FieldMarkType.FieldEnd;
parapgraph.Items.Insert(index + 3, end);
//Save to file
document.SaveToFile("AddHyperlink.docx", Spire.Doc.FileFormat.Docx);
}
}
