How to delete a specific range of content in a Word document

3 mins read

Syncfusion Essential DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can delete a specific range of content in a Word document using C#.

Steps to delete a specific range of content in a Word document:

Create a new .NET Core console application project.
Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your project from NuGet.org.

Starting with v16.2.0.x, if you reference Syncfusion assemblies from trial setup or from the NuGet feed, include a license key in your projects. Refer to the link to learn about generating and registering a Syncfusion license key in your application to use the components without trail message.

Include the following namespaces in Program.cs file
C#

using Syncfusion.DocIO.DLS;
using Syncfusion.DocIO;

Use the following code example to delete a specific range of content in a Word document.
C#

using (FileStream inputFileStream = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.Read))
{
   // Opens the template Word docuemnt.
   using (WordDocument document = new WordDocument(inputFileStream, FormatType.Docx))
   {
       // Deletes content from the 2nd to the 6th index in the text body of the Word document.
       DeleteSpecificContent(2, 6, document);
       using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           // Saves the modified Word document to the output file stream.
           document.Save(outputFileStream, FormatType.Docx);
       }
   }
}

Use the following helper method to delete content from the specified start index to the end index within the text body of the Word document…
C#

/// <summary>
/// Deletes content from the specified start index to the end index within the text body of the Word document.
/// </summary>
void DeleteSpecificContent(int startIndex, int endIndex, WordDocument document)
{
   // Retrieves the text body of the last section in the Word document.
   WTextBody body = document.LastSection.Body;
   // Ensures the start and end indices are within valid bounds.
   if (startIndex >= 0 && endIndex < body.ChildEntities.Count && startIndex <= endIndex)
   {
       // Removes items from endIndex to startIndex in reverse order to prevent index shifting issues.
       for (int index = endIndex; index >= startIndex; index--)
       {
           body.ChildEntities.RemoveAt(index);
       }
   }
}

You can download a complete working sample to delete a specific range of content in a Word document from the GitHub.

By executing the program, you will get the Word document as follows.

Take a moment to peruse the documentation where you can find basic Word document processing options along with the features like mail merge, merge, split, and compare Word documents, find and replace text in the Word document, protect the Word documents, and most importantly, the PDF and Image conversions with code examples.
