How to Unlink All Fields in a .Net Core Word document?

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 unlink all fields in a Word document using C#.

Steps to unlink all fields in a Word document:

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

3. Include the following namespaces in the Program.cs file.
   C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.DocIORenderer;
using System.Collections.Generic;

4. Use the following code example to unlink all fields in a Word document.
   C#

// Open the template Word document.
using (FileStream fileStream = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.ReadWrite))
{
   //Loads an existing Word document into DocIO instance.
   using (WordDocument document = new WordDocument(fileStream, FormatType.Automatic))
   {
       //Updates the fields present in a document
       document.UpdateDocumentFields(true);
       //Get all fields present in a document.
       List<Entity> fields = document.FindAllItemsByProperty(EntityType.Field, null, null);
       //Unlink all the fields.
       for (int i = 0; i < fields.Count; i++)
       {
           WField field = (WField)fields[i];
           if (field.Owner != null)
               field.Unlink();
       }
       //Creates file stream.
       using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
       {
           //Saves the Word document to file stream.
           document.Save(outputStream, FormatType.Docx);
       }
   }
}

You can download a complete working sample to unlink all fields in a Word document from GitHub.
