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 insert the content of a Word document into a block content control using C#.

Steps to insert the content of a Word document into a block content control:

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

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

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

4. Use the following code example to insert the content of a Word document into a block content control.
   C#

// Creates a new Word document.
using (WordDocument document = new WordDocument())
{
   // Adds new section to the document.
   IWSection section = document.AddSection();
   WTextBody textBody = section.Body;
   // Adds block content control into Word document.
   BlockContentControl blockContentControl = textBody.AddBlockContentControl(ContentControlType.RichText) as BlockContentControl;
   using (FileStream docStream = new FileStream(Path.GetFullPath(@"Data/Template.docx"), FileMode.Open, FileAccess.Read))
   {
       // Open the template Word document.
       using (WordDocument docxDocument = new WordDocument(docStream, FormatType.Docx))
       {
           // Insert the Word document into block content control.
           InsertContentIntoBlockContentControl(blockContentControl, docxDocument);
           using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"Output/Result.docx"), FileMode.Create, FileAccess.ReadWrite))
           {
               // Saves the Word document.
               document.Save(outputFileStream, FormatType.Docx);
           }
       }
   }
}

5. Use the following helper method to insert the content of a specified Word document into a block content control.
   C#

/// <summary>
/// Inserts the content of a specified Word document into a block content control.
/// </summary>
void InsertContentIntoBlockContentControl(BlockContentControl blockContentControl, WordDocument document)
{
   // Get the textbody of the another Word document and add it to the block content control.
   WTextBody textBody = document.LastSection.Body;
   foreach (IEntity entity in textBody.ChildEntities)
   {
       blockContentControl.TextBody.ChildEntities.Add(entity.Clone());
   }
}
