4 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 merge multiple Word documents into a same page in a Word document using C#.

Steps to merge multiple Word documents into a same page 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; 
using Syncfusion.DocIO.DLS;

Use the following code example to merge multiple Word documents into a same page in a Word document.
C#

//Create a list and add the paths of the source Word documents to it.
List<string> sourceFileNames = new List<string>();
sourceFileNames.Add("Data/Addressblock.docx");
sourceFileNames.Add("Data/Salutation.docx");
sourceFileNames.Add("Data/Greetings.docx");

//Get the absolute path of the destination Word document.
string destinationFileName = Path.GetFullPath(@"Data/Title.docx");
using (FileStream destinationStream = new FileStream(destinationFileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
   //Open the destination document.
   using (WordDocument destinationDocument = new WordDocument(destinationStream, FormatType.Automatic))
   {
       ImportOtherDocuments(sourceFileNames, destinationDocument);
       //Save the destination document.
       using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Output.docx"), FileMode.Create, FileAccess.Write))
       {
           destinationDocument.Save(outputStream, FormatType.Docx);
       }
   }
}

Use the following helper method to import content from multiple source Word documents into a destination document.
C#

/// <summary>
/// Import content from multiple source Word documents into a destination document.
/// </summary>
void ImportOtherDocuments(List<string> sourceFiles, WordDocument destinationDocument)
{
   //Iterate through each source document from the list.
   foreach (string sourceFileName in sourceFiles)
   {
       using (FileStream sourceStream = new FileStream(sourceFileName, FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
       {
           //Open the source document.
           using (WordDocument sourceDocument = new WordDocument(sourceStream, FormatType.Automatic))
           {
               //Set the break-code of First section of source document as NoBreak to avoid imported from a new page.
               sourceDocument.Sections[0].BreakCode = SectionBreakCode.NoBreak;
               //Import the contents of source document at the end of destination document.
               destinationDocument.ImportContent(sourceDocument, ImportOptions.UseDestinationStyles);
           }
       }
   }
}
