How to merge one document to another with the margins of destination document?

Syncfusion Essential DocIO is a .NET Core Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can merge one document to another with the margins  of the destination document using C#.

Steps to merge one document to another with the margins of the destination document using C#:

1. Create a new C# .NET Core console application project.
2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your .NET Core applications from NuGet.org.
3. Include the following namespace in the Program.cs file:

C#

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

4. Use the following code example to merge one document to another with the margins of the destination document using C#:

C#

//Open the file as a stream.
using (FileStream sourceStreamPath = new FileStream(Path.GetFullPath(@"../../../Data/SourceDocument.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
    //Load the file stream into a Word document.
    using (WordDocument sourceDocument = new WordDocument(sourceStreamPath, FormatType.Automatic))
    {
        using (FileStream destinationStreamPath = new FileStream(Path.GetFullPath(@"../../../Data/DestinationDocument.docx"), FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
        {
            //Open the destination document.
            using (WordDocument destinationDocument = new WordDocument(destinationStreamPath, FormatType.Automatic))
            {
                //Get the page setup of the destination document.
                WPageSetup destinationDocumentPageSetup = destinationDocument.LastSection.PageSetup;
                //Iterate source document.
                foreach (WSection sourceSection in sourceDocument.Sections)
                {
                    sourceSection.PageSetup.Margins = destinationDocumentPageSetup.Margins;
                    //Clone and merge the source document sections to the destination document.
                    destinationDocument.Sections.Add(sourceSection.Clone());
                }
                //Create a file stream.
                using (FileStream outputFileStream = new FileStream(Path.GetFullPath(@"../../../Sample.docx"), FileMode.Create, FileAccess.ReadWrite))
                {
                    //Save the Word document to the file stream.
                    destinationDocument.Save(outputFileStream, FormatType.Docx);
                }
            }
        }
    }
}
