Hi Bollineni,

Thanks for posting in the MSDN forum.

I would recommend you try following snippet:

using (WordprocessingDocument myDoc =
    WordprocessingDocument.Open("Test1.docx", true))
{
    string altChunkId = "AltChunkId1";
    MainDocumentPart mainPart = myDoc.MainDocumentPart;
    AlternativeFormatImportPart chunk = mainPart.AddAlternativeFormatImportPart(
        AlternativeFormatImportPartType.WordprocessingML, altChunkId);
    using (FileStream fileStream = File.Open("TestInsertedContent.docx", FileMode.Open))
        chunk.FeedData(fileStream);
    AltChunk altChunk = new AltChunk();
    altChunk.Id = altChunkId;
    mainPart.Document
        .Body
        .InsertAfter(altChunk, mainPart.Document.Body.Elements<Paragraph>().Last());
    mainPart.Document.Save();
}

Have a good day,

Tom

You can try using this toolkit. It is basically a document generation toolkit/library for .NET but it is also very capable at merging documents. It doesn't use the altChunk technique but instead "really merges" sub documents into a mester document. This is a much better approach for two reasons: 1) a generated document can be also open in a non MS Word apps (like Open Office) which do not support altChunks and 2) you are not constrained to insert sub-documents at the root of the master document but can also insert it into e.g. a table cell or a middle of a paragraph. The minus is that the toolkit is a commercial product and it will cost you some money.
