使用MemoryStream在远程位置C＃上写入.docx文件

Question

I am generating MemoryStream from string and pass it to another method which will save that Stream at remote loaction in form of .docx file.

public static MemoryStream GenerateStreamFromString(string s)
{
    MemoryStream stream = new MemoryStream();
    StreamWriter writer = new StreamWriter(stream);
    writer.Write(s);
    writer.Flush();
    stream.Position = 0;
    return stream;
}

Above code is for convert the string to MemoryStream. The string I am passing to the above method is XML which I get by Globals.ThisAddIn.Application.ActiveDocument.WordOpenXML line.

File successfully get uploaded to remote location but as I download that file, MS Word throws an error that File is corrupted. Either part of file is missing or invalid File is corrupted. Either part of file is missing or invalid (As shown in below image)

I am not able to get that whether the Stream I am generating is wrong/corrupted or I need to perform some more operation to make this .docx file valid?

Sorry for this question, there are so many questions like this, but none could be more helpful.

Answer 1

The XML passed this way is not a valid DOCX file. The actual DOCX format uses compressed content with folders. You need to save the document from your add in to a temporary location (best use GetTempPath , then read the file from disk into your memory stream and upload it wherever you need.
