Hey, I've got this nice little piece of code, much like all the other versions of this method of upload using WSS WebServices. I've got one major problem though - once I have uploaded a file into my doc list, and updated the list item to write a comment/description, the file is stuck there. What I mean is that this method will not overwrite the file once I've uploaded it. Nobody else out there seems to have posted this issue yet, so .. anyone?
I have another version of the method which uses a byte[] instead of a Stream .. same issue though.
Note: I have switched off the 'require documents to be checked out before they can be edited' option for the library. No luck tho .. The doc library does have versioning turned on though, with a major version being created for each update.
private void UploadStream(string fullPath, Stream uploadStream)
{
WebRequest request = WebRequest.Create(fullPath);
request.Credentials = CredentialCache.DefaultCredentials; // User must have 'Contributor' access to the document library
request.Method = "PUT";
request.Headers.Add("Overwrite", "t");
byte[] buffer = new byte[4096];
using (Stream stream = request.GetRequestStream())
{
for (int i = uploadStream.Read(buffer, 0, buffer.Length); i > 0; i = uploadStream.Read(buffer, 0, buffer.Length))
{
stream.Write(buffer, 0, i);
}
}
WebResponse response = request.GetResponse(); // Upload the file
response.Close();
}

EDIT -- major finding .. when I call it from my nUnit test project it works fine. It seems it only fails when I call it from my WCF application (nUnit running under logged on user account, WCF app has app pool running under that same user -- my account, which also has valid permissions in SharePoint).
Nuts. "Now where to start?!", I muses to myself.
