Helper Code for uploading a document to a SharePoint document library.

In one my projects we had a requirement to programmatically upload document to a SharePoint’s document library.

Below is the code we used to achieve that.

        // documentFileUrl would be :- http://server_name/doclibraryname/foldername (till doclibrary name or folder name to which doc
		// is to be uploaded
		// bytes :- byte array of the content
		// fileNameWithExtension would be :- test.docx
		// listName :- the display name of the list

	   public void UploadDoctofolder(string docfileurl, string fileNameWithExtension, byte[] bytes, string listName)
        {
            WebRequest request = WebRequest.Create(docfileurl + "/" + fileNameWithExtension);
            request.Credentials = this.credentials;
            request.Method = "PUT";

            byte[] buffer = new byte[1024];
            using (Stream stream = request.GetRequestStream())
            {
                using (MemoryStream ms = new MemoryStream(bytes))
                {
                    for (int i = ms.Read(buffer, 0, buffer.Length); i > 0; i = ms.Read(buffer, 0, buffer.Length))
                    {
                        stream.Write(buffer, 0, i);
                    }
                }
            }

            WebResponse response = request.GetResponse();
            response.Close();
        }

Hope it helps!
