好的，我不知道为什么这不起作用。相同的代码仅适用于上传元数据，然后适用于多部分上传。我无法恢复上传工作。

上传文件 说第 1 步应该返回一个带有 upload_id 的 200 ok 但是下面的行没有返回任何内容。内容长度为 0 没有错误响应 什么都没有。 

string responseFromServer = reader.ReadToEnd();

我的代码：

FileInfo info = new FileInfo(pFilename);
String MimeType = GetMimeType(pFilename).ToString();
string footer = "\r\n";
//Createing the MetaData to send
List<string> _postData = new List<string>();
_postData.Add("{");
_postData.Add("\"title\": \"" + info.Name + "\"");
_postData.Add("}");
string postData = string.Join(" ", _postData.ToArray());
byte[] MetaDataByteArray = Encoding.UTF8.GetBytes(postData);
// creating the Data For the file
byte[] FileByteArray = System.IO.File.ReadAllBytes(pFilename);

string url = "https://www.googleapis.com/upload/drive/v2/files?uploadType=resumable";
int headerLenght =  MetaDataByteArray.Length  +footer.Length;

WebRequest request = WebRequest.Create(url);
request.Method = "POST";
request.Headers.Add("Authorization", string.Format("Bearer {0}", myAutentication.accessToken));
request.ContentLength = headerLenght;
request.ContentType = "application/json; charset=UTF-8";
request.Headers.Add("X-Upload-Content-Type", MimeType);
request.Headers.Add("X-Upload-Content-Length", FileByteArray.Length.ToString());           

Stream dataStream = request.GetRequestStream();
dataStream.Write(MetaDataByteArray, 0, MetaDataByteArray.Length); // write the MetaData 
        dataStream.Write(Encoding.UTF8.GetBytes(footer), 0, Encoding.UTF8.GetByteCount(footer));  // done writeing add return just 
        dataStream.Close();

  try
      {
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();


            Console.WriteLine(((HttpWebResponse)response).StatusDescription);
            // Display the status.  IT returns OK 


            // Get the stream containing content returned by the server.
            dataStream = response.GetResponseStream();

            // Open the stream using a StreamReader for easy access.
            StreamReader reader = new StreamReader(dataStream);

            // Read the content.
            string responseFromServer = reader.ReadToEnd();

            // Display the content.  ResponseFromServer returns "" nothing.  
            //Console.WriteLine(responseFromServer);
            // Clean up the streams.
            reader.Close();
            dataStream.Close();
            response.Close();
}
catch (Exception ex)
        {
            return "Exception uploading file: uploading file." + ex.Message;
            //return Error.CreateJsonError("HttpWeb.Post", "1", "Error: " + ex.Message);
        }

我终于想通了。上传 ID 在响应标头中返回。 

WebResponse response = request.GetResponse();
string Location = response.Headers["Location"];
