问题 Suppose I have sample Upload file method like this in POStFile.aspx . This method POST file (upload file) to http WEBDAV url. public static void HttpUploadFile(string url, string file, string paramName, string contentType, NameValueCollection nvc) { log.Debug(string.Format("Uploading {0} to {1}", file, url)); string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x"); byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");
