                   试试

               b如果(response.StatusCode.ToString()！=确定")
              nbsp; bsp    cls.SendEmail(上传文件满载失败"，文件的上传" + strURLFullfill +"失败:状态为"+ response.StatusCode + quot ;:"

                    //if (intSuccess == 200)
                    //    File.Delete(PATH + "Output\\" + flInfo.Name + ".xml");
                    //else
                    //    SendEmail("VitaminShield Upload Fullfill file failure", "Uploading of " + flInfo.Name + ".xml failed: Error Code " + intSuccess.ToString());

                    try
                    {
                        wc2.UploadFile(strURLFullfill, strFile);
                        responseField = wc2.GetType().GetField("m_WebResponse", BindingFlags.Instance | BindingFlags.NonPublic);
                        response = responseField.GetValue(wc2) as HttpWebResponse;

                        if (response.StatusCode.ToString() != "OK")
                            cls.SendEmail("Upload Fullfill file failure", "Uploading of " + strURLFullfill + " failed: Status " + response.StatusCode + ": "
                                    + response.StatusDescription);

                        File.Delete(strURLFullfill);
                    }
                    catch (Exception ex)
                    {
                        cls.SendEmail("Upload/Delete Fullfill file failure", "Uploading/Deleting of " + strURLFullfill + " failed: " + ex.Message);
                    }
                    finally
                    {
                        wc2.Dispose();
                    }

这是对以下陈述的夸大: b wc2.UploadFile(strURLFullfill，strFile);

This is blowing up on the following statement: wc2.UploadFile(strURLFullfill, strFile);

请让我知道为什么.
