使用主页上面的课程

Using the above class in main page

 NetworkCredential NCredentials = new NetworkCredential(ConfigurationManager.AppSettings["Username"], ConfigurationManager.AppSettings["Password"]);

 using (new NetworkConnection(@"" + ConfigurationManager.AppSettings["Networkpath"].ToString(), NCredentials))
                        {
                       
  if (Directory.Exists(FPath + monthName))
                            {
                                FPath = FPath + monthName + "\\" + FileName;
                                FileStream fs = new FileStream(FPath, FileMode.Create);
                                fs.Write(results, 0, results.Length);
                                fs.Close();
                            }
                            else
                            {

                                Directory.CreateDirectory(FPath + monthName);
                                FPath = FPath + monthName + "\\" + FileName;
                                FileStream fs = new FileStream(FPath, FileMode.Create);
                                fs.Write(results, 0, results.Length);
                                fs.Close();
                            }
