项目运用中的FTP上传实现

入口程序：

string IP = System.Configuration.ConfigurationManager.AppSettings["IP"].ToString();
string UName = System.Configuration.ConfigurationManager.AppSettings["UserName"].ToString();
string PWD = System.Configuration.ConfigurationManager.AppSettings["PWD"].ToString();
FTPClient.FtpHelper ftpHelper = new FtpHelper(IP,UName,PWD);//入口

int count =Convert.ToInt32( System.Configuration.ConfigurationManager.AppSettings["count"]); //ftp上传重试次数
string ftpPath = System.Configuration.ConfigurationManager.AppSettings["ftpPath"].ToString();
//日志记录
Assist.Log.VisitLog.WriteLog(DateTime.Now.ToString() + "开始上传Android包 id=" + intMagID.ToString());
bool Android= ftpHelper.TryUpload(AppDomain.CurrentDomain.BaseDirectory+ @"OutPut\" + intMagID + "\\ad15_" + intMagID + ".apk", ftpPath+"\\"+ intMagID,count);
　　　　　　　　　　　　　　　　　　　　　　　　　　　　//string filename, string FTPPath, int count
　　if (Android == false)
  　　{                 
　　　　Assist.Log.VisitLog.WriteLog(DateTime.Now.ToString() + "上传Android包失败 id=" + intMagID.ToString());
  　　}
　　else
     {   
       Assist.Log.VisitLog.WriteLog(DateTime.Now.ToString() + "上传Android包成功 id=" + intMagID.ToString());
     }
