一、建立连接

        public string connectFTP(string vPath, string vUID, string vPassword)         {             string errormsg = "";            Process proc = new Process();             try             {                 proc.StartInfo.FileName = "cmd.exe";                 proc.StartInfo.UseShellExecute = false;                 proc.StartInfo.RedirectStandardInput = true;                 proc.StartInfo.RedirectStandardOutput = true;                 proc.StartInfo.RedirectStandardError = true;                 proc.StartInfo.CreateNoWindow = true;                 proc.Start();                 string dosLine = "net use " + vPath + " " + vPassword + " /user:" + vUID;                 proc.StandardInput.WriteLine(dosLine);                 proc.StandardInput.WriteLine("exit");                 while (!proc.HasExited)                 {                     proc.WaitForExit(1000);                 }                 errormsg = proc.StandardError.ReadToEnd();                 proc.StandardError.Close();             }             catch (Exception ex)             {                 //throw ex;                 //MessageBox.Show(ex.Message);             }             finally             {                 proc.Close();                 proc.Dispose();             }             return errormsg;         }

二、上传文件

        public void UploadFile(string vPath, string vUID, string vPassword, string vLocalPath, string file)         {             bool status = false;             status = connectState(vPath, vUID, vPassword);             if (status)             {                 DirectoryInfo theFolder = new DirectoryInfo(vPath + "/" + file);                 string filename = vLocalPath;                 Transport(vLocalPath, vPath + "/" + file);                 //System.Diagnostics.Process.Start(vPath);             }             else             {                 mesLog.Info("未能连接!");                 //MessageBox.Show("未能连接！");             }         }

三、连接状态

        public static bool connectState(string vPath, string vUID, string vPassword)         {             bool Flag = false;             Process proc = new Process();             try             {                 proc.StartInfo.FileName = "cmd.exe";                 proc.StartInfo.UseShellExecute = false;                 proc.StartInfo.RedirectStandardInput = true;                 proc.StartInfo.RedirectStandardOutput = true;                 proc.StartInfo.RedirectStandardError = true;                 proc.StartInfo.CreateNoWindow = true;                 proc.Start();                 string dosLine = "net use " + vPath + " " + vPassword + " /user:" + vUID;                 proc.StandardInput.WriteLine(dosLine);                 proc.StandardInput.WriteLine("exit");                 while (!proc.HasExited)                 {                     proc.WaitForExit(1000);                 }                 string errormsg = proc.StandardError.ReadToEnd();                 proc.StandardError.Close();                 if (string.IsNullOrEmpty(errormsg))                 {                     Flag = true;                 }                 else                 {                     throw new Exception(errormsg);                 }             }             catch (Exception ex)             {                 //throw ex;                 //MessageBox.Show(ex.Message);             }             finally             {                 proc.Close();                 proc.Dispose();             }             return Flag;         }

四、传送

        public static void Transport(string src, string fileName)         {             FileStream inFileStream = new FileStream(src, FileMode.Open);             FileStream outFileStream = new FileStream(fileName, FileMode.OpenOrCreate);             byte[] buf = new byte[inFileStream.Length];             int byteCount;             while ((byteCount = inFileStream.Read(buf, 0, buf.Length)) > 0)             {                 outFileStream.Write(buf, 0, byteCount);             }             inFileStream.Flush();             inFileStream.Close();             outFileStream.Flush();             outFileStream.Close();             File.Delete(src);         }
