C#的实现FTP传送文件

C#实现FTP传送文件

简介：

接上文实现对FTP的传送文件，此文和上文可以说是如出一辙，不过此文是通过cmd进行建立连接的，建立连接后也是通过以下几个步骤实现操作。建立文件的层级结构如上文，这里就不啰嗦了。C#实现FTP上传资料

1.主方法进行调用：

this.ftpOperation.UploadFile(vIMSPath, vUID, vPassword, vLocalPath + "/" + txtFile, txtFile);

2.ftpOperation.cs 文件中的实现操作方法

2.1 主方法中调用的方法：

  public void UploadFile(string vPath, string vUID, string vPassword, string vLocalPath, string file)
        {
            bool status = false;
            //
            status = connectState(vPath, vUID, vPassword);//通过cmd进行建立连接
            if (status)
            {
                DirectoryInfo theFolder = new DirectoryInfo(vPath + "/" + file);
                string filename = vLocalPath;
                Transport(vLocalPath, vPath + "/" + file);//传送文件
                System.Diagnostics.Process.Start(vPath);
            }
            else
            {
                MessageBox.Show("未能连接！");
            }
        }

2.2 通过调用cmd进行建立连接：

 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;
        }

2.3 传送文件：

public static void Transport(string src, string fileName)
        {
            FileStream inFileStream = new FileStream(src, FileMode.Open);
            //if (!Directory.Exists(dst))
            //{
            //    Directory.Move(src,dst);
            //}
            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);//删除本地文件
        }
