C#把文件上传到服务器中的指定地址-C#/.NET开发

这篇文章介绍了C#实现文件上传到服务器指定地址的方法，文中通过示例代码介绍的非常详细。对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

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);
        }
