C#启动控制台程序并实时输出

主要实现启动控制台程序,把输出重定向到文本框中：

//调用函数,
        public void Exe(string filename, string args)
        {
            Process cmd = new Process();
            cmd.StartInfo.FileName = filename;
            cmd.StartInfo.Arguments = args;
            //将cmd的标准输入和输出全部重定向到.NET的程序里
            cmd.StartInfo.RedirectStandardInput = true;//标准输入
            cmd.StartInfo.RedirectStandardOutput = true;//标准输出
            cmd.StartInfo.UseShellExecute = false;//此处必须为false否则引发异常
            //
            cmd.StartInfo.CreateNoWindow = true;//不显示命令行窗口
            cmd.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
            //
            ThreadPool.QueueUserWorkItem(new WaitCallback(ExeThread), cmd);
        }
        private void ExeThread(object obj)
        {
            Process cmd = obj as Process;
            cmd.Start();
            cmd.OutputDataReceived += new DataReceivedEventHandler(cmd_OutputDataReceived);
            cmd.BeginOutputReadLine();
            //
            Application.DoEvents();
            cmd.WaitForExit();
            if (cmd.ExitCode != 0)
            {
                ShowMessage(cmd.StandardOutput.ReadToEnd());
            }
            cmd.Close();
        }
        void cmd_OutputDataReceived(object sender, DataReceivedEventArgs e)
        {
            ShowMessage(e.Data);
        }
        private delegate void ShowMessageHandler(string msg);
        private void ShowMessage(string msg)
        {
            if (this.InvokeRequired)
            {
                this.BeginInvoke(new ShowMessageHandler(ShowMessage), new object[] { msg });
            }
            else
            {
                if (msg != null)
                {
                    textBox1.AppendText(msg + "/r/n");
                }
            }
        }
