C#实现cmd命令的相同效果

自己写的，有效

 public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void button1_Click(object sender, EventArgs e)        {            try            {                string cmd = @"system info";                ExcuteCmd(cmd);                       }            catch (System.Exception ex)            {            }        }                /// <summary>        /// 执行Cmd命令        /// </summary>        public string ExcuteCmd(string c, string workDirectory=null)        {            //创建执行cmd            System.Diagnostics.Process process = new System.Diagnostics.Process();            //process.StartInfo.FileName = "cmd.exe";            process.StartInfo.FileName = @"C:\Windows\System32\cmd.exe";            //process.StartInfo.WorkingDirectory = workDirectory;            string cmdPath = @"c:\Users\vi.ta";//关键这里要跳到cmd执行命令的这里,cmd窗口使用的目录            if(textBoxPath.Text=="")            {                MessageBox.Show("请输入要执行的命令的目录");                //return null;//这里加了一个判断，根据不同用户的目录不同，输入'            }            else            {                cmdPath = textBoxPath.Text;            }            process.StartInfo.WorkingDirectory = cmdPath;//这个地方决定了运行的路径            //p.startinfo.arguments="cd " + Application.StartPath;//改变路径            //配置开发方式输入输出错误            process.StartInfo.UseShellExecute = false;//不启动shell启动程序            process.StartInfo.CreateNoWindow = true;//不创建新窗口            process.StartInfo.RedirectStandardOutput = true;//重定向错误输出            process.StartInfo.RedirectStandardInput = true;//重定向输入            //执行cmd且获取返回值            process.Start();                        //当程序输入python时，系统进入到python中，所以没有反应            process.StandardInput.WriteLine(c);//向cmd窗口发送信息 ,后面+&exit表明运行后马上退出            process.StandardInput.AutoFlush = true;//提交            process.StandardInput.WriteLine("exit");            //读取返回值            StreamReader reader = process.StandardOutput;//截取输出流            string output = reader.ReadLine();//每次读取一行            while (!reader.EndOfStream)            {                //PrintThrendInfo(output);                output += reader.ReadLine();                PrintMsg(output);            }            process.WaitForExit();//等待程序进行完退出程序            return output;  //输出返回值        }            /// <summary>        /// 打印信息至文本框        /// </summary>        /// <param name="msg">要打印的信息</param>        /// <param name="flag">true则在信息末尾打印回车，false不打印回车</param>        public  void  PrintMsg(string msg, bool flag = true)        {            try            {                this.richTextBox_ReceMsg.BeginInvoke((Action)delegate                {                    //如果RichTextBox已接受文本字符超过50000个字符则清空                    if (richTextBox_ReceMsg.Text.Length >= 100000)//richTextBox_ReceMsg.MaxLength/50000                    {                        richTextBox_ReceMsg.Clear();                    }                    if (flag)                    {                        richTextBox_ReceMsg.AppendText(msg + "\n");                    }                    else                        richTextBox_ReceMsg.AppendText(msg);                    //光标滚动到最后一行                    this.richTextBox_ReceMsg.ScrollToCaret();                });            }            catch (System.Exception ex)            {                richTextBox_ReceMsg.AppendText(ex.Message + "\n");            }        }        private void button2_Click(object sender, EventArgs e)        {            try            {                string cmd = @"ifconfig/all";                ExcuteCmd(cmd);            }            catch (System.Exception ex)            {                MessageBox.Show("测试TestThumbstick up 失败" + ex.Message);            }        }

C#两种处理cmd的方式
