.NET程序页面中,操作并输入cmd命令的小例子

winformsapp_operateandinputcmd:

新建form1,拖入textbox,并设为允许多行,dock设为fill,然后绑定keyup事件即可

执行代码如下：

private void txtcmdinput_keyup(object sender, keyeventargs e)

      {

          if (e.keycode == keys.enter)

          {

              int count = txtcmdinput.lines.length;

              if (count == 0) return;

              while (count > 0 && (string.isnullorempty(txtcmdinput.lines[count - 1])))

              {

                  count--;

              }

              if (count > 0)// && !string.isnullorempty(txtcmdinput.lines[count - 1]))

                  executecmd(txtcmdinput.lines[count - 1]);

          }

      }

      public void executecmd(string cmd)

      {

          system.diagnostics.process p = new system.diagnostics.process();

          p.startinfo.filename = "cmd.exe";

          p.startinfo.useshellexecute = false;

          p.startinfo.redirectstandardinput = true;

          p.startinfo.redirectstandardoutput = true;

          p.startinfo.redirectstandarderror = true;

          p.startinfo.createnowindow = true;

          p.start();                                  //设置自动刷新缓冲并更新   

          p.standardinput.autoflush = true;           //写入命令     

          p.standardinput.writeline(cmd);

          p.standardinput.writeline("exit");          //等待结束  

          txtcmdinput.appendtext(p.standardoutput.readtoend());

          p.waitforexit();

          p.close();

      }
