p.StartInfo.RedirectStandardOutput = true;
//p.StartInfo.FileName = Server.MapPath("a.bat");
p.StartInfo.FileName = @"E:a.bat";//如果a.bat在System32文件夹中，此处只需填写文件名即可
p.StartInfo.WorkingDirectory = @"E:";
p.StartInfo.Arguments = Server.UrlEncode(TextBox1.Text);

a.bat:
程序代码
代码如下：

@echo off
md %random%
set i=1
:loop
ping 1 -n 1 -w 1000 2nul 1nul
set /a i=%i%+1
if %i%==20 echo 返回值:%1^br^服了你,这么有耐心 & exit
goto loop

说明：当批处理和aspx不在同一目录中时，最好用WorkingDirectory设置启动的进程的初始目录为批处理所在目录，否则如上例中批处理新建的目录就应在aspx所在目录中而不是批处理所在目录了！
