C#操作windows系统进程的方法

System.Diagnostics.Process p=Process.Start("notepad.exe","File.txt");
Thread.Sleep(2000);
p.Kill();

ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");
psi.Arguments = @"/c copy c:\1.txt lpt1";
psi.CreateNoWindow = true;
psi.UseShellExecute = false;//默认为true, 使用外壳程序启动进程。否则，直接从可执行文件创建进程。
Process p = Process.Start(psi);
if (!p.WaitForExit(1000 * 7))//启动外部程序，等待其退出
{
    p.Kill();
}
p.Close();

ProcessStartInfo psi = new ProcessStartInfo("cmd.exe");//FileName
psi.RedirectStandardInput = true;
psi.RedirectStandardOutput = true;
psi.CreateNoWindow = true;//将此属性设置为false，就能重定向进程。。。
psi.UseShellExecute = false;//
Process p = Process.Start(psi);
StreamWriter sw = p.StandardInput;
StreamReader sr = p.StandardOutput;
sw.WriteLine(@"/c copy c:\1.txt lpt1");
sw.Close();
Console.Write(sr.ReadToEnd());
sr.Close();
p.Close();
