Winform常用操作
>> c#操作cmd命令
using System.Diagnostics; private string RunCmd(string command) { //实例一个Process类，启动一个独立进程 Process p = new Process(); //Process类有一个StartInfo属性，这个是ProcessStartInfo类，包括了一些属性和方法，下面我们用到了他的几个属性： p.StartInfo.FileName = "cmd.exe"; //设定程序名 p.StartInfo.Arguments = "/c " + command; //设定程式执行参数 p.StartInfo.UseShellExecute = false; //关闭Shell的使用 p.StartInfo.RedirectStandardInput = true; //重定向标准输入 p.StartInfo.RedirectStandardOutput = true; //重定向标准输出 p.StartInfo.RedirectStandardError = true; //重定向错误输出 p.StartInfo.CreateNoWindow = true; //设置不显示窗口 p.Start(); //启动 //p.StandardInput.WriteLine(command); //也可以用这种方式输入要执行的命令 //p.StandardInput.WriteLine("exit"); //不过要记得加上Exit要不然下一行程式执行的时候会当机 return p.StandardOutput.ReadToEnd(); //从输出流取得命令执行结果 } //例如实现电脑的关机 using System.Diagnostics; ProcessStartInfo ps = new ProcessStartInfo(); ps.FileName = "shutdown.exe"; ps.Arguments = "-s -t 1";//关机 // ps.Arguments = "-r -t 1";//重启 Process.Start(ps);
>> winForm启动外部.exe文件并传值
