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

启动EXE
string arg1 = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaa";
string arg2 = "bbbbbbbbbbbbbbbbbbbbbbbbbbbbb";

System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.WorkingDirectory = Application.StartupPath; //要启动程序路径

p.StartInfo.FileName = "EXE_NAME";//需要启动的程序名
p.StartInfo.Arguments = arg1+" "+arg2;//传递的参数
p.Start();//启动
或者
Process eg = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo(exePath,strArgs);//exePath为要启动程序路径，strArgs为要传递的参数
eg.StartInfo = startInfo;
eg.StartInfo.UseShellExecute = false;
eg.Start();

接收参数

private void Form1_Load(object sender, EventArgs e)
{
String[] CmdArgs= System.Environment.GetCommandLineArgs();
if (CmdArgs.Length > )
{
//参数0是它本身的路径
String arg0 = CmdArgs[].ToString();
String arg1 = CmdArgs[].ToString();
String arg2 = CmdArgs[].ToString();

MessageBox.Show(arg0);//显示这个程序本身路径
MessageBox.Show(arg1);//显示得到的第一个参数
MessageBox.Show(arg2);//显示得到的第二个参数
}
}
