Dim ExplorerProcess() As Process
ExplorerProcess = Process.GetProcessesByName("explorer")
ExplorerProcess(0).CloseMainWindow()

我是想在本地实现关机和重新启动，另外，小弟我对 VB 可是不太了解啊，VB 的Dim 代码往C#里怎莫插啊 😃

1.using System.Runtime.InteropServices;

using System.Runtime.InteropServices;

[DllImport("user32")]
public static extern long ExitWindowsEx(long uFlags, long dwReserved);
[DllImport("shell32")]
public static extern long ShellAbout(long uFlags, long dwReserved);

long dwReserved;
const int LOGOFF = 0;
const int SHUTDOWN = 1;
const int REBOOT = 2;

sh = ExitWindowsEx(REBOOT, dwReserved); //重启
sh = ExitWindowsEx(LOGOFF, dwReserved) //注销
h = ExitWindowsEx(SHUTDOWN, dwReserved);//关机

我有一個WMI的，
不過本地計算機實現不了

如litp兄所述，小弟我引用了ExitWindowsEx 执行后看返回值为1.xxxxxx 按理说返回值非0说明函数执行成功了，可是我的windows一点也没有关机的意思，程序也没有出现任何异常。真是奇怪！！

本地重新启动要调用winapi，上面 litp(litp) 已经说了！

才搞明白，以上几位的代码只能在95，98下用，NT XP 不行！

你也可以用（XP or higher only）：

shutdown /r /t 0 /f

你建一个类库，然后把下面的代码全部粘贴进去，覆盖掉里面的。调用这个类的Reboot就是重启，PowerOff就是关机，LogoOff就是注销！！

using System;
using System.Runtime.InteropServices;

        }

        public static void Reboot()
