【求教】C#如何实现强制结束这个进程，系统就自动重启或关机

Question

像网吧里的那种还原软件的进程，你强制退出了系统就自动重启或关机。求教C#是否可以实现这个功能可以实现的话那该如何写才对。最近对这个比较感兴趣先谢谢！

Answer 1

你自己杀掉svchost.exe进程他就强制重启了.....

Answer 2

要是想走正常渠道的话要调用user32.DLL的API
[DllImport("user32.dll")]
static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
[STAThread]
static void Main(string[] args)
{
ExitWindowsEx(ExitWindows.LogOff, ShutdownReason.MajorOther & ShutdownReason.MinorOther);
}
public enum ExitWindows : uint
{
LogOff = 0x00,      //注销
            ShutDown = 0x01,    //关机
            Reboot = 0x02,      //重启
            Force = 0x04,
PowerOff = 0x08,
ForceIfHung = 0x10
}public enum ShutdownReason : uint

Answer 3

to 3楼果然是高人 但是以我现在的实力 我不会调用系统api啊看来还是要修炼  谢谢啊

Answer 4

这个想法确实比较好 任何一个进程死了我就去调用关机命令   很好不过我还去攻克下调用系统  api  挑战下

Answer 5

调用API
 [StructLayout(LayoutKind.Sequential, Pack = 1)]
        internal struct LUID_AND_ATTRIBUTES
        {
            public LUID pLuid;
            public int Attributes;
        }
        [StructLayout(LayoutKind.Sequential, Pack = 1)]
        internal struct TOKEN_PRIVILEGES
        {
            public int PrivilegeCount;
            public LUID_AND_ATTRIBUTES Privileges;
        }
        [StructLayout(LayoutKind.Sequential, Pack = 1)]
        internal struct LUID
        {
            public int LowPart;
            public int HighPart;
        }
        public class PrivilegeException : Exception
        {
            public PrivilegeException() : base() { }
            public PrivilegeException(string message) : base(message) { }
        }        [DllImport("advapi32.dll", EntryPoint = "OpenProcessToken", CharSet = CharSet.Ansi)]
        private static extern int OpenProcessToken(IntPtr ProcessHandle, int DesiredAccess, ref IntPtr TokenHandle);

        [DllImport("user32.dll", EntryPoint = "FormatMessageA", CharSet = CharSet.Ansi)]
        private static extern int FormatMessage(int dwFlags, IntPtr lpSource, int dwMessageId, int dwLanguageId, StringBuilder lpBuffer, int nSize, int Arguments);
        private const int FORMAT_MESSAGE_FROM_SYSTEM = 0x1000;
        protected static string FormatError(int number)
        {
            StringBuilder buffer = new StringBuilder(255);
            FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM, IntPtr.Zero, number, 0, buffer, buffer.Capacity, 0);
            return buffer.ToString();
        }
        [DllImport("advapi32.dll", EntryPoint = "LookupPrivilegeValueA", CharSet = CharSet.Ansi)]

        private static extern int ExitWindowsEx(int uFlags, int dwReserved);

Answer 6

在窗口关闭事件里写代码，直接关机，可以调用shutdown

Answer 7

写个服务与你进程进行通信。通信的方式你可以任选。
当进程被KILL，就重起。
