Question

我想编写一个程序，该程序将在特定的Web服务器上运行，并定期浏览到由同一Web服务器（IIS）托管的页面，以检查某些文本。如果发现某个条件为真，它将启动服务器的重启（它所驻留的服务器）。

我可以处理检查网页部分，这非常简单。但是重新启动呢？

有哪些.NET对象可以帮助解决这个问题，你能为我抛弃一些伪代码吗？我认为这应该非常简单，因为我猜测有内置的东西。

Answer 1

我使用此代码重启，注销和其他服务器......我希望这就是你想要的。

使用：

using System.Runtime.InteropServices;

代码：

    [StructLayout(LayoutKind.Sequential, Pack = 1)]
    internal struct TokPriv1Luid
    {
        public int Count;
        public long Luid;
        public int Attr;
    }

    [DllImport("kernel32.dll", ExactSpelling = true)]
    internal static extern IntPtr GetCurrentProcess();

    [DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
    internal static extern bool OpenProcessToken(IntPtr h, int acc, ref IntPtr phtok);

    [DllImport("advapi32.dll", SetLastError = true)]
    internal static extern bool LookupPrivilegeValue(string host, string name, ref long pluid);

    [DllImport("advapi32.dll", ExactSpelling = true, SetLastError = true)]
    internal static extern bool AdjustTokenPrivileges(IntPtr htok, bool disall,
    ref TokPriv1Luid newst, int len, IntPtr prev, IntPtr relen);

    [DllImport("user32.dll", ExactSpelling = true, SetLastError = true)]
    internal static extern bool ExitWindowsEx(int flg, int rea);

    public const int SE_PRIVILEGE_ENABLED = 0x00000002;
    public const int TOKEN_QUERY = 0x00000008;
    public const int TOKEN_ADJUST_PRIVILEGES = 0x00000020;
    public const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege";
    public const int EWX_LOGOFF = 0x00000000;                               //Logoff flag   
    public const int EWX_SHUTDOWN = 0x00000001;                         //Shutdown
    public const int EWX_REBOOT = 0x00000002;                               //Reboot
    public const int EWX_FORCE = 0x00000004;                                //Force Logoff, shutdown or Reboot, add like this (EWX_REBOOT | EWX_FORCE)
    public const int EWX_POWEROFF = 0x00000008;                         //Forced shutdown
    public const int EWX_FORCEIFHUNG = 0x00000010;                      //Forced Logoff, shutdown or reboot if pc hangs


    public static void DoExitWin(int flg)
    {
        bool ok;
        TokPriv1Luid tp;
        IntPtr hproc = GetCurrentProcess();
        IntPtr htok = IntPtr.Zero;
        ok = OpenProcessToken(hproc, TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, ref htok);
        tp.Count = 1;
        tp.Luid = 0;
        tp.Attr = SE_PRIVILEGE_ENABLED;
        ok = LookupPrivilegeValue(null, SE_SHUTDOWN_NAME, ref tp.Luid);
        ok = AdjustTokenPrivileges(htok, false, ref tp, 0, IntPtr.Zero, IntPtr.Zero);
        ok = ExitWindowsEx(flg, 0);
    }

像这样重新启动：

DoExitWin(EWX_REBOOT);

如果你想强行重启没有电表：

DoExitWin(EWX_REBOOT | EWX_FORCE);

如果您只想在电脑挂起或需要长时间时强行重启：

DoExitWin(EWX_REBOOT | EWX_FORCEIFHUNG);

Answer 2

只需使用System.Diagnostic.Process

执行此命令即可

shutdown -r -f

启动自重启的C＃代码？
