我想在重新啓動機器的WPF應用程序中有一個按鈕。此應用程序始終在Vista上運行。從C#/ WPF應用程序重新啓動機器
事實上,一個快速搜索沒有變成什麼讓我覺得這可能比我希望它更難......任何想法?謝謝!

試試這個:
System.Diagnostics.Process.Start("shutdown.exe", "-r -t 0");
這將啓動Windows的內置shutdown
工具,它也可以關閉或註銷遠程或本地計算機。
這裏是所有的選項,從ss64.com名單:
Syntax SHUTDOWN [logoff_option] [/m \\Computer] [options] logoff_option: /i Display the GUI (must be the first option) /l Log off. This cannot be used with /m or /d option /s Shutdown /r Shutdown and Restart /a Abort a system shutdown. (only during the time-out period) /p Turn off the local computer with no time-out or warning (only with /d) /h Hibernate the local computer (only with /f) /e Document the reason for an unexpected shutdown of a computer Options: /m \\Computer : A remote computer to shutdown. /t:xxx : Time until system shutdown in seconds. The valid range is xxx=0-600 seconds. [default=30] /c "Msg" : An optional shutdown message [Max 127 chars] /f : Force running applications to close. This will not prompt for File-Save in any open applications. so will result in a loss of all unsaved data!!! /d u:xx:yy : List a USER reason code for the shutdown. /d P:xx:yy : List a PLANNED reason code for the shutdown. xx Specifies the major reason code (0-255) yy Specifies the minor reason code (0-65536)
你可能會注意到,我已經使用通過命令行參數(使用「 - 」)的Linux/UNIX的風格標誌。在Windows上,約定使用'/'。這並不重要 - 程序不關心。
另一種方法是使用WMI(即System.Management
命名空間);谷歌提出了此代碼的變化 -
ManagementClass W32_OS = new ManagementClass("Win32_OperatingSystem")
ManagementBaseObject inParams, outParams;
int result;
W32_OS.Scope.Options.EnablePrivileges = true;
foreach(ManagementObject obj in W32_OS.GetInstances())
{
inParams = obj.GetMethodParameters("Win32Shutdown");
inParams["Flags"] = 6; //ForcedReboot; -- fixed to restart rather than shutdown
inParams["Reserved"] = 0;
outParams = obj.InvokeMethod("Win32Shutdown", inParams, null)
result = Convert.ToInt32(outParams["returnValue"]);
if (result !=0) throw new Win32Exception(result);
}
您可以使用ExitWindowsEx
API。從pinvoke.net
[Flags]
public enum ExitWindows : uint

// ONE of the following five:
LogOff = 0x00,
ShutDown = 0x01,
Reboot = 0x02,

// plus AT MOST ONE of the following two:

}

}
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
,並使用它:
ExitWindowsEx(
ExitWindows.Reboot,
ShutdownReason.MajorOther | ShutdownReason.MinorOther | ShutdownReason.FlagPlanned
);
這是行不通的,除非您還調整進程令牌來獲得關機的權限。請參閱http://ithoughthecamewithyou.com/post/Reboot-computer-in-C-NET.aspx,以獲得正確執行此操作的類。 – 2010-09-11 18:30:55
