我想在我的WPF应用程序，重新启动机器的按钮。 这个应用程序总是在Vista上运行。
一个快速搜索并没有拒绝任何事了这一事实使我认为这可能是比我想这是...任何想法更难？ 谢谢！
Answer 1:
试试这个：
System.Diagnostics.Process.Start("shutdown.exe", "-r -t 0");
这将启动Windows的内置shutdown工具，它也可以关闭或注销远程或本地计算机。
下面是从全选项列表ss64.com ：
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)
你可能会注意到，我已经使用通过命令行参数（使用“ - ”）的Linux / UNIX的风格标志。 在Windows中，约定用“/”。 这并不重要 - 该程序并不关心。

您可以使用ExitWindowsEx API。 从pinvoke.net
[Flags]
public enum ExitWindows : uint
{
// ONE of the following five:
LogOff = 0x00,
ShutDown = 0x01,
Reboot = 0x02,
PowerOff = 0x08,
RestartApps = 0x40,
// plus AT MOST ONE of the following two:
Force = 0x04,
ForceIfHung = 0x10,
}
[Flags]
enum ShutdownReason : uint
{
MajorApplication = 0x00040000,
MajorHardware = 0x00010000,
MajorLegacyApi = 0x00070000,
MajorOperatingSystem = 0x00020000,
MajorOther = 0x00000000,
MajorPower = 0x00060000,
MajorSoftware = 0x00030000,
MajorSystem = 0x00050000,
MinorBlueScreen = 0x0000000F,
MinorCordUnplugged = 0x0000000b,
MinorDisk = 0x00000007,
MinorEnvironment = 0x0000000c,
MinorHardwareDriver = 0x0000000d,
MinorHotfix = 0x00000011,
MinorHung = 0x00000005,
MinorInstallation = 0x00000002,
MinorMaintenance = 0x00000001,
MinorMMC = 0x00000019,
MinorNetworkConnectivity = 0x00000014,
MinorNetworkCard = 0x00000009,
MinorOther = 0x00000000,
MinorOtherDriver = 0x0000000e,
MinorPowerSupply = 0x0000000a,
MinorProcessor = 0x00000008,
MinorReconfig = 0x00000004,
MinorSecurity = 0x00000013,
MinorSecurityFix = 0x00000012,
MinorSecurityFixUninstall = 0x00000018,
MinorServicePack = 0x00000010,
MinorServicePackUninstall = 0x00000016,
MinorTermSrv = 0x00000020,
MinorUnstable = 0x00000006,
MinorUpgrade = 0x00000003,
MinorWMI = 0x00000015,
FlagUserDefined = 0x40000000,
FlagPlanned = 0x80000000
}
[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
并使用它：
ExitWindowsEx(
ExitWindows.Reboot,
ShutdownReason.MajorOther | ShutdownReason.MinorOther | ShutdownReason.FlagPlanned
);
Answer 3:
另一种方法是使用WMI（即System.Management命名空间）; 谷歌带来了这些代码的变化 -
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);
}
