Reboot machine from a C#/WPF app
提问by Josh Santangelo
I want to have a button in my WPF app that restarts the machine. This app is always running on Vista.
我想在我的 WPF 应用程序中有一个按钮来重新启动机器。此应用程序始终在 Vista 上运行。
The fact that a quick search hasn't turned anything up makes me think this might be harder than I wish it was... any ideas? Thanks!
快速搜索没有发现任何结果这一事实让我觉得这可能比我希望的更难......有什么想法吗？谢谢！

Try this:
尝试这个：
System.Diagnostics.Process.Start("shutdown.exe", "-r -t 0");
This starts Windows' inbuilt shutdowntool, which can also shut down or logoff a remote or the local machine.
这将启动 Windows 的内置shutdown工具，该工具还可以关闭或注销远程或本地计算机。
Here is the list of full options from ss64.com:
以下是ss64.com的完整选项列表：
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)
You'll probably notice that I have used the Linux/UNIX style of passing command-line arguments (using the '-') sign. On Windows, the convention is using '/'. This doesn't matter - the program doesn't care.
您可能会注意到我使用了传递命令行参数的 Linux/UNIX 风格（使用“-”）符号。在 Windows 上，约定使用“/”。这没关系 - 程序不在乎。

An alternative would be to use WMI (i.e. the System.Managementnamespace); Google brings up variations on this code --
另一种方法是使用 WMI（即System.Management命名空间）；谷歌提出了这个代码的变体——
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);
}

You can use the ExitWindowsExAPI. From pinvoke.net
您可以使用ExitWindowsExAPI。来自pinvoke.net

[DllImport("user32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool ExitWindowsEx(ExitWindows uFlags, ShutdownReason dwReason);
And to use it:
并使用它：
ExitWindowsEx(
ExitWindows.Reboot,
ShutdownReason.MajorOther | ShutdownReason.MinorOther | ShutdownReason.FlagPlanned
);
