从C＃程序关闭计算机的最佳方法是什么？
我找到了一些有用的方法 - 我会在下面发布它们 - 但它们都不是很优雅。我正在寻找一种更简单和原生的东西.net。

从Windows XP开始，在win 2000或更低版本中不可用：
这是最快捷的方式：
Process.Start("shutdown","/s /t 0");
否则像其他人一样使用P / Invoke或WMI说。
编辑：如何避免创建窗口
var psi = new ProcessStartInfo("shutdown","/s /t 0");
psi.CreateNoWindow = true;
psi.UseShellExecute = false;
Process.Start(psi);

此方法使用WMI关闭窗口。
您需要向项目添加对System.Management的引用才能使用它。
using System.Management;
void Shutdown()
{
ManagementBaseObject mboShutdown = null;
ManagementClass mcWin32 = new ManagementClass("Win32_OperatingSystem");
mcWin32.Get();
// You can't shutdown without security privileges
mcWin32.Scope.Options.EnablePrivileges = true;
ManagementBaseObject mboShutdownParams =
mcWin32.GetMethodParameters("Win32Shutdown");
// Flag 1 means we want to shut down the system. Use "2" to reboot.
mboShutdownParams["Flags"] = "1";
mboShutdownParams["Reserved"] = "0";
foreach (ManagementObject manObj in mcWin32.GetInstances())
{
mboShutdown = manObj.InvokeMethod("Win32Shutdown",
mboShutdownParams, null);
}
}

此主题提供必要的代码：http://bytes.com/forum/thread251367.html
但这是相关的代码：

老派难看的方法。使用Win32 API中的ExitWindowsEx函数。
using System.Runtime.InteropServices;
void Shutdown2()
{
const string SE_SHUTDOWN_NAME = "SeShutdownPrivilege";
const short SE_PRIVILEGE_ENABLED = 2;
const uint EWX_SHUTDOWN = 1;
const short TOKEN_ADJUST_PRIVILEGES = 32;
const short TOKEN_QUERY = 8;
IntPtr hToken;
TOKEN_PRIVILEGES tkp;
// Get shutdown privileges...
OpenProcessToken(Process.GetCurrentProcess().Handle,
TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, out hToken);
tkp.PrivilegeCount = 1;
tkp.Privileges.Attributes = SE_PRIVILEGE_ENABLED;
LookupPrivilegeValue("", SE_SHUTDOWN_NAME, out tkp.Privileges.pLuid);
AdjustTokenPrivileges(hToken, false, ref tkp, 0U, IntPtr.Zero,
IntPtr.Zero);
// Now we have the privileges, shutdown Windows
ExitWindowsEx(EWX_SHUTDOWN, 0);
}
// Structures needed for the API calls
private struct LUID
{
public int LowPart;
public int HighPart;
}
private struct LUID_AND_ATTRIBUTES
{
public LUID pLuid;
public int Attributes;
}
private struct TOKEN_PRIVILEGES

public LUID_AND_ATTRIBUTES Privileges;
}
[DllImport("advapi32.dll")]

int DesiredAccess, out IntPtr TokenHandle);
[DllImport("advapi32.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
static extern bool AdjustTokenPrivileges(IntPtr TokenHandle,
[MarshalAs(UnmanagedType.Bool)]bool DisableAllPrivileges,

在生产代码中，您应该检查API调用的返回值，但我将其留下以使示例更清晰。

短而甜蜜。打电话给外部程序：
using System.Diagnostics;
void Shutdown()
{
Process.Start("shutdown.exe", "-s -t 00");
}
注意：这会调用Windows的Shutdown.exe程序，因此它只有在该程序可用时才有效。 您可能在Windows 2000上遇到问题（其中shutdown.exe仅在资源工具包中可用）或XP Embedded。

我在尝试使用上面接受的WMI方法时遇到了麻烦，因为尽管以管理员身份运行该程序，但我始终没有保留异常。
解决方案是让进程为自己请求权限。我在一个叫Richard Hill的家伙写的http://www.dotnet247.com/247reference/msgs/58/292150.aspx找到了答案。

我尝试roomaroo's WMI method关闭Windows 2003 Server，但是在我将'[STAThread]'（即“Single Threaded Apartment”线程模型）添加到Main（）声明之前它不会工作：
[STAThread]
public static void Main(string[] args) {
Shutdown();
}
然后我试图从一个线程关闭，为了让它工作，我不得不将线程的“公寓状态”设置为STA：
using System.Management;
using System.Threading;
public static class Program {
[STAThread]
public static void Main(string[] args) {
Thread t = new Thread(new ThreadStart(Program.Shutdown));
t.SetApartmentState(ApartmentState.STA);
t.Start();
...
}
public static void Shutdown() {
// roomaroo's code
}
}
我是C＃noob，所以我不完全确定STA线程在关闭系统方面的重要性（即使在阅读了上面发布的链接之后）。也许别人可以详细说明......？

使用shutdown.exe。为了避免传递args，复杂执行的问题，从WindowForms执行使用PowerShell执行脚本：
using System.Management.Automation;
...
using (PowerShell PowerShellInstance = PowerShell.Create())
{
PowerShellInstance.AddScript("shutdown -a; shutdown -r -t 100;");
// invoke execution on the pipeline (collecting output)
Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
}
System.Management.Automation.dll应安装在操作系统上，并在GAC中提供。
