关闭PowerState S4(Shutting down to PowerState S4)

 我需要从我的WPF应用程序关闭，并确保机器进入与使用传统的Windows关闭对话框相同的电源状态。 
 
 我可以使用以下命令关闭到未知电源状态： 
 
Process.Start("shutdown", "/s /t 0");
 
 问题是使用此关闭过程，当通过按下电源按钮启动备份时，psu消耗的电流小于100毫安（通常在80和85之间），而使用对话框关闭后消耗的约为300毫安。 
 
 默认情况下，在Windows 8中使用“关闭”对话框关闭，根据系统电源状态枚举为S4。 
 
 我想关闭到相同的S4状态，而不强迫用户进行其他操作，单击“确定”关闭对话框等。 
 
 注意： 
 
 我可以通过运行以下VBScript来调用对话框，但是不想采用这种方法： 
 
 呼叫 
 
Process.Start(@"C:\PathToScript\Shutdown.vbs");
 
 VB脚本 
 
dim objShell
set objShell = CreateObject("shell.application")
objshell.ShutdownWindows
set objShell = nothing

I need to shut down from my WPF application, and ensure the machine enters the same power state as using the traditional windows shutdown dialog. 
 
I can shutdown to an unknown power state by using the following:
 
Process.Start("shutdown", "/s /t 0");
 
The problem is that using this shutdown process, when booting back up by pressing the power button, the psu draws less than 100 milliamps (usually between 80 and 85), as opposed to the ~300 milliamps drawn after using the dialog to shutdown.
 
Using the Shutdown dialog to shutdown, by default in windows 8, according the the System Power States enumeration is S4.
 
I would like to shutdown to that same S4 state, without forcing the user to make additional actions, clicking "ok" to shutdown on the dialog, etc.
 
Note:
 
I can call the dialog, by running the following VBScript, but would prefer not to take this route:
 
Call
 
Process.Start(@"C:\PathToScript\Shutdown.vbs");
 
VB Script
 
dim objShell
set objShell = CreateObject("shell.application")
objshell.ShutdownWindows
set objShell = nothing
