以編程方式使用C＃重新啓動Windows Mobile 6.x設備

Question

我的HTC HD2無法從操作系統重新啓動，只需關閉。所以我想寫一個小程序來做到這一點。

是否有可能以編程方式重新啓動Windows Mobile 6.x設備使用C＃？

Answer 1

您應該使用記錄ExitWindowsEx API。 IOCTL只能在缺少ExitWindowsEx函數調用的平臺上使用（Pocket PC 2000,2002和2003）。有關更多信息，請參閱MSDN doc。

[DllImport("aygshell.dll", SetLastError=""true"")] 
[return: MarshalAs(UnmanagedType.Bool)] 
static extern bool ExitWindowsEx([MarshalAs(UnmanagedType.U4)]uint dwFlags, [MarshalAs(UnmanagedType.U4)]uint dwReserved); 

enum ExitWindowsAction : uint 
{ 
    EWX_LOGOFF = 0, 
    EWX_SHUTDOWN = 1, 
    EWX_REBOOT = 2, 
    EWX_FORCE = 4, 
    EWX_POWEROFF = 8 
} 

void rebootDevice() 
{ 
    ExitWindowsEx(ExitWindowsAction.EWX_REBOOT, 0); 
}

我認爲這將幫助你：Hard Reset Windows Mobile Device ..仍然這種方法不是「清晰的C＃代碼」，因爲它使用Interop，但它的工作原理，因此它可以解決你的問題。
對於軟復位：

[DllImport("coredll.dll", SetLastError=true)] 
private static extern bool KernelIoControl(int dwIoControlCode, byte[] inBuf, int inBufSize, byte[] outBuf, int outBufSize, ref int bytesReturned); 

private const uint FILE_DEVICE_HAL = 0x00000101; 
private const uint METHOD_BUFFERED = 0; 
private const uint FILE_ANY_ACCESS = 0; 

private static uint CTL_CODE(uint DeviceType, uint Function, uint Method, uint Access) 
{ 
    return ((DeviceType << 16) | (Access << 14) | (Function << 2) | Method); 
} 

public static void softReset() 
{ 
    uint bytesReturned = 0; 
    uint IOCTL_HAL_REBOOT = CTL_CODE(FILE_DEVICE_HAL, 15, METHOD_BUFFERED, FILE_ANY_ACCESS); 
    KernelIoControl(IOCTL_HAL_REBOOT, IntPtr.Zero, 0, IntPtr.Zero, 0, ref bytesReturned); 
} 

（儘管我沒有用過這個方法myself..see here）
