在C中以编程方式从Win XP注销用户#

logoff windows .net c#

dbkk · 技术社区 · 17 年前

如何从C应用程序启动Windows XP用户注销?我的应用程序的操作应该产生与在xp开始菜单中单击“注销”相同的结果——如果系统要求确认,也可以。

是否有用于此的.NET或非托管API?

您可以调用exittwindowsex:

http://www.pinvoke.net/default.aspx/user32/ExitWindowsEx.html

把它们放在一起:

using System.Runtime.InteropServices;
class Class1
{
    [DllImport("user32.dll")]
    static extern bool ExitWindowsEx(uint uFlags, uint dwReason);

    [STAThread]
    static void Main(string[] args)
    {
        ExitWindowsEx(ExitWindows.LogOff, ShutdownReason.MajorOther | ShutdownReason.MinorOther); 
    }
}

[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,

    MinorSecurityFixUninstall = 0x00000018,
    MinorServicePack = 0x00000010,
    MinorServicePackUninstall = 0x00000016,
    MinorTermSrv = 0x00000020,
    MinorUnstable = 0x00000006,
    MinorUpgrade = 0x00000003,
    MinorWMI = 0x00000015,

    FlagUserDefined = 0x40000000,
    FlagPlanned = 0x80000000
}

尝试使用常量“ewx\u logoff”或0调用“exitWindowsEx”API函数。API指南告诉我第二个参数被忽略。例如,

//The import
using System.Runtime.InteropServices;

// The declaration
[DllImport("user32.dll")]
public static extern int ExitWindowsEx(int uFlags, int dwReserved);

// The call
 ExitWindowsEx(0, 0);

为了完整性起见,我发现最简单的方法是调用shutdown.exe(包含在Windows中)。

Process.Start("shutdown.exe", "-l -t 0");

这就是小脑提出的答案,只是以C的形式。

大脑是对的。这里有更多信息: Lock, Logoff, Reboot, Shutdown, Hibernate, Standby in .Net

或者你可以打电话给:

shutdown.exe -l -t 0

如果你想要一个简单的出路。我自己用的是exittwindowsex。

你不能合并 -l 具有 -t 因为某些原因,所以这些都不起作用。唯一的方法似乎是前面提到的P/Invoke。
