How to press the Windows button programmatically using C# SendKeys
提问by PentaPenguin
Basically I want to simulate in code a user clicking on the windows button. I know there is SendKeys which allows me to send key presses to windows if I get a handle to them, but what I can't figure out is what I need to get a handle on in order to send Windows button commands. E.g. Windows Button + L. Having read into this a bit it appears that CTRL-ESC should pop up the Start Menu also but not sure how to tell it to send the keys to Windows (if this is even possible). Any help would be much appreciated.
基本上我想在代码中模拟用户点击 Windows 按钮。我知道有 SendKeys 可以让我在我得到它们的句柄时将按键发送到 Windows，但我无法弄清楚我需要得到一个句柄才能发送 Windows 按钮命令。例如，Windows 按钮 + L。仔细阅读一下，似乎 CTRL-ESC 也应该弹出“开始”菜单，但不确定如何告诉它向 Windows 发送键（如果可能的话）。任何帮助将非常感激。
Cheers!
干杯!

I don't think you can do this using SendKeys, you will need to p/invoke to an API function instead, probably keybd_eventto send either CTRL+ESC or the Windows key.
我不认为您可以使用 SendKeys 执行此操作，您将需要 p/invoke 到 API 函数，可能是keybd_event以发送 CTRL+ESC 或 Windows 键。
Hereis an example of opening the start menu this way in VB and hereis keybd_event with its C# signature on pinvoke.net.
这是在 VB 中以这种方式打开开始菜单的示例，这里是 pinvoke.net 上带有 C# 签名的 keybd_event。

Some of the things that a user would do via a WinKey shortcut can be done programmatically in other ways. To take your WinKey+L example, you could instead just use the following statement:
用户通过 WinKey 快捷方式执行的某些操作可以通过其他方式以编程方式完成。以您的 WinKey+L 为例，您可以改为使用以下语句：
Process.Start("rundll32.exe", "user32.dll,LockWorkStation");
If you could elaborate on what exactly you're trying to accomplish, maybe there's a better way than keybd_event (as Dale has suggested).
如果你能详细说明你到底想要完成什么，也许有比 keybd_event 更好的方法（正如 Dale 所建议的那样）。
