The following will return True or False depending on whether the key is pressed at that moment. From the wording of your question, I assume you are notasking about event handling, which is what the other answers have addressed.
以下将根据当时是否按下键来返回 True 或 False。从你的问题的措辞来看，我假设你不是在问事件处理，这是其他答案所解决的问题。

If Control.ModifierKeys = Keys.Shift Or Control.ModifierKeys = Keys.Control Then
' Shift, Ctrl, or Shift+Ctrl is being pressed
Else
' Neither Shift nor Ctrl is being pressed
End If

I assume you want to see on whole application. To do this, forms or controls have "keypress" or "keydown" events. You can check them with those events. Click events tab and you'll see them
我假设您想查看整个应用程序。为此，窗体或控件具有“keypress”或“keydown”事件。您可以使用这些事件检查它们。单击事件选项卡，您将看到它们
