VB.NET 中的组合键

Question

谁能帮我在 VB.NET 中读取多个按键。例如，我想读取 Control+P+H 组合键。我尝试了类似下面的代码但没有用... 在表单 Keydown 中

if e.control=true and e.keycode=keys.P and e.keycode=keys.H then
end if

好的，在阅读了您的帖子之后，据我所知，这样的事情应该可以解决问题。

Public Class Form1
Dim keyCombo As New List(Of Keys)({Keys.ControlKey, Keys.H, Keys.P})
Dim currentKeys As New List(Of Keys)

Private Sub Form1_KeyDown(sender As Object, e As KeyEventArgs) Handles Me.KeyDown
    currentKeys.Add(e.KeyCode)

    If currentKeys.Intersect(keyCombo).Count = keyCombo.Count Then
        MessageBox.Show("CTRL + H + P Has Been Pressed....")
        currentKeys.Clear()
    End If

End Sub

Private Sub Form1_KeyUp(sender As Object, e As KeyEventArgs) Handles Me.KeyUp
    currentKeys.Remove(e.KeyCode)
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    Me.KeyPreview = True
End Sub

End Class
