次の例は、各マウスボタンのボタンの状態を確認することによって現在どのボタンが押されているかを判断するマウスイベントハンドラーを示しています。The following example shows a mouse event handler that determines which buttons are currently pressed by checking the button state of each mouse button.

private void MouseDownHandler(object sender, MouseEventArgs e)
{
    if (e.RightButton == MouseButtonState.Pressed)
    {
        MessageBox.Show("The Right Mouse Button is pressed");
    }

    if (e.LeftButton == MouseButtonState.Pressed)
    {
        MessageBox.Show("The Left Mouse Button is pressed");
    }

    if (e.MiddleButton == MouseButtonState.Pressed)
    {

        MessageBox.Show("The Middle Mouse Button is pressed");
    }

    if (e.XButton1 == MouseButtonState.Pressed)
    {
        MessageBox.Show("The XButton1 Mouse Button is pressed");
    }

    if (e.XButton2 == MouseButtonState.Pressed)
    {
        MessageBox.Show("The XButton2 Mouse Button is pressed");
    }
}
Private Sub MouseDownHandler(ByVal sender As Object, ByVal e As MouseEventArgs)
    If e.RightButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Right Mouse Button is pressed")
    End If

    If e.LeftButton = MouseButtonState.Pressed Then
        MessageBox.Show("The Left Mouse Button is pressed")
    End If

    If e.MiddleButton = MouseButtonState.Pressed Then

        MessageBox.Show("The Middle Mouse Button is pressed")
    End If

    If e.XButton1 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton1 Mouse Button is pressed")
    End If

    If e.XButton2 = MouseButtonState.Pressed Then
        MessageBox.Show("The XButton2 Mouse Button is pressed")
    End If
End Sub
