早安人士，我想在menuStrip上悬停时更改其菜单项的颜色.谁能帮我吗?

Good day people, I want to change the color of a menu item on my menuStrip when I hover above it. Can anyone help me?

推荐答案

您不能使用常规的MouseEnter和MouseLeave事件来执行此操作.您需要直接覆盖菜单渲染.您可以使用MenuStrip类执行以下操作:

You can't do this using the normal MouseEnter and MouseLeave events. You need to directly override the menu rendering. You can do something like this, using the MenuStrip class:

private class renderer : ToolStripProfessionalRenderer {
    public renderer() : base(new cols()) {}
}

private class cols : ProfessionalColorTable {
    public override Color MenuItemSelected {
        // when the menu is selected
        get { return Color.Blue; }
    }
    public override Color MenuItemSelectedGradientBegin {
        get { return Color.Black; }
    }
    public override Color MenuItemSelectedGradientEnd {
        get { return Color.White; }
    }
}

以防万一，您在使用MouseEnter和MouseLeave事件时会发生这种情况. (在MouseEnter事件中，它使BackgroundColor绿色，但是没有被调用):

And just in case you're interested, this is what happens when you use the MouseEnter and MouseLeave events. (Inside the MouseEnter event, it was making the BackgroundColor green, however that was not been called):
