推荐答案

您应该创建一个自定义ToolStripRenderer，看看它-

You should create a custom ToolStripRenderer, take a look at this - How to: Set the ToolStrip Renderer for an Application

1. 您必须创建一个这样的自定义渲染器:

1. You have to create a custom renderer like this:

class CutomToolStripMenuRenderer : ToolStripProfessionalRenderer
{
    protected override void OnRenderMenuItemBackground(ToolStripItemRenderEventArgs e)
    {
        if (e.Item.Enabled)
        base.OnRenderMenuItemBackground(e);
    }

    protected override void OnRenderButtonBackground(ToolStripItemRenderEventArgs e)
    {
        if (e.Item.Enabled)
        base.OnRenderMenuItemBackground(e);
    }
} 

然后将此渲染器设置为菜单栏:

And then set this renderer to your menu strip:

menuStrip1.Renderer = new CustomToolStripRenderer();
