推荐答案

要更改菜单项的外观，应使用 ToolStripProfessionalRenderer 和自定义的 ProfessionalColorTable 。

To change appearance of menu item you should use a ToolStripProfessionalRenderer using a custom ProfessionalColorTable.

要更改该颜色，您应该覆盖自定义颜色表的 ImageMarginGradientBegin 属性并返回所需的颜色。

To change that color, you should override ImageMarginGradientBegin property of custom color table and return the color you want.

例如，您可以拥有：

public class CustomColorTable : ProfessionalColorTable
{
    public override Color ImageMarginGradientBegin
    {
        get { return Color.Red; }
    }
    public override Color ImageMarginGradientMiddle
    {
        get { return Color.Green; }
    }
    public override Color ImageMarginGradientEnd
    {
        get { return Color.Blue; }
    }
    public override Color ToolStripDropDownBackground
    {
        get { return Color.Yellow; }
    }

    public override Color MenuItemSelected
    {
        get { return Color.Pink; }
    }

    //You should also override other properties if you need.
    //This is just a sample code to show you the solution
}

然后在表单中加载：

private void Form_Load(object sender, EventArgs e)
{
    ToolStripManager.Renderer = new ToolStripProfessionalRenderer(new CustomColorTable());
}
