如何在.NET中更改menustrips和菜单的默认背景颜色？

using System.Drawing;
using System.Windows.Forms;

namespace YourNamespace
{
    public class CustomMenuStrip : MenuStrip
    {
        public CustomMenuStrip()
        {
            // 设置MenuStrip的背景颜色
            this.BackColor = Properties.Resources.MenuStripBackgroundColor;
        }
    }
}

using System.Drawing;
using System.Windows.Forms;

namespace YourNamespace
{
    public class CustomToolStripMenuItem : ToolStripMenuItem
    {
        public CustomToolStripMenuItem()
        {
            this.OwnerDraw = true;
        }

        protected override void OnPaint(PaintEventArgs e)
        {
            // 设置菜单项的背景颜色
            e.Graphics.FillRectangle(new SolidBrush(Properties.Resources.MenuStripBackgroundColor), this.ContentRectangle);

            // 绘制其他内容，例如文本和图像
            base.OnPaint(e);
        }
    }
}
