c# – toolStrip有menuStrip渐变背景

public class CustomToolStripRenderer : ToolStripProfessionalRenderer
{
    public CustomToolStripRenderer() { }

    protected override void OnRenderToolStripBackground(ToolStripRenderEventArgs e)
    {
        //you may want to change this based on the toolstrip's dock or layout style
        LinearGradientMode mode = LinearGradientMode.Horizontal;

        using (LinearGradientBrush b = new LinearGradientBrush(e.AffectedBounds,ColorTable.MenuStripGradientBegin,ColorTable.MenuStripGradientEnd,mode))
        {
            e.Graphics.FillRectangle(b,e.AffectedBounds);
        }
    }
}

然后设置工具条以使用此渲染器的实例.

public Form1()
{
    InitializeComponent();

    CustomToolStripRenderer r = new CustomToolStripRenderer();
    r.RoundedEdges = false;

    toolStrip1.Renderer = r;
}
