Windows 10風格的上下文菜單條

Question

有沒有辦法使用Windows 10風格的Visual Studio和Forms創建ContextMenuStrip。我知道，它的渲染器可以以有樣子的Windows Vista，7和8來改變這就是我做了什麼：

但我也想使它看起來像這樣視窗10：

有沒有辦法使用Windows Forms來做到這一點，還是應該在一些特殊的方式來完成，使用地鐵類等？

您可以實施您的自定義Renderer並覆蓋OnRenderArrow和OnRenderItemCheck並將您的自定義ColorTable傳遞給它。然後將其設置爲ContextMenu的Renderer。

代碼ColorTable：

public class MyColorTable : ProfessionalColorTable 
{ 
    public override Color MenuItemBorder 
    { 
     get { return Color.WhiteSmoke; } 
    } 
    public override Color MenuItemSelected 
    { 
     get { return Color.WhiteSmoke; } 
    } 
    public override Color ToolStripDropDownBackground 
    { 
     get { return Color.White; } 
    } 
    public override Color ImageMarginGradientBegin 
    { 
     get { return Color.White; } 
    } 
    public override Color ImageMarginGradientMiddle 
    { 
     get { return Color.White; } 
    } 
    public override Color ImageMarginGradientEnd 
    { 
     get { return Color.White; } 
    } 
} 

代碼渲染：

public class MyRenderer : ToolStripProfessionalRenderer 
{ 
    public MyRenderer() 
     : base(new MyColorTable()) 
    { 
    } 
    protected override void OnRenderArrow(ToolStripArrowRenderEventArgs e) 
    { 
     e.Graphics.SmoothingMode = SmoothingMode.AntiAlias; 
     var r = new Rectangle(e.ArrowRectangle.Location, e.ArrowRectangle.Size); 
     r.Inflate(-2, -6); 
     e.Graphics.DrawLines(Pens.Black, new Point[]{ 
     new Point(r.Left, r.Top), 
     new Point(r.Right, r.Top + r.Height /2), 
     new Point(r.Left, r.Top+ r.Height)}); 
    } 

    protected override void OnRenderItemCheck(ToolStripItemImageRenderEventArgs e) 
    { 
     e.Graphics.SmoothingMode = SmoothingMode.AntiAlias; 
     var r = new Rectangle(e.ImageRectangle.Location, e.ImageRectangle.Size); 
     r.Inflate(-4, -6); 
     e.Graphics.DrawLines(Pens.Black, new Point[]{ 
     new Point(r.Left, r.Bottom - r.Height /2), 
     new Point(r.Left + r.Width /3, r.Bottom), 
     new Point(r.Right, r.Top)}); 
    } 
} 

代碼窗體的Load：

private void Form_Load(object sender, EventArgs e) 
{ 
    this.contextMenuStrip1.Renderer = new MyRenderer(); 
}
