Warp（）方法出错

Question

当我尝试拨打pathwraped.Warp时，我得到：

  

最好的重载方法匹配'System.Drawing.Drawing2D.GraphicsPath.Warp（System.Drawing.PointF []，System.Drawing.Drawing2d.Matrix，System.Drawing.Drawing2D.WarpMode）'有一些内部参数< / p>

protected override void OnPaint(PaintEventArgs e)
{
    Graphics graf = e.Graphics;
    GraphicsPath pathwraped = (GraphicsPath)path.Clone ();
    WrapMode wm = (WrapMode)miWarpMod.Index;

    pathwraped.Warp(apDes, path.GetBounds (), new Matrix(), wm);

    graf.DrawPath(new Pen(ForeColor), pathwraped);

}
