查看后发现
SetGDIHigh注意功能是提高显示精度。因此可以将此段代码单独使用（可以放在类初始化函数内比较合理）
/// <summary>/// 设置GDI高质量模式抗锯齿/// </summary>/// <param name="g">The g.</param>public static void SetGDIHigh(this Graphics g){g.SmoothingMode = SmoothingMode.AntiAlias; //使绘图质量最高，即消除锯齿g.InterpolationMode = InterpolationMode.HighQualityBicubic;g.CompositingQuality = CompositingQuality.HighQuality;}
在类初始化函数内增加
//处理闪烁问题this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);this.SetStyle(ControlStyles.UserPaint, true);this.SetStyle(ControlStyles.ResizeRedraw, true);
一样可以解决问题。
当然也可以直接屏蔽
