【WinForm】编程重绘控件方法

以panel为例：

private void panel1_Paint(object sender, PaintEventArgs e)
{
    ControlPaint.DrawBorder(e.Graphics,
                                this.panel1.ClientRectangle,
                                Color.LightSeaGreen,1,
                                ButtonBorderStyle.Solid,
                                Color.LightSeaGreen,1,
                                ButtonBorderStyle.Solid,
                                Color.LightSeaGreen,1,
                                ButtonBorderStyle.Solid,
                                Color.LightSeaGreen,1,
                                ButtonBorderStyle.Solid);
}

首先在Form.cs中添加方法

this.panel1.Paint += new System.Windows.Forms.PaintEventHandler(this.panel1_Paint);

在Designer中注册重绘方法，OK完成，即可对控件进行重绘
