Question

怎样在C#控件LABEL里绘图，比如画一条直线，在LABEL载入时，让其显示

请给出源码

Answer 1

重写这个控件

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;
using System.Drawing;

class newlabel : Label
{
protected override void OnPaint(PaintEventArgs e)
{
float lineHeght,lineWidth;
lineHeght = this.Height/2;
lineWidth = this.Width;
base.OnPaint(e);
e.Graphics.DrawLine(Pens.Red, 0, lineHeght, lineWidth, lineHeght);
}

}

你只需要在form初始化时，Label lable1 = new newlabel();

就可以了
