vs2005下Graphics的使用

[Swear_fling]

我想用Graphics类画图，但是，Graphics类库中不包含DrawLine()方法，怎样才能添加进去呢？请大家帮帮忙

参考CSDN

System.Drawing.Pen myPen = new System.Drawing.Pen(System.Drawing.Color.Red);
System.Drawing.Graphics formGraphics;
formGraphics = this.CreateGraphics();
formGraphics.DrawLine(myPen, 0, 0, 200, 200);
myPen.Dispose();
formGraphics.Dispose();

你上msdn上看看graphics的各个属性和方法

[wuyq11]

Pen p = new Pen(Color.Blue, 5);//设置笔的粗细为,颜色为蓝色
Graphics g = this.CreateGraphics();
//画虚线
p.DashStyle = DashStyle.Dot;//定义虚线的样式为点
g.DrawLine(p, 10, 10, 200, 10);
//自定义虚线
p.DashPattern = new float[] { 2, 1 };//设置短划线和空白部分的数组
g.DrawLine(p, 10, 20, 200, 20);

g.Dispose();
p.Dispose();

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace 绘制直线
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}

private void button1_Click(object sender, EventArgs e)
{
Graphics line = this.CreateGraphics();
line.DrawLine(Pens.Red,20,80,100,80);
line.DrawLine(Pens.Red,60,-80,60,120);
}
}
}
要在窗体里才能用graphics绘图
