c#如何在窗体上画线、画图,我从网上搜的,运行结果没显示出有画线? 10
publicpartialclassForm1:Form{publicvoidvForm1(){InitializeComponent();Graphicsg;g=thi...
public partial class Form1 : Form
{
public void vForm1()
{
InitializeComponent();
Graphics g;
g = this.CreateGraphics();
Pen mypengreen = new Pen(Color.Green,5);
g.DrawLine(mypengreen,10,10,100,100);
}
}
然后我在Main方法里进行实例化,
Form1 a=new Form1();
a.vForm1();
