Winform绑定图片的三种模式

1.绝对路径: 
this.pictureBox2.Image=Image.FromFile("D:\\001.jpg"); 

2.相对路径: 
Application.StartupPath;  
可以得到程序根目录  
this.pictureBox2.Image=Image.FromFile(Application.StartupPath "\\1.gif"); 

3.获得网络图片的路径 

this.pictureBox2.Image= Image.FromStream(System.Net.WebRequest.Create(http://www.pxkt.com/logo.gif).GetResponse().GetResponseStream());
