PictureBox绑定图片的三种方式

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());
