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
法一:this.pictureBox2.Image= Image.FromStream(System.Net.WebRequest.Create(http://www.pxkt.com/logo.gif).GetResponse().GetResponseStream());
法二:is.pictureBox1.ImageLocation = "http://b.hiphotos.baidu.com/news/pic/item/c995d143ad4bd113db3dc15658afa40f4afb05e5.jpg";
