C#利用webrequest 通过图片src保存到本地

//url 图片地址

//记得引用using System.Net;   using System.Drawing;

 

 public void getimages(string url) {

      //创建一个request 同时可以配置requst其余属性

      System.Net.WebRequest imgRequst = System.Net.WebRequest.Create(url);

      //在这里我是以流的方式保存图片

      System.Drawing.Image downImage = System.Drawing.Image.FromStream(imgRequst.GetResponse().GetResponseStream());

      string dertory = string.Format(@"I:imgfg.cn5r{0}", DateTime.Now.ToString("yyyy-MM-dd"));

      string fileName = string.Format("{0}.jpg", DateTime.Now.ToString("HHmmssffff"));

       if (!System.IO.Directory.Exists(dertory)) {

            System.IO.Directory.CreateDirectory(dertory); }

      downImage.Save(dertory + fileName);

      downImage.Dispose();

      //用完一定要释放

   }
