C#利用webrequest 通過圖片src保存到本地

//url 圖片地址

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

 

 public void getimages(string url) {

      //創建一個request 同時可以配置requst其餘屬性

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

      //在這裏我是以流的方式保存圖片

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

      string dertory = string.Format(@"I:\imgfg.cn\5r\{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();

      //用完一定要釋放
