獲取一個GIF圖片，但保存成爲靜態圖片

Question

我從網站上的GIF圖片，但保存後變成靜態圖片後，我的代碼是：

string picurl = "http://www.ifanr.com/wp-content/uploads/2011/10/J1D2AYQV.gif"; 
string savepath=@"D:\test.gif"; 
string imgExt = picurl.Substring(picurl.LastIndexOf("."), picurl.Length - picurl.LastIndexOf(".")); 
WebRequest wreq = WebRequest.Create(picurl); 
wreq.Timeout = 10000; 
HttpWebResponse wresp = (HttpWebResponse)wreq.GetResponse(); 
Stream s = wresp.GetResponseStream(); 
System.Drawing.Image img = System.Drawing.Image.FromStream(s); 
if (imgExt == ".gif") 
{ 
img.Save(savepath, ImageFormat.Gif); 
} 
img.Dispose(); 
s.Dispose(); 

誰可以幫我？謝謝！

Answer 1

而是執行此操作：

using (WebClient wc = new WebClient()) 
    { 
     wc.DownloadFile("http://www.ifanr.com/wp-content/uploads/2011/10/J1D2AYQV.gif", @"D:\test.gif"); 
    } 

你的GIF圖像將保持不變。
