WebClient读取网页

WebClient



   
      WebClient client = new WebClient();
 Stream stream = client.OpenRead("http://www.microsoft.com/");
 StreamReader sr = new StreamReader(stream, System.Text.Encoding.UTF8);
 string str = sr.ReadLine();
 string returnvalue = string.Empty;
 while (str != null)
 {
 returnvalue += str;
 str = sr.ReadLine();
 }

 

当然WebClient远比这个强大,更多功能查看Msdn:http://msdn.microsoft.com/zh-cn/library/system.net.webclient(VS.80).aspx
