C#获得重定向地址，为避免代码造成手机端排版的混乱，可适当增加文字描述,将代码往后推移

HttpWebRequest httpReq = (HttpWebRequest)WebRequest.Create("http://www.contoso.com");

httpReq.AllowAutoRedirect = false;

HttpWebResponse httpRes = (HttpWebResponse)httpReq.GetResponse();

if (httpRes.StatusCode==HttpStatusCode.Moved) 

{

   // Code for moved resources goes here.

}

// Close the response.

httpRes.Close();   

 string newUrl = httpRes.Headers["Location"];//获取重定向的网址

httpRes.Headers["Location"];//获取重定向的网址
