我在以下代码上遇到错误。

HttpWebRequest webRequest = WebRequest.Create(URL) as HttpWebRequest;
webRequest.CookieContainer = cookies;
StreamReader responseReader = new StreamReader(webRequest.GetResponse().GetResponseStream());
HttpWebResponse response = (HttpWebResponse)webRequest.GetResponse();
response.Cookies = webRequest.CookieContainer.GetCookies(webRequest.RequestUri); //Error here
string responseData = responseReader.ReadToEnd();
responseReader.Close();

错误：System.InvalidOperationException：提交请求后无法执行此操作。在System.Net.HttpWebRequest.GetResponse（）

上面的代码有什么问题？
