c#之当我提前关闭 HttpWebResponse 时，Streamreader 不工作

Uri targetUri = new Uri(targetURL);     
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(targetUri); 
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
StreamReader reader = new StreamReader(response.GetResponseStream()); 
string data = reader.ReadToEnd(); 
response.Close(); 

为什么上面的代码可以正常工作而下面的却不行？ 请注意，我在以下代码中提前关闭了响应。

Uri targetUri = new Uri(targetURL); 
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(targetUri); 
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
StreamReader reader = new StreamReader(response.GetResponseStream()); 
response.Close(); 
string data = reader.ReadToEnd(); 

请您参考如下方法:

关闭响应也会关闭响应流...因此 StreamReader 不再有任何可读取的内容。

来自 WebResponse.Close 的文档:

The Close method cleans up the resources used by a WebResponse and closes the underlying stream by calling the Stream.Close method.
