最简单的方法来阅读WebResponse的响应

private void RespCallback(IAsyncResult asynchronousResult) { try { WebRequest myWebRequest1 = (WebRequest)asynchronousResult.AsyncState; // End the Asynchronous response. WebResponse webResponse = myWebRequest1.EndGetResponse(asynchronousResult); } catch (Exception) { //TODO:Log the error } } 

现在拥有webResponse对象，读取其内容的最简单方法是什么？

Answer 1

我只是简单地使用WebClient上的asynchronous方法 – 更容易处理：

  WebClient client = new WebClient(); client.DownloadStringCompleted += (sender,args) => { if(!args.Cancelled && args.Error == null) { string result = args.Result; // do something fun... } }; client.DownloadStringAsync(new Uri("http://foo.com/bar")); 

但要回答这个问题， 假设它是文本 ，就像（注意你可能需要指定编码）：

  using (var reader = new StreamReader(response.GetResponseStream())) { string result = reader.ReadToEnd(); // do something fun... } 

Answer 2

如果响应来自XML，则可以使用这种方法。

  HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create("https://www.yoururl.com"); WebResponse response = myReq.GetResponse(); Stream responseStream = response.GetResponseStream(); XmlTextReader reader = new XmlTextReader(responseStream); while (reader.Read()) { if (reader.NodeType == XmlNodeType.Text) Console.WriteLine("{0}", reader.Value.Trim()); } Console.ReadLine(); 

Answer 3

 internal string Get(string uri) { using (WebResponse wr = WebRequest.Create(uri).GetResponse()) { using (StreamReader sr = new StreamReader(wr.GetResponseStream())) { return sr.ReadToEnd(); } } }
