Question

    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，阅读其内容的最简单方法是什么？

Answer 1

我只想在WebClient上使用异步方法 - 更容易使用：

        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 text ，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，这是一种方法。

        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();
        }
    }
}
