c# - 从 WebResponse 读取响应的最简单方法

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
    }
}

现在有了 webResponse 对象，阅读其内容的最简单方法是什么？

Answer 1

我会简单地在 WebClient 上使用异步方法 - 使用起来更容易:

        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"));

但是要回答问题；假设它是 text，类似于(注意您可能需要指定编码):

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