解析JSON响应的最简单方法

我找到了一种无需使用任何外部API即可获取的方法

        using (var w = new WebClient())
        {
            var json_data = string.Empty;
            string url = "YOUR URL";
            // attempt to download JSON data as a string
            try
            {
                json_data = w.DownloadString(url);
                JavaScriptSerializer jsSerializer = new JavaScriptSerializer();
                var result = jsSerializer.DeserializeObject(json_data);
                Dictionary obj2 = new Dictionary();
                obj2=(Dictionary)(result);

                string val=obj2["KEYNAME"].ToString();
            }
            catch (Exception) { }
            // if string with JSON data is not empty, deserialize it to class and return its instance 
        }
