ServiceStack.Text反序列化lowercase_underscore_names格式的JSON

代码：

         [Test]
         public void Test()
         {
             JsConfig.PropertyConvention = JsonPropertyConvention.Lenient;
             var json ="{\"result\":\"0\",\"result_string\":\"成功\"}";
             var resp = json.FromJson<PayResp>();
             Console.WriteLine(resp.ResultString);
         }
