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);
        }
