C# 去掉webapi返回json所带的转义字符

反序列换报错：
{"Error converting value \"{\"Result\":true,\"Code\":\"\",\"Msg\":\"success\",\"Data\":[\"/_temp/Other/png/20190425/20190425173934_7723.png\"]}\" to type ‘Abhs.Code.HttpResponseResult‘. Path ‘‘, line 1, position 118."}
数据：
"{\"Result\":true,\"Code\":\"\",\"Msg\":\"success\",\"Data\":[\"/_temp/Other/png/20190425/20190425181452_6968.png\"]}"
解决办法：用HttpResponseMessage返回json会去掉转义字符

            string json = JsonConvert.SerializeObject(result);
            return new HttpResponseMessage { Content = new StringContent(json, Encoding.GetEncoding("UTF-8"), "application/json") };
返回结果：
{"Result":true,"Code":"","Msg":"success","Data":["/_temp/Other/png/20190425/20190425181452_6968.png"]}
