解决：MVC对象转json包含

项目中对象转json字符串时，如下：
JsonSerializerSettings jsetting = new JsonSerializerSettings();
jsetting.DefaultValueHandling = DefaultValueHandling.Ignore;
return JsonConvert.SerializeObject(resultMoldels, Formatting.Indented, jsetting);
发现返回的字符串中包含换行符 

"{
 "result": true,
 "msg": "OK",
 "data": [
 "success",
 "123456789",
 "987654321"
 ]
}"

解决方法：
Formatting.Indented 修改成 Formatting.None
