JSON StringEnumConverter Not Working

Question

I have a class contains an enum property and using newtonsoft.json serilaizer I am serializing an instance of it . I want the output of serializing this property to be the string value of the property,so I used StringEnumConverter but the output was like this

** without converter : "FailOrPassProperty":1

** with converter : "FailOrPassProperty":"1"

So using the converter it seems like it is getting the ToString() of the integer

I have tried this solution but it didn't work: JSON serialization of enum as string

Note: I cannot use attribute decoration due to business rules.

check this out :

[TestClass] public class JsonStringTest { [TestMethod] public void EnumToStringSerializationTest() { var testMe = new TestMe() { UserType = UserType.User, }; var settings = new JsonSerializerSettings(); settings.Converters.Add(new StringEnumConverter()); var jsonString = JsonConvert.SerializeObject(testMe, settings); Assert.AreEqual(jsonString, "{\"UserType\":\"User\"}"); } } public class TestMe { public UserType UserType { get; set; } } public enum UserType { Admin = 1, User = 2 }

Update :

Just wanted to add this note : make sure that your enum items doesn't have EnumMember Attribute because the StringEnumConverter will use this value instead of the enum item name.
