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.
