Question 88204 in ASP.NET Question posted in
The official documentation can be found here.

serialization of enum results in int – Asp.net

When i do a GET request to retrieve my list of Persons the enums(Title) get converted into integers:


class Person {

public Title PersonTitle{ get; set;}
public string Name { get; set;}


}

enum Title {
   STUDENT,
   TEACHER,
   DIRECTOR
}

Let’s Say we have the following situation:

Person first = new Person(){
  PersonTitle = Title.STUDENT,
  Name = "Dave"
}

this wil result in the following JSON:

[
 {
   "Name" : "Dave",
   "PersonTitle" : 1,
 }
]

How do I get the real value of the enum (STUDENT in this case) ?

    The only code that had to be changed was:

    Before :

    public enum Title {
   STUDENT,
   TEACHER,
   DIRECTOR
}

    After :

    using using System.Text.Json.Serialization;
[JsonConverter(typeof(JsonStringEnumConverter))]
public enum Title {
   STUDENT,
   TEACHER,
   DIRECTOR
}

    Now the response looks like:

    
[
 {
   "Name" : "Dave",
   "PersonTitle" : "Student",
 }
]

    you can set the JsonConverterAttribute

    class Person {

[JsonConverter(typeof(StringEnumConverter))]
public Title PersonTitle{ get; set;}
public string Name { get; set;}


}

    Updating Enum with EnumMemberAttribute

    enum Title {
   [EnumMember(Value = "Student")]
   STUDENT,
   [EnumMember(Value = "Teacher")]
   TEACHER,
   [EnumMember(Value = "Director")]
   DIRECTOR
}

    You need to add the adequate converter to the JSON serializer.

    System.Text.Json:

    Json.NET:
