C# - JavaScriptSerializer - JSON serialization of enum as string

In C#, you can use the JavaScriptSerializer class from the System.Web.Script.Serialization namespace to serialize an enum as a string in JSON format. By default, the JavaScriptSerializer serializes enums as their integer values. However, you can customize the serialization behavior by creating a custom JavaScriptConverter that handles the serialization of enums.

Here's how you can achieve JSON serialization of an enum as a string using JavaScriptSerializer:

  1. Define a custom converter for your enum:
using System; using System.Collections.Generic; using System.Web.Script.Serialization; public class EnumStringConverter<T> : JavaScriptConverter { public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer) { throw new NotImplementedException("Deserialization is not supported."); } public override IDictionary<string, object> Serialize(object obj, JavaScriptSerializer serializer) { if (obj == null) return null; if (!typeof(T).IsEnum) throw new ArgumentException($"Type '{typeof(T).FullName}' is not an enum type."); return new Dictionary<string, object> { { "value", obj.ToString() } }; } public override IEnumerable<Type> SupportedTypes { get { return new[] { typeof(T) }; } } }
  1. Register the custom converter for your enum with the JavaScriptSerializer:
JavaScriptSerializer serializer = new JavaScriptSerializer(); serializer.RegisterConverters(new[] { new EnumStringConverter<MyEnum>() });
  1. Serialize your object using the JavaScriptSerializer:
MyEnum enumValue = MyEnum.Value1; string json = serializer.Serialize(enumValue); Console.WriteLine(json); // Output: {"value":"Value1"}

Replace MyEnum with the name of your enum type.

With this setup, the enum value will be serialized as a string in the JSON output. You can customize the serialization logic further based on your requirements.
