C# - Web API - Serializing Enums as strings with spaces

Question

My question is simple, but a little more specific than other questions related to serializing enumerated types as strings.

Consider the following piece of code:

using Newtonsoft.Json;
using Newtonsoft.Json.Converters;

public enum MyEnum
{
    TypeOne,
    TypeTwo,
    TypeThree
}

public class Foo
{
   [JsonConverter(typeof(StringEnumConverter))]
   public MyEnum Types { get; set; }
}

When the Web API controller sends serialized Foo objects, they may look something like this:

{
    "Type" : "TypeTwo"
}

My Question: is it possible to send serialized enums as strings with spaces before each capital letter? Such a solution would produce JSON like this:

{
    "Type" : "Type Two"
}

Let me know if there's any additional information needed to solve my problem. Thanks!

EDIT:

It's preferable if the enums are only converted to strings with spaces while serializing them to JSON. I'd like to exclude spaces while using MyEnum.ToString() on the backend.

Solution

Try adding EnumMember as shown below,

[JsonConverter(typeof(StringEnumConverter))]
public enum MyEnum
{
    [EnumMember(Value = "Type One")]
    TypeOne,
    [EnumMember(Value = "Type Two")]
    TypeTwo,
    [EnumMember(Value = "Type Three")]
    TypeThree
}

You may need to install a package called System.Runtime.Serialization.Primitives from Microsoft to use that.
