How to use enum item name which contains space?

Yes, the EnumMemberAttribute is designed exactly you want.

public enum OrderStatus 
{ 
  Pending,
  Completed, 
  Cancelled, 
  Refunded, 
  [EnumMember(Value = "Partial Refund")]
  PartialRefund 
}

Need to import package

using System.Runtime.Serialization;

Thanks nik,

When I get json response through action method we get the attribute value as I wish, but when I need enum member value in C# code for server side report generation i.e. csv, excel, html etc.

I am trying following code

var pr = OrderStatus.PartialRefund.ToString()
//output "PartialRefund"

I want output as

"Partial Refund"

Use following extension method

public static class Extensions
    {
        public static string GetName<T>(this Enum enumVal) where T : System.Attribute
        {
            var type = enumVal.GetType();
            var memInfo = type.GetMember(enumVal.ToString());
            var attributes = memInfo[0].GetCustomAttributes(typeof(T), false);
            return (attributes.Length > 0) ? ((System.Runtime.Serialization.EnumMemberAttribute)attributes[0]).Value : enumVal.ToString();
        }      
    }

Use it as

var pr = OrderStatus.PartialRefund.GetName<EnumMemberAttribute>();
