Type.IsEnum Property in Portable Class Library

Question

I'm trying to code in a Portable Class Library using ASP.NET Core 1.0, the following instruction:

public static void WriteMessage<T>(T value)
{
    if (typeof(T).IsEnum)
    {
        Debug.Print("Is enum")
    }
    else
    {
        Debug.Print("Not Is enum")
    }
}

But this code does not compile because the compiler says that the property IsEnum is non present on Type.

Any suggestions?

documentation says : "If the current Type represents a type parameter in the definition of a generic type or generic method, this property always returns false." this may be relevant, too – Foehn

Some functionality from Type was moved to TypeInfo in .NET Core.

typeof(T).GetTypeInfo().IsEnum

Hi Gabriel, I try to use your code but the function GetTypeInfo() is not present on Type. what is wrong? – Arlon

GetTypeInfo() is an extension method from IntrospectionExtensions. Add using System.Reflection to your class. – Jacindajacinta

It's right!!! I forgot the "Using". Thank you Gabriel!! now it works :-) – Arlon

This also worked for me. @Arlon mind marking as answer so it can float to the top. – Excavator
