Checking if Type instance is a nullable enum in C#

Question

How do i check if a Type is a nullable enum in C# something like

Type t = GetMyType();
bool isEnum = t.IsEnum; //Type member
bool isNullableEnum = t.IsNullab         


        

Answer 1

public static bool IsNullable(this Type type)
{
    return type.IsClass
        || (type.IsGeneric && type.GetGenericTypeDefinition == typeof(Nullable<>));
}

I left out the IsEnum check you already made, as that makes this method more general.
