C# - How to check if a property type is an Enum

class EnumTests
{
  public static void Run()
  {
      // convert a string into a color Enum
      Colour c = (Colour)Enum.Parse(typeof(Colour), "Red", true);
      Console.WriteLine("Colour Value: {0}", c.ToString());

      // Picking an invalid colour throws an ArgumentException. To
      // avoid this, call Enum.IsDefined() first, as follows:
      string nonColour = "OrangeGreen";

      if (Enum.IsDefined(typeof(Colour), nonColour))
          c = (Colour)Enum.Parse(typeof(Colour), nonColour, true);
      else
          Console.WriteLine("'{0}' is an undefined Color", nonColour);

      //Check if c is an Enum
      Console.WriteLine("c is an Enum = {0} ", c.GetType().IsEnum);
  }
}
