Thanks for your help Jeff, I tried your solution and it worked.
I had come up with the following, but I think yours is better(and
implemented it).
Object[] objs = property.GetCustomAttributes(false);
List<string> search = new List<string>();
foreach (object attribute in objs)
{
search.Add( ((Attribute)attribute).TypeId.ToString() );
}
Assert.IsTrue(search.Contains("MyAttribute"));
Assert.IsTrue(search.Contains("MyOtherAttribute"));
