Why is CacheKey.Update(object) using obj.GetHasCode()? Won't that call the overriden GetHashCode method if its overriden? Is that a BadIdea?

Can we cache the MethodInfo? public class HashCodeProvider { private static MethodInfo getHashCodeMethodInfo = null; static HashCodeProvider() { Type type = typeof(object); getHashCodeMethodInfo = type.GetMethod("GetHashCode"); } public static int GetIdentityHashCode(object obj) { return (int)getHashCodeMethodInfo.Invoke(obj, null); } }
