Collections discrepencies

Published on In Programming Tags #architecture

When the collection had their "Generic" version added, some features were changed:

  • IsSynchronized and SyncRoot do not exist in the ICollection<T>, when they exist in the ICollection.
  • IList<T> does not declare a IsFixedSize property.
  • The List<T> have an instance AsReadOnly method than returns a new ReadOnly version of the list, while ArrayList have a ReadOnly static method to do the same.
  • ReadOnly, Synchronized and FixedSize version where hidden and available to instantiation only through static method, whereas they are public derived class now.

The framework is getting messier... I am hoping, without really believing, that Microsoft will attempt to clean this up and make good use of the Obsolete attribute.
