ICollection

This interface defines the basic characteristics of collection objects and implements three properties. Count gets the number of elements contained in a collection; IsSynchronized indicates whether the collection is thread-safe, and SyncRoot returns an object that synchronizes access to the collection (this is the object itself if the implementing class does not provide a Synchronized( ) method). ICollection also implements the CopyTo( ) method for copying elements to an Array object at a specified index.

public interface ICollection : IEnumerable {
// Public Instance Properties
   public int Count{get; }
   public bool IsSynchronized{get; }
   public object SyncRoot{get; }
// Public Instance Methods
   public void CopyTo(Array array, int index);
}
