The order of the keys in the returned ICollection object is unspecified, but is guaranteed to be the same order as the corresponding values in the ICollection returned by the Values property.

The following code example demonstrates how to implement the Keys property. This code example is part of a larger example provided for the IDictionary class.


public ICollection Keys
{
   get
   {
      // Return an array where each item is a key.
      Object[] keys = new Object[ItemsInUse];
      for (Int32 n = 0; n < ItemsInUse; n++)
         keys[n] = items[n].Key;
      return keys;
   }
}
