IDictionary<TKey, TValue>.Keys Property

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

The following code example shows how to enumerate keys alone using the Keys property.

This code is part of a larger example that can be compiled and executed. See System.Collections.Generic.IDictionary<TKey, TValue>.

// To get the keys alone, use the Keys property.
icoll = openWith.Keys;

// The elements of the ValueCollection are strongly typed 
// with the type that was specified for dictionary values.
Console.WriteLine();
foreach( string s in icoll )
{
    Console.WriteLine("Key = {0}", s);
}
