Namespace:   System.Collections.Generic
Assembly:  mscorlib (in mscorlib.dll)

property ICollection<TKey>^ Keys {
	ICollection<TKey>^ get();
}

Property Value

Type: System.Collections.Generic::ICollection<TKey>^

An ICollection<T> containing the keys of the object that implements IDictionary<TKey, TValue>.

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();
for each( String^ s in icoll )
{
    Console::WriteLine("Key = {0}", s);
}
