Kode ini adalah bagian dari contoh yang lebih besar yang dapat dikompilasi dan dijalankan. Lihat 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);
}

// 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);
}

' 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 s As String In  icoll
    Console.WriteLine("Key = {0}", s)
Next s
