Keyプロパティの例を次に示します。 このコード例は、DictionaryEntry クラスのために提供されている大規模な例の一部です。

public:
    virtual void Add(Object^ key, Object^ value)
    {
        // Add the new key/value pair even if this key already exists
        // in the dictionary.
        if (itemsInUse == items->Length)
        {
            throw gcnew InvalidOperationException
                ("The dictionary cannot hold any more items.");
        }
        items[itemsInUse++] = gcnew DictionaryEntry(key, value);
    }
public void Add(object key, object value)
{
    // Add the new key/value pair even if this key already exists in the dictionary.
    if (ItemsInUse == items.Length)
        throw new InvalidOperationException("The dictionary cannot hold any more items.");
    items[ItemsInUse++] = new DictionaryEntry(key, value);
}
Public Sub Add(ByVal key As Object, ByVal value As Object) Implements IDictionary.Add

    ' Add the new key/value pair even if this key already exists in the dictionary.
    If ItemsInUse = items.Length Then
        Throw New InvalidOperationException("The dictionary cannot hold any more items.")
    End If
    items(ItemsInUse) = New DictionaryEntry(key, value)
    ItemsInUse = ItemsInUse + 1
End Sub
