// Clear the OrderedDictionary and add new values myOrderedDictionary->Clear(); myOrderedDictionary->Add("newKey1", "newValue1"); myOrderedDictionary->Add("newKey2", "newValue2"); myOrderedDictionary->Add("newKey3", "newValue3"); // Display the contents of the "new" Dictionary using an enumerator IDictionaryEnumerator^ myEnumerator = myOrderedDictionary->GetEnumerator(); Console::WriteLine( "{0}Displaying the entries of a \"new\" OrderedDictionary.", Environment::NewLine); DisplayEnumerator(myEnumerator);
