Im folgenden Codebeispiel wird die Änderung einer OrderedDictionary Auflistung veranschaulicht. In diesem Beispiel wird die Count Eigenschaft verwendet, um das letzte Element in der OrderedDictionary. Dieser Code ist Teil eines größeren Codebeispiels, das angezeigt OrderedDictionarywerden kann.

// Modifying the OrderedDictionary
if (!myOrderedDictionary->IsReadOnly)
{
    // Insert a new key to the beginning of the OrderedDictionary
    myOrderedDictionary->Insert(0, "insertedKey1", "insertedValue1");

    // Modify the value of the entry with the key "testKey2"
    myOrderedDictionary["testKey2"] = "modifiedValue";

    // Remove the last entry from the OrderedDictionary: "testKey3"
    myOrderedDictionary->RemoveAt(myOrderedDictionary->Count - 1);

    // Remove the "keyToDelete" entry, if it exists
    if (myOrderedDictionary->Contains("keyToDelete"))
    {
        myOrderedDictionary->Remove("keyToDelete");
    }
}
