// 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"); } }
