Implementations can vary in how they determine equality of objects; for example, the List<T> class uses Comparer<T>::Default, whereas the Dictionary<TKey, TValue> class allows the user to specify the IComparer<T> implementation to use for comparing keys.
The following code example shows how to remove a key/value pair from a dictionary using the Remove method.
This code is part of a larger example that can be compiled and executed. See System.Collections.Generic::IDictionary<TKey, TValue>.
