How do you use a SortedList<T> to store items in a specific order in C#?

• Actually, SortedList<TKey, TValue> stores key-value pairs sorted by keys.
• To store items in a specific order, use the key to represent the sorting criteria.
• Keys must be unique and implement IComparable or provide a custom

IComparer.

Example:

SortedList<int, string> sortedList = new SortedList<int, string>();

sortedList.Add(10, "Ten");

sortedList.Add(5, "Five");

sortedList.Add(20, "Twenty");

Follow:

// Items automatically sorted by keys: 5, 10, 20

If you want to sort by custom criteria, implement an IComparer and pass it to the

SortedList constructor.
