This method performs a binary search; however, the elements are moved up to fill in the open spot, so this method is an O(n) operation, where n is Count.

The following code example shows how to remove a key/value pair from the sorted list using the Remove method.

This code example is part of a larger example provided for the SortedList<TKey, TValue> class.

// Use the Remove method to remove a key/value pair.
Console.WriteLine("\nRemove(\"doc\")");
openWith.Remove("doc");

if (!openWith.ContainsKey("doc"))
{
    Console.WriteLine("Key \"doc\" is not found.");
}
