Namespace:   System.Collections.Generic
Assembly:  System (in System.dll)

public:
virtual bool Remove(
	TKey key
) sealed

Parameters

key
Type: TKey

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.");
}
