public override sealed T this[
	int index
] { get; set; }

public:
virtual property T default[int index] {
	T get (int index) override sealed;
	void set (int index, T value) override sealed;
}

Parameters

index

Type: SystemInt32
The index of the item to get or set. The first item in the list has index 0, the last item has index Count-1.

Return Value

Implements

Gettingor setting an item takes time O(log N), where N is the number of items in the list.

To process each of the items in the list, using GetEnumerator() or a foreach loop is more efficient that accessing each of the elements by index.
