NameObjectCollectionBase.KeysCollection.Item[Int32] Property


Gets the entry at the specified index of the collection.

 property System::String ^ default[int] { System::String ^ get(int index); };
public string this[int index] { get; }
member this.Item(int) : string
Default Public ReadOnly Property Item(index As Integer) As String



The zero-based index of the entry to locate in the collection.

Property Value

The String key of the entry at the specified index of the collection.


index is outside the valid range of indexes for the collection.


This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index] (In Visual Basic, myCollection(index)).

The C# language uses the this keyword to define the indexers instead of implementing the Item[Int32] property. Visual Basic implements Item[Int32] as a default property, which provides the same indexing functionality.

Retrieving the value of this property is an O(1) operation; setting the property is also an O(1) operation.
