Collection<(Of <(T>)>).IList.Item Property

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

Gets or sets the element at the specified index.

Namespace: System.Collections.ObjectModel
Assembly: mscorlib (in mscorlib.dll)

Syntax

Private Property Item ( _
    index As Integer _
) As Object Implements IList.Item
Object IList.this[
    int index
] { get; set; }

Parameters

Property Value

Type: System..::.Object
The element at the specified index.

Implements

IList..::.Item[([(Int32])])

Exceptions

Exception Condition
ArgumentOutOfRangeException

index is not a valid index in the IList.

ArgumentException

The property is set and value is of a type that is not assignable to the IList.

Remarks

This property provides the ability to access a specific element in the collection by using the following syntax: myCollection[index].

The C# language uses the this keyword to define the indexers instead of implementing the IList..::.Item property. Visual Basic implements IList..::.Item 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.
