IList.Item Property

When implemented by a class, gets or sets the element at the specified index.

[C#] In C#, this property is the indexer for the IList class.

[Visual Basic]
Default Property Item( _
   ByVal index As Integer _
) As Object
object this[
   int index
] {get; set;}
__property Object* get_Item(
 int index
__property void set_Item(
 int index,
returnValue = IListObject.Item(index);
IListObject.Item(index) = returnValue;
returnValue = IListObject(index);
IListObject(index) = returnValue;

[JScript] In JScript, you can use the default indexed properties defined by a type, but you cannot explicitly define your own. However, specifying the expando attribute on a class automatically provides a default indexed property whose type is Object and whose index type is String.

Arguments [JScript]

The zero-based index of the element to get or set.

Parameters [Visual Basic, C#, C++]

The zero-based index of the element to get or set.

Property Value

The element at the specified index.


Exception Type Condition
ArgumentOutOfRangeException index is not a valid index in the IList.
NotSupportedException The property is set and the IList is read-only.


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