	int index
] { get; set; }

Parameters

index
Type: System.Int32

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

Type: T
The element at the specified index.

ExceptionCondition
ArgumentOutOfRangeException

index is not a valid index in the IList<T>.

NotSupportedException

The property is set and the IList<T> is read-only.

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 Item property. Visual Basic implements Item as a default property, which provides the same indexing functionality.
