T

The element at the specified index.

ArgumentOutOfRangeException

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

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