Parameters

index: Int32

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

The element at the specified index.

Implements

Item[Int32]

Exceptions

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

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.
