Parameters

index
value

The Object to insert into the IList.

Exception typeCondition

ArgumentOutOfRangeException

index is not a valid index in the IList.

NotSupportedException

The IList is read-only.

-or-

The IList has a fixed size.

NullReferenceException

value is null reference in the IList.

If index equals the number of items in the IList, then value is appended to the end.

In collections of contiguous elements, such as lists, the elements that follow the insertion point move down to accommodate the new element. If the collection is indexed, the indexes of the elements that are moved are also updated. This behavior does not apply to collections where elements are conceptually grouped into buckets, such as a hash table.

The following example demonstrates the implementation of the IList interface to create a simple list, fixed-size list. This code is part of a larger example for the IList interface.
