Collection.IList.Insert Method

Inserts an item to the Collection object at the specified index. Implements the IList interface.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

void IList.Insert(
	int index,
	Object value
)

Parameters

index
Type: System.Int32
The zero-based index at which value should be inserted.
value
Type: System.Object
The Object to insert into the Collection object.

Implements

IList.Insert(Int32, Object)

ExceptionCondition
ArgumentOutOfRangeException

index is not a valid index in the Collection object.

NotSupportedException

The Collection object is read-only.

-or-

The Collection object has a fixed size.

NullReferenceException

value is null reference in the Collection object.

If index equals the number of items in the Collection object, 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.
