[This documentation is for preview only, and is subject to change in later releases. Blank topics are included as placeholders.]

Inserts an item to the IList at the specified index.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

Syntax

'Declaration
Sub Insert ( _
    index As Integer, _
    value As Object _
)

void Insert(
    int index,
    Object value
)

void Insert(
    int index, 
    Object^ value
)

abstract Insert : 
        index:int * 
        value:Object -> unit 

function Insert(
    index : int, 
    value : Object
)

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 IList.

Remarks

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.
