Insert Method

[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)

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

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.

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.
