Collection.Remove Method

Class

Microsoft.VisualBasic.Collection

Syntax

objectVariable.Remove(index)

objectvariable (required; Collection)

The instance of a

Collection from which an item is to be removed

index (required; Integer or String)

Either the 1-based ordinal position (

Integer) or the unique key (String) of an item

in the collection

Description

The Remove method removes an item from a collection based on its position or its

unique key.

Usage at a Glance

• Members of the collection that follow the removed member are automatically

moved by one ordinal position; no gaps are left in the collection. This also means

that the ordinal positions of many members may change during a deletion.

• If you are deleting multiple members of a collection by numeric index value, you

should delete them backwards—from highest index value to lowest—since the

collection is reindexed after each deletion.

• The Clear method of the

Collection class removes all items immediately.

Version Differences

Visual Basic 2005 adds support for generics to several collection-style classes. Generics

are discussed in Chapter 10.
