VB.NET Language in a Nutshell

Class

Microsoft.VisualBasic.Collection

Syntax

objectvariable .Count

objectvariable (required; Collection Object)

Object variable referring to a Collection object

Description

Returns an Integer containing the number of members in the collection

Rules at a Glance

Collections are 1-based; that is, the index of the first element of a collection is 1. In contrast, arrays are 0-based; the index of the first element of an array is 0.

Example

For i = 1 To colMyCollection.Count Set colSubCollection = colMyCollection.Item(CStr(i)) MsgBox colSubCollection.Item("Name") Set colSubCollection = Nothing Next i

Programming Tips and Gotchas

Because collections are 1-based, you can iterate the members of a collection by using index values ranging from 1 to the value of objectvariable .Count .
