Count Property (Collection Object) 

Returns an Integer containing the number of elements in a collection. Read-only.

Public ReadOnly Property Count() As Integer

Use the Count property to determine the number of elements in a Collection object.

This example illustrates the use of the Count property to display the number of elements in a Collection Object (Visual Basic) in the variable birthdays.

    Dim birthdays As New Collection()
    birthdays.Add(New DateTime(2001, 1, 12), "Bill")
    birthdays.Add(New DateTime(2001, 1, 13), "Joe")
    birthdays.Add(New DateTime(2001, 1, 14), "Mike")
    birthdays.Add(New DateTime(2001, 1, 15), "Pete")
...    MsgBox("Number of birthdays in collection: " & CStr(birthdays.Count))

The Collection object is one-based, which means that the index values of the elements range from 1 through the value of the Count property.
