Examples

This example illustrates the use of the Count property to display the number of elements in a Collection object 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.

Remarks

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