Collection.Remove Method (Int32)

Removes an element from a Collection object.

Namespace:  Microsoft.VisualBasic
Assembly:  Microsoft.VisualBasic (in Microsoft.VisualBasic.dll)

public void Remove(
	int Index
)

Parameters

Index
Type: System.Int32
A numeric expression that specifies the position of an element of the collection. Index must be a number from 1 through the value of the collection's Count property.

When Remove deletes an element from a collection, it decrements the collection's Count property by one. It also decrements the Index value of every element that formerly followed the deleted element in the collection.

If an element was added to the collection without a Key, you must use its Index to remove it.

This example illustrates the use of the Remove method to remove objects from a Collection object in the variable birthdays.


Dim Msg As String

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")


...


birthdays.Remove(1)
birthdays.Remove("Mike")


Following the four calls to the Add method, the Count property contains 4, element "Bill" has index value 1, and element "Pete" has index value 4.

Following the first call to Remove, Count is 3, element "Bill" is deleted, and element "Pete" has index value 3.

Following the second call to Remove, Count is 2, element "Mike" is deleted, and element "Pete" has index value 2.
