Remove Method (ActivitiesCollection)

Removes the specified Activity from the collection.

Syntax

Visual Basic

'Declaration
 
Public Sub Remove( _
   ByVal activity As Activity _
) 

C#

public void Remove( 
   Activity activity
)

Parameters

activity

The Activity instance to remove from this collection.

Exceptions

Exception	Description
System.ArgumentNullException	Thrown when the activity specified to be removed from the ActivitiesCollection is null (Nothing in Visual Basic .NET). The caller must provide a non-null Activity instance that is a member of the collection for it to be removed.

Remarks

Developers would use Remove to remove an Activity (or any class extending Activity) from the ActivitiesCollection when they hold a reference to the object. If the application instead has the index, within this ActivitiesCollection, or the Activity then it should use RemoveAt.

Removing an Activity from the ActivitiesCollection does not cause the Activity to be removed from any persistence store (such as the database). The Activity will reappear on the next page request unless the caller also removes it from the persistence store (i.e., database).
