RemoveFromList<T> Method

Removes all elements from a list that match the conditions specified by a given predicate. This method is thread-safe and should only be used with non-generic lists such as an System.Collections.ArrayList. For a generic list, use the RemoveAll method since it does not suffer from type-checking performance overhead.

Syntax

Visual Basic
C#

'Declaration
 
Public Shared Function RemoveFromList(Of T)( _
   ByVal list As IList, _
   ByVal match As Predicate(Of T) _
) As Integer

'Usage
 
Dim list As IList
Dim match As Predicate(Of T)
Dim value As Integer
 
value = Utilities.RemoveFromList(Of T)(list, match)

public static int RemoveFromList<T>( 
   IList list,
   Predicate<T> match
)

Parameters

list: The list of elements.
match: The Predicate delegate that determines if an element is to be removed.

Type Parameters

T: The type of elements to pass to the predicate for evaluation.

Return Value

The number of elements removed.

Remarks

This algorithm performs well on lists of all size, performing O(n).
