BitArray.IsSynchronized Property

 

Gets a value indicating whether access to the BitArray is synchronized (thread safe).

Namespace:   System.Collections
Assembly:  mscorlib (in mscorlib.dll)

Public ReadOnly Property IsSynchronized As Boolean

Property Value

Type: System.Boolean

This property is always false.

BitArray implements the IsSynchronized property because it is required by the System.Collections.ICollection interface.

Enumerating through a collection is intrinsically not a thread-safe procedure. Even when a collection is synchronized, other threads can still modify the collection, which causes the enumerator to throw an exception. To guarantee thread safety during enumeration, you can either lock the collection during the entire enumeration or catch the exceptions resulting from changes made by other threads.

The following code example shows how to lock the collection using the SyncRoot during the entire enumeration.

Dim myCollection As New BitArray(64, true)
SyncLock myCollection.SyncRoot
    For Each item In myCollection
        ' Insert your code here.
    Next item
End SyncLock

This method is an O(1) operation.
