Gets a value indicating whether access to the BitArray is synchronized (thread safe).
Namespace: System.Collections
Assembly: mscorlib (in mscorlib.dll)
Syntax
'Declaration
Public ReadOnly Property IsSynchronized As Boolean
public bool IsSynchronized { get; }
Property Value
Type: System.Boolean
This property is always false.

Remarks
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.
Examples
The following code example shows how to lock the collection using the SyncRoot during the entire enumeration.
BitArray myCollection = new BitArray();
lock(myCollection.SyncRoot) {
foreach (Object item in myCollection) {
// Insert your code here.
}
}
Dim myCollection As New BitArray()
Dim item As Object
SyncLock myCollection.SyncRoot
For Each item In myCollection
' Insert your code here.
Next item
End SyncLock
This method is an O(1) operation.
