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 bool IsSynchronized { get; }

Property Value

Type: System.Boolean
This property is always false.

Implements

ICollection.IsSynchronized

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.

BitArray myCollection = new BitArray();
  lock(myCollection.SyncRoot) {
  foreach (Object item in myCollection) {
  // Insert your code here.
  }
 }

This method is an O(1) operation.
