SortedDictionary.System.Collections.ICollection.IsSynchronized Property

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

Namespace: System.Collections.Generic
Assembly: System (in system.dll)

bool ICollection.IsSynchronized { get; }
Not applicable.

Property Value

true if access to the ICollection is synchronized (thread safe); otherwise, false. In the default implementation of SortedDictionary, this property always returns false.

Default implementations of collections in the System.Collections.Generic namespace are not synchronized.

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 can cause 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 System.Collections.ICollection.SyncRoot property returns an object that can be used to synchronize access to the ICollection. Synchronization is effective only if all threads lock the object before accessing the collection.

Getting the value of this property is an O(1) operation.
