SortedDictionary<(Of <(TKey, TValue>)>).ValueCollection.ICollection.IsSynchronized Property
[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]
Gets a value indicating whether access to the ICollection is synchronized (thread safe).
Namespace: System.Collections.Generic
Assembly: System (in System.dll)
Syntax
Private ReadOnly Property IsSynchronized As Boolean
Implements ICollection.IsSynchronized
bool ICollection.IsSynchronized { get; }
Property Value
Type: System..::.Boolean
true if access to the ICollection is synchronized (thread safe); otherwise, false. In the default implementation of SortedDictionary<(Of <(TKey, TValue>)>)..::.ValueCollection, this property always returns false.
Implements
ICollection..::.IsSynchronized
Remarks
Default implementations of collections in the System.Collections.Generic namespace are not synchronized.
Enumerating through a collection is intrinsically not a thread-safe procedure. To guarantee thread safety during enumeration, you can lock the collection during the entire enumeration. To allow the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.
The 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.
