Property Value

An object that can be used to synchronize access to the collection.

Remarks

Enumerating through a collection is intrinsically not a thread-safe procedure. In the rare case where enumeration contends with write accesses, you can lock the collection during the whole enumeration. To let the collection to be accessed by multiple threads for reading and writing, you must implement your own synchronization.

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

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