Gets an object that can be used to synchronize access to a SortedList object.
Assembly: mscorlib (in mscorlib.dll)
To create a synchronized version of the SortedList object, use the Synchronized method. However, derived classes can provide their own synchronized version of the SortedList using the property. The synchronizing code must perform operations on the of the SortedList, not directly on the SortedList. This ensures proper operation of collections that are derived from other objects. Specifically, it maintains proper synchronization with other threads that might be simultaneously modifying the SortedList object.
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 property during the entire enumeration.
Retrieving the value of this property is an O(1) operation.
