ArrayList.Synchronized Method (IList)
Assembly: mscorlib (in mscorlib.dll)
The IList to synchronize.
Return ValueAn IList wrapper that is synchronized (thread safe).
list is a null reference (Nothing in Visual Basic).
To guarantee the thread safety of the ArrayList, all operations must be done through this wrapper.
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.
