Assembly:  WindowsBase (in WindowsBase.dll)

member WriteLock : IDisposable with get

Property Value

Type: System.IDisposable
An object that can be used to establish a lock on the data table members and then be appropriately disposed with a using construct.

In derived classes, all modifications to the underlying data table should occur within a using (WriteLock) { ... } clause. These modifications may be necessary if your class supports a more sophisticated AddListener implementation that requires more data beyond the source and the listener, and uses the Item collection to store the extra information.
