WeakEventManager.ReadLock Property

Establishes a read-lock on the underlying data table, and returns an IDisposable.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

member ReadLock : 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, queries to the table contained in Item should always occur within a using (ReadLock) { ... } clause, except for queries that are already within a write lock. These queries 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.
