This property is read-only.

Note to Inheritors

Implement this property to allow the caller of an asynchronous operation to obtain an application-defined object specified at the start of the operation.

Usage

The object returned by this property can be used to pass state information for the asynchronous operation to a AsyncCallback delegate.
