Represents a handle that has been registered when calling RegisterWaitForSingleObject. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.(Inherited from MarshalByRefObject.)
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Retrieves the current lifetime service object that controls the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
Obtains a lifetime service object to control the lifetime policy for this instance.(Inherited from MarshalByRefObject.)
Returns a string that represents the current object.(Inherited from Object.)
Cancels a registered wait operation issued by the RegisterWaitForSingleObject method.
The following example shows how to use ato determine why a callback method is called, and how to unregister a task if the callback occurred because the wait handle was signaled.
The example also shows how to use the RegisterWaitForSingleObject method to execute a specified callback method when a specified wait handle is signaled. In this example, the callback method is WaitProc, and the wait handle is an AutoResetEvent.
The example defines a TaskInfo class to hold the information that is passed to the callback when it executes. The example creates a TaskInfo object and assigns it some string data. The that is returned by the RegisterWaitForSingleObject method is assigned to the Handle field of the TaskInfo object so that the callback method has access to the .
In addition to specifying TaskInfo as the object to pass to the callback method, the call to the RegisterWaitForSingleObject method specifies the AutoResetEvent that the task will wait for, a WaitOrTimerCallback delegate that represents the WaitProc callback method, a one second time-out interval, and multiple callbacks.
When the main thread signals the AutoResetEvent by calling its Set method, the WaitOrTimerCallback delegate is invoked. The WaitProc method tests to determine whether a time-out occurred. If the callback was invoked because the wait handle was signaled, the WaitProc method unregisters the , stopping additional callbacks. In the case of a time-out, the task continues to wait. The WaitProc method ends by printing a message to the console.
