예제

다음 예제에서는 사용 하는 방법에 설명 합니다 AsyncWaitHandle 가져올 속성은 WaitHandle, 및 대리자에 대 한 비동기 호출 대기 하는 방법.The following example demonstrates how to use the AsyncWaitHandle property to get a WaitHandle, and how to wait for an asynchronous call on a delegate. 비동기 호출이 완료되면 WaitHandle 은 신호를 받으며 WaitOne 메서드를 호출하여 대기할 수 있습니다.The WaitHandle is signaled when the asynchronous call completes, and you can wait for it by calling the WaitOne method.

이 예제에서는 두 개의 클래스를 비동기적으로 호출 되는 메서드를 포함 하는 클래스의 구성 및 포함 된 클래스는 Main 메서드 호출을 수행 하 합니다.The example consists of two classes, the class that contains the method which is called asynchronously, and the class that contains the Main method that makes the call.
