속성 값
어셈블리 확인자에서 동적으로 만든 어셈블리를 조사하는 데 사용하는 디렉터리입니다.
구현
예외
언로드된 애플리케이션 도메인에서 작업이 시도됩니다.
예제
다음 예제에서는 동적 어셈블리에 대 한 디렉터리를 사용 하 여 애플리케이션 도메인을 만듭니다, 그리고 동적 어셈블리를 내보내 및 동적 디렉터리에 저장 한 다음 새 애플리케이션 도메인에 어셈블리를 로드 및 사용 합니다.
이 예제에서는 개체를 AppDomainSetup 만들고 해당 ApplicationName 속성을 "Example"로 설정하고 해당 DynamicBase 속성을 "C:\DynamicAssemblyDir"로 설정합니다. 다음 예제의 DynamicBase 애플리케이션 이름의 해시 코드를 원래 할당 된 경로의 하위 디렉터리로 추가 되었는지는 표시할 속성입니다.
참고
이 예제의 기본 디렉터리에 예제 애플리케이션에 대 한 검색 경로 외부에 있을 것입니다. 다른 위치에서 예제를 컴파일해야 합니다. 예제를 실행할 때마다 기본 디렉터리와 모든 하위 디렉터리를 삭제합니다.
예제에서는 새 애플리케이션 도메인을 만들고 사용 하 여는 AppDomainSetup 개체입니다. 이 예제에서는 디렉터리를 만들 수 있도록 속성을 사용하여 DynamicDirectory 디렉터리의 이름을 검색합니다. (이 예제에서는 간단 하 게 만들 수 디렉터리 미리 원래 경로, 애플리케이션 이름과 애플리케이션 이름, 해시 코드를 연결 하 여.)
이 예제에는 GenerateDynamicAssembly
이라는 어셈블리를 생성 하는 메서드 DynamicHelloWorld.dll
새 애플리케이션 도메인의 동적 디렉터리에 저장 합니다. 동적 어셈블리에는 이름이 정적 메서드(Shared
Visual Basic)인 하나의 형식HelloWorld
이 포함됩니다HelloFromAD
. 이 메서드를 호출 애플리케이션 도메인의 이름을 표시 합니다.
Example
클래스에서 파생 되며 MarshalByRefObject예제에서는 새 애플리케이션 도메인 및 호출에서 클래스의 인스턴스를 만들 수 있으므로 해당 Test
메서드. 메서드는 Test
동적 어셈블리를 표시 이름으로 로드하고 정적 HelloFromAD
메서드를 호출합니다.
이 예제와 동일한 디렉터리에서 명명 DynamicHelloWorld.dll
된 어셈블리에 대한 코드를 작성하고 컴파일하여 동적 디렉터리가 일반 검색 경로 이후 검색됨을 표시할 수 있습니다. 어셈블리에는 명명HelloFromAD
된 정적 메서드가 있는 HelloWorld
클래스가 있어야 합니다. 이 메서드는 예제의 기능과 동일한 기능을 가질 필요가 없습니다. 단순히 콘솔에 문자열을 표시할 수 있습니다. 어셈블리에는 해당 버전을 1.0.0.0으로 설정하는 특성도 AssemblyVersionAttribute 있어야 합니다. 예제를 실행하면 동적 디렉터리를 검색하기 전에 현재 디렉터리에서 컴파일한 어셈블리를 찾습니다.
