설명
프로세스는 하나 이상의 스레드를 만들어 해당 프로세스와 관련된 프로그램 코드 부분을 실행할 수 있습니다. 스레드가 실행하는 프로그램 코드를 지정하려면 ThreadStart 대리자 또는 ParameterizedThreadStart 대리자를 사용합니다. ParameterizedThreadStart 대리자를 사용하여 스레드 프로시저에 데이터를 전달할 수 있습니다.
스레드는 존재하는 동안 항상 ThreadState에서 정의하는 상태 중 하나 이상으로 존재합니다. 스레드에 대해 ThreadPriority에서 정의하는 예약 우선 순위를 요청할 수 있지만 운영 체제에서 해당 우선 순위를 사용할지는 보장할 수 없습니다.
GetHashCode는 관리되는 스레드에 대한 ID를 제공합니다. 스레드는 수명 동안, 값을 가져오는 응용 프로그램 도메인에 관계없이 다른 스레드의 값과 충돌하지 않습니다.
참고
관리되지 않는 호스트는 관리되는 스레드와 관리되지 않는 스레드 간의 관계를 제어할 수 있으므로 운영 체제 ThreadId는 관리되는 스레드와 고정 관계가 없습니다. 특히, 정교한 호스트에서는 CLR 호스팅 API를 사용하여 동일한 운영 체제 스레드에 대해 관리되는 여러 스레드를 예약하거나 여러 다른 운영 체제 스레드 사이로 관리되는 스레드를 이동할 수 있습니다.
