설명

CodeTryCatchFinallyStatement 는 코드 블록을 나타내는 try/catch 데 사용할 수 있습니다.

속성에는 TryStatements 블록 내에서 실행할 문이 포함되어 있습니다 try . 속성에는 CatchClauses catch된 catch 예외를 처리하는 절이 포함되어 있습니다. 속성에는 FinallyStatements 블록 내에서 실행할 문이 포함되어 있습니다 finally .

참고

모든 언어가 블록을 지원하는 try/catch 것은 아닙니다. 플래그를 Supports 사용하여 메서드를 GeneratorSupport.TryCatchStatements 호출하여 코드 생성기가 블록을 지원하는지 여부를 확인합니다/trycatch.

생성자

CodeTryCatchFinallyStatement()	CodeTryCatchFinallyStatement 클래스의 새 인스턴스를 초기화합니다.
CodeTryCatchFinallyStatement(CodeStatement[], CodeCatchClause[])	try 및 catch 절에 대해 지정한 문을 사용하여 CodeTryCatchFinallyStatement 클래스의 새 인스턴스를 초기화합니다.
CodeTryCatchFinallyStatement(CodeStatement[], CodeCatchClause[], CodeStatement[])	try 절, catch 절 및 finally 문에 대해 지정한 문을 사용하여 CodeTryCatchFinallyStatement 클래스의 새 인스턴스를 초기화합니다.

속성

CatchClauses	사용할 catch 절을 가져옵니다.
EndDirectives	끝 지시문이 포함된 CodeDirectiveCollection 개체를 가져옵니다. (다음에서 상속됨 CodeStatement)
FinallyStatements	사용할 finally 문을 가져옵니다.
LinePragma	코드 문이 있는 줄을 가져오거나 설정합니다. (다음에서 상속됨 CodeStatement)
StartDirectives	시작 지시문이 포함된 CodeDirectiveCollection 개체를 가져옵니다. (다음에서 상속됨 CodeStatement)
TryStatements	try할 문을 가져옵니다.
UserData	현재 개체에 대해 사용자 정의 가능한 데이터를 가져옵니다. (다음에서 상속됨 CodeObject)

메서드

Equals(Object)	지정된 개체가 현재 개체와 같은지 확인합니다. (다음에서 상속됨 Object)
GetHashCode()	기본 해시 함수로 작동합니다. (다음에서 상속됨 Object)
GetType()	현재 인스턴스의 Type을 가져옵니다. (다음에서 상속됨 Object)
MemberwiseClone()	현재 Object의 단순 복사본을 만듭니다. (다음에서 상속됨 Object)
ToString()	현재 개체를 나타내는 문자열을 반환합니다. (다음에서 상속됨 Object)
