설명

CodeCatchClause 는 문의 예외 블록을 나타내는 catch 데 사용할 수 있습니다 try/catch .

속성은 CatchExceptionType catch할 예외의 형식을 지정합니다. 속성은 LocalName catch된 예외를 나타내는 변수의 이름을 지정합니다. 컬렉션 속성에는 Statements 블록에 대한 catch 문이 포함됩니다.

생성자

CodeCatchClause()	CodeCatchClause 클래스의 새 인스턴스를 초기화합니다.
CodeCatchClause(String)	예외에 대해 지정된 지역 변수 이름을 사용하여 CodeCatchClause 클래스의 새 인스턴스를 초기화합니다.
CodeCatchClause(String, CodeTypeReference)	예외 및 예외 형식에 대해 지정된 지역 변수 이름을 사용하여 CodeCatchClause 클래스의 새 인스턴스를 초기화합니다.
CodeCatchClause(String, CodeTypeReference, CodeStatement[])	지정된 예외 형식, 예외의 지역 변수 이름 및 문 컬렉션을 사용하여 CodeCatchClause 클래스의 새 인스턴스를 초기화합니다.

속성

CatchExceptionType	catch 블록으로 처리할 예외의 형식을 가져오거나 설정합니다.
LocalName	catch 절에서 처리하는 예외의 변수 이름을 가져오거나 설정합니다.
Statements	catch 블록에서 문을 가져옵니다.

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)
