Type.IsPrimitiveImpl 메서드

정의

파생 클래스에서 재정의되면, IsPrimitive 속성을 구현하고 Type이 기본 형식 중 하나인지를 확인합니다.When overridden in a derived class, implements the IsPrimitive property and determines whether the Type is one of the primitive types.

protected:
 abstract bool IsPrimitiveImpl();
protected abstract bool IsPrimitiveImpl ();
abstract member IsPrimitiveImpl : unit -> bool
Protected MustOverride Function IsPrimitiveImpl () As Boolean

반환

Boolean

true이 기본 형식 중 하나이면 Type이고, 그렇지 않으면 false입니다.true if the Type is one of the primitive types; otherwise, false.

예제

다음 예에서는 지정 된 형식이 기본 형식 인지 여부를 확인 하 고 결과를 표시 합니다.The following example determines whether the given type is a primitive type and displays the result.
