MemberInfo.DeclaringType 속성

정의

이 멤버를 선언하는 클래스를 가져옵니다.Gets the class that declares this member.

public:
 abstract property Type ^ DeclaringType { Type ^ get(); };
public abstract Type DeclaringType { get; }
member this.DeclaringType : Type
Public MustOverride ReadOnly Property DeclaringType As Type

속성 값

이 멤버를 선언하는 클래스에 대한 Type 개체입니다.The Type object for the class that declares this member.

구현

예제

다음 예제에서는 GetValue단일 멤버를 사용 하 여 IValue인터페이스를 정의 합니다.The following example defines an interface, IValue, with a single member, GetValue. 또한 IValue 인터페이스를 구현 하는 기본 클래스인 A4 개 클래스를 정의 합니다. BA에서 상속 되며 기본 클래스 구현에서 GetValue의 구현을 숨깁니다. C``A에서 상속 됩니다. 및 D``A에서 상속 되 고 GetValue 메서드를 재정의 합니다.It also defines four classes: A, a base class that implements the IValue interface; B, which inherits from A and hides its implementation of GetValue from the base class implementation; C, which simply inherits from A; and D, which inherits from A and overrides its GetValue method. 그런 다음이 예제에서는 Object에서 상속 된 멤버를 포함 하 여 형식의 각 멤버에 대 한 MemberInfo 개체를 검색 하 고 해당 DeclaringType 속성의 값을 표시 합니다.The example then retrieves a MemberInfo object for each member of the type (including members inherited from Object) and displays the value of its DeclaringType property.

A.GetValue 선언 형식은 B A입니다. 여기에는 A에 의해 선언 되는 GetValue 메서드 두 개와 B의 선언 형식이 D.GetValue 됩니다.DNote that the declaring type of A.GetValue is A, that B includes two GetValue methods, one declared by A and one by B, and that the declaring type of D.GetValue is D.

참고

DeclaringType는 멤버 이름과 해당 선언 형식의 이름만 반환 합니다.DeclaringType returns only the member names and the names of their declaring types. 멤버 이름을 프로토타입으로 반환 하려면 MemberInfo.ToString를 호출 합니다.To return the member names with their prototypes, call MemberInfo.ToString.

설명

DeclaringType 속성은이 멤버를 선언 하는 형식에 대 한 Type 개체에 대 한 참조를 검색 합니다.The DeclaringType property retrieves a reference to the Type object for the type that declares this member. 형식의 멤버는 형식에 의해 선언 되거나 기본 형식에서 상속 됩니다. 따라서 DeclaringType 속성이 반환 하는 Type 개체는 현재 MemberInfo 개체를 가져오는 데 사용 되는 Type 개체와 다를 수 있습니다.A member of a type is either declared by the type or inherited from a base type, so the Type object returned by the DeclaringType property might not be the same as the Type object used to obtain the current MemberInfo object.

  • MemberInfo 개체가 가져온 Type 개체가이 멤버를 선언 하지 않은 경우 DeclaringType 속성은 해당 기본 형식 중 하나를 나타냅니다.If the Type object from which this MemberInfo object was obtained did not declare this member, the DeclaringType property will represent one of its base types.

  • MemberInfo 개체가 전역 멤버인 경우 (즉, 모듈의 전역 메서드를 반환 하는 Module.GetMethods 메서드에서 가져온 경우) 반환 된 DeclaringType null됩니다.If the MemberInfo object is a global member (that is, if it was obtained from the Module.GetMethods method, which returns global methods on a module), the returned DeclaringType will be null.
