FieldInfo.IsFamily 속성

정의

Family에서 이 필드의 표시 유형을 설명하는지 여부를 나타내는 값을 가져옵니다. 즉, 이 필드는 해당 클래스 및 파생 클래스에만 표시됩니다.Gets a value indicating whether the visibility of this field is described by Family; that is, the field is visible only within its class and derived classes.

public:
 property bool IsFamily { bool get(); };
public bool IsFamily { get; }
member this.IsFamily : bool
Public ReadOnly Property IsFamily As Boolean

속성 값

Family에서 이 필드에 대한 액세스를 정확하게 설명하면 true이고, 그렇지 않으면 false입니다.true if access to this field is exactly described by Family; otherwise, false.

구현

예제

다음 코드 예제에서는 다양 한 수준의 가시성을 사용 하 여 필드를 정의 하 고 값이 표시 됩니다 자신의 IsAssembly, IsFamilyIsFamilyOrAssembly, 및 IsFamilyAndAssembly 속성입니다.The following code example defines fields with varying levels of visibility, and displays the values of their IsAssembly, IsFamily, IsFamilyOrAssembly, and IsFamilyAndAssembly properties.

참고

Visual Basic 및 C# 언어를 사용 하 여 필드를 정의할 수 없습니다 FieldAttributes.FamANDAssem 가시성; 액세스 수준 c + + 예제 나타나도록 합니다.The Visual Basic and C# languages cannot define fields with FieldAttributes.FamANDAssem visibility; that access level appears only in the C++ example.

설명

필드의 표시 유형을 정확 하 게 설명 됩니다 FieldAttributes.Family 만 표시 한정자가 하는 경우 protected합니다.The visibility of a field is exactly described by FieldAttributes.Family if the only visibility modifier is protected. 이 속성은 false 필드에 대 한 protected internal C#에서 (Protected Friend Visual basic에서는 protected public c + +에서); 사용을 IsFamilyOrAssembly 이러한 필드를 식별 하는 속성입니다.This property is false for fields that are protected internal in C# (Protected Friend in Visual Basic, protected public in C++); use the IsFamilyOrAssembly property to identify such fields.
