Type.IsNestedFamORAssem Type.IsNestedFamORAssem Type.IsNestedFamORAssem Type.IsNestedFamORAssem Property

Определение

Возвращает значение, позволяющее определить, является ли данный объект Type вложенным и видимым только для классов, принадлежащих либо к его семейству, либо к его сборке.Gets a value indicating whether the Type is nested and visible only to classes that belong to either its own family or to its own assembly.

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

Значение свойства

true Если Type является вложенным и видимым только классам, принадлежащим его семейству или его сборке; в противном случае — false.if the Type is nested and visible only to classes that belong to its own family or to its own assembly; otherwise, false.

Примеры

В следующем примере создается внешнего класса с количеством вложенные классы, которые имеют различные типы видимости.The following example creates an outer class with a number of nested classes that have various types of visibility. Затем извлекается значение из нескольких связанных с видимостью Type свойства для родительского типа и всех его вложенных типов.It then retrieves the value of a number of visibility-related Type properties for the parent type and each of its nested types.

Если видимость типа protected internal в C# или Protected Friend в Visual Basic, IsNestedFamORAssem возвращает true.If the visibility of a type is protected internal in C# or Protected Friend in Visual Basic, the IsNestedFamORAssem property returns true.

Если текущий Type представляет параметр типа универсального типа, это свойство всегда возвращает false.If the current Type represents a type parameter of a generic type, this property always returns false.

TypeAttributes.VisibilityMask выбирает атрибуты видимости.selects the visibility attributes.

Объект Type семейство объекта определяется как все объекты точного же Type и из его подтипов.A Type object's family is defined as all objects of the exact same Type and of its subtypes.
