DirectoryPropertyAttribute 类

定义

包含存储区将主体属性映射到目录特性时所需的数据。Contains the data required by the store to map a principal property to a directory attribute. 此特性是主体扩展所必需的,并且只能在属性上设置。This attribute is required for principal extensions and can only be set on a property. 此特性必须在表示扩展类的目录特性的每个属性上指定。It must be specified on every property that represents a directory attribute in the extended class.

public ref class DirectoryPropertyAttribute sealed : Attribute

属性

注解

如果扩展方法中使用了多个目录属性,则应将多个属性添加到属性(每个属性一个)。If multiple directory attributes are used in the extension methods, multiple attributes should be added to the property (one per attribute).

构造函数

DirectoryPropertyAttribute(String)

使用架构特性名称初始化 DirectoryPropertyAttribute 类的新实例。Initializes a new instance of the DirectoryPropertyAttribute class with the schema attribute name.

属性

Context

此属性未实现且始终返回 null。This property is not implemented and always returns null.

SchemaAttributeName

返回表示目录中特性名称的字符串。Returns the string that represents the attribute name in the directory.

TypeId

在派生类中实现时,获取此 Attribute 的唯一标识符。When implemented in a derived class, gets a unique identifier for this Attribute.

(继承自 Attribute)

方法

Equals(Object)

返回一个值,该值指示此实例是否与指定的对象相等。Returns a value that indicates whether this instance is equal to a specified object.

(继承自 Attribute)
GetHashCode()

返回此实例的哈希代码。Returns the hash code for this instance.

(继承自 Attribute)
GetType()

获取当前实例的 TypeGets the Type of the current instance.

(继承自 Object)
IsDefaultAttribute()

在派生类中重写时,指示此实例的值是否是派生类的默认值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.

(继承自 Attribute)
Match(Object)

当在派生类中重写时,返回一个指示此实例是否等于指定对象的值。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.

(继承自 Attribute)
MemberwiseClone()

创建当前 Object 的浅表副本。Creates a shallow copy of the current Object.

(继承自 Object)
ToString()

返回一个表示当前对象的 string。Returns a string that represents the current object.

(继承自 Object)

显式接口实现

_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

将一组名称映射为对应的一组调度标识符。Maps a set of names to a corresponding set of dispatch identifiers.

(继承自 Attribute)
_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

检索对象的类型信息,然后可以使用该信息获取接口的类型信息。Retrieves the type information for an object, which can be used to get the type information for an interface.

(继承自 Attribute)
_Attribute.GetTypeInfoCount(UInt32)

检索对象提供的类型信息接口的数量(0 或 1)。Retrieves the number of type information interfaces that an object provides (either 0 or 1).

(继承自 Attribute)
_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

提供对某一对象公开的属性和方法的访问。Provides access to properties and methods exposed by an object.
