定义

注意

This attribute is no longer in use and will be ignored if applied.

指定实体成员表示数据关系(如外键关系)。Specifies that an entity member represents a data relationship, such as a foreign key relationship.

属性

构造函数

AssociationAttribute(String, String, String)

初始化 AssociationAttribute 类的新实例。Initializes a new instance of the AssociationAttribute class.

属性

IsForeignKey

获取或设置一个值,该值指示关联成员是否表示一个外键。Gets or sets a value that indicates whether the association member represents a foreign key.

Name

获取关联的名称。Gets the name of the association.

OtherKey

获取关联的 OtherKey 端的键值的属性名称。Gets the property names of the key values on the OtherKey side of the association.

OtherKeyMembers

获取在 OtherKey 属性中指定的各个键成员的集合。Gets a collection of individual key members that are specified in the OtherKey property.

ThisKey

获取关联的 ThisKey 端的键值的属性名称。Gets the property names of the key values on the ThisKey side of the association.

ThisKeyMembers

获取在 ThisKey 属性中指定的各个键成员的集合。Gets a collection of individual key members that are specified in the ThisKey property.

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()

返回表示当前对象的字符串。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.
