建構函式
AssociationAttribute(String, String, String) |
初始化 AssociationAttribute 類別的新執行個體。Initializes a new instance of the AssociationAttribute class. |
屬性
IsForeignKey |
取得或設定值,這個值表示關聯成員是否代表外部索引鍵。Gets or sets a value that indicates whether the association member represents a foreign key. |
Name |
取得關聯的名稱。Gets the name of the association. |
OtherKey |
從關聯的 OtherKey 一端,取得索引鍵值的屬性名稱。Gets the property names of the key values on the OtherKey side of the association. |
OtherKeyMembers |
取得 OtherKey 屬性中所指定個別索引鍵成員的集合。Gets a collection of individual key members that are specified in the OtherKey property. |
ThisKey |
從關聯的 ThisKey 一端,取得索引鍵值的屬性名稱。Gets the property names of the key values on the ThisKey side of the association. |
ThisKeyMembers |
取得 ThisKey 屬性中所指定個別索引鍵成員的集合。Gets a collection of individual key members that are specified in the ThisKey property. |
TypeId |
在衍生類別中實作時,取得這個 Attribute 的唯一識別碼。When implemented in a derived class, gets a unique identifier for this Attribute. (繼承來源 Attribute) |
方法
Equals(Object) |
傳回值,這個值指出此執行個體是否與指定的物件相等。Returns a value that indicates whether this instance is equal to a specified object. (繼承來源 Attribute) |
GetHashCode() |
傳回這個執行個體的雜湊碼。Returns the hash code for this instance. (繼承來源 Attribute) |

IsDefaultAttribute() |
在衍生類別中覆寫時,表示這個執行個體的值是衍生類別的預設值。When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (繼承來源 Attribute) |
Match(Object) |
在衍生類別中覆寫時,會傳回值,表示這個執行個體是否等於指定物件。When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (繼承來源 Attribute) |
