ForeignKeyColumnCollection 类型公开以下成员。

属性

	名称	说明
	Count	Gets the number of objects in the referenced collection. （从 SmoCollectionBase 继承。）
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. （从 SmoCollectionBase 继承。）
	Item[Int32]	Gets a ForeignKeyColumn object in the collection by index number.
	Item[String]	Gets a ForeignKeyColumn object in the collection by name.
	Parent	Gets the ForeignKey object that is the parent of the ForeignKeyColumnCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. （从 SmoCollectionBase 继承。）

注释

A ForeignKeyColumnCollection object can be used to gain access to a set of foreign key columns. You can use the Item property to return a specific ForeignKeyColumn object.
