ColumnCollection 型別公開下列成員。

屬性

	名稱	說明
	Count	Gets the number of objects in the referenced collection. (繼承自 SmoCollectionBase。)
	IsSynchronized	Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (繼承自 SmoCollectionBase。)
	Item[Int32]	Gets a Column object in the collection by index number.
	Item[String]	Gets a Column object in the collection by name.
	Parent	Gets the SqlSmoObject object that is the parent of the ColumnCollection object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (繼承自 SmoCollectionBase。)

備註

A ColumnCollection object can be used to gain access to a set of columns. You can use the Item property to return a specific Column object.

Thread Safety

此型別的任何公用靜態 (在 Microsoft Visual Basic 為共用) 成員具備多執行緒作業安全。並非所有的執行個體成員都是安全執行緒。
