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 UserDefinedAggregate object in the collection by index number.
	Item[String]	Gets a UserDefinedAggregate object in the collection by name.
	Item[String, String]	Gets a UserDefinedAggregate object in the collection by name and schema.
	Parent	Gets the Database object that is the parent of the UserDefinedAggregate object.
	SyncRoot	Gets an object that can be used to synchronize access to the collection. (繼承自 SmoCollectionBase。)

方法

	名稱	說明
	Add	Adds a user-defined aggregate to the collection.
	AddExisting	Adds an object to the collection. (繼承自 AbstractCollectionBase。)
	Contains(String)	Validates whether the parameter collection contains a member with a name equal to the specified string. (繼承自 SchemaCollectionBase。)
	Contains(String, String)	Validates whether the parameter collection contains a member with a name equal to the specified string and with the specified schema. (繼承自 SchemaCollectionBase。)
	CopyTo	Copies the collection objects to a one-dimensional array starting at the specified index value.
	Equals	(繼承自 Object。)

備註

A UserDefinedAggregateCollection object can be used to gain access to a set of database user-defined aggregates. You can use the Item property to return a specific UserDefinedAggregate 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。
