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

	名稱	說明
	Add	Adds a user-defined function 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 specidied index value.

備註

A UserDefinedFunctionCollection object can be used to gain access to a set of user-defined functions. You can use the Item property to return a specific UserDefinedFunction 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。
