建構函式

	名稱	說明
	ConnectionManagerBase	Initializes a new instance of the ConnectionManagerBase class.

屬性

	名稱	說明
	ConnectionString	Gets or sets the connection string for the connection.
	ProtectionLevel	Gets or sets a value, by using the DTSProtectionLevel enumeration, that enforces how the connection controls sensitive information.
	SupportsDTCTransactions	Returns a Boolean that indicates if the connection supports Microsoft Distributed Transaction Coordinator (MS DTC) transactions.
	Version	Returns the version of this connection manager.

方法

	名稱	說明
	AcquireConnection	Creates an instance of the connection type.
	CanUpdate	Gets or sets a Boolean that determines whether a connection manager supports upgrading the connection XML to a newer version.
	Equals	Determines whether two object instances are equal. (繼承自 DtsObject。)
	Finalize	(繼承自 Object。)
	GetHashCode	Returns the hash code for this instance. (繼承自 DtsObject。)
	GetType	(繼承自 Object。)
	MemberwiseClone	(繼承自 Object。)
	ReleaseConnection	Frees the connection established during AcquireConnection. Called at design time and run time.
	SetQualifier	Changes a qualifier on the connection manager after the connection manager has been created, but before it is run.
	ToString	(繼承自 Object。)
	Update	Updates the XML persisted by a previous version of the connection manager.
	Validate	Validates the connection and returns an enumeration that indicates success or failure.

備註

You create a managed connection manager by deriving a managed class from the ConnectionManagerBase, and then marking it with DtsConnectionAttribute attribute.

When creating a managed connection manager, you must ensure that the threading model is Both for the connection manager to work properly with the Integration Services runtime.
