ConnectionManagerBase 类型公开以下成员。

构造函数

	名称	说明
	ConnectionManagerBase	Initializes a new instance of the ConnectionManagerBase class.

属性

	名称	说明
	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.
	Scope	Gets the DTS connection manager scope for this ConnectionManagerBase object.
	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

	名称	说明
	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. （从 DtsObject 继承。）
	Finalize	（从 Object 继承。）
	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	MemberwiseClone	（从 Object 继承。）
	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	（从 Object 继承。）
	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.

注释

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.

线程安全

此类型的任何公共 static（在 Visual Basic 中为 Shared） 成员都是线程安全的。不保证所有实例成员都是线程安全的。
