	DestinationDatabaseName	Gets or sets a String containing the name of the database at the destination.
	DestinationOverwrite	Gets or sets a Boolean indicating whether the destination database can be overwritten if it exists.
	ExecutionValue	Returns the result of the task execution. （覆盖 Task.ExecutionValue。）
	Method	Gets or sets a value from the TransferMethod enumeration indicating whether to use Online or Offline transfer method.
	ReattachSourceDatabase	A Boolean indicating whether the database should be reattached or not.

方法

	名称	说明
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. （从 Task 继承。）
	Equals	Determines whether two object instances are equal. （从 DtsObject 继承。）
	Execute	Runs the task. （覆盖 Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)。）
	GetConnectionID	Gets a String containing the ID of the connection. （从 Task 继承。）

	GetHashCode	Returns the hash code for this instance. （从 DtsObject 继承。）
	GetType	（从 Object 继承。）
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. （覆盖 Task.InitializeTask(Connections, VariableDispenser, IDTSInfoEvents, IDTSLogging, EventInfos, LogEntryInfos, ObjectReferenceTracker)。）
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application.LoadPackage method.
