	AcceptBreakpointManager	Called by the run-time engine when a task or container is created, and is passed a BreakpointManager to enable the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code.
	CanUpdate	*** Member deprecated; see Remarks. ***    A Boolean that indicates whether the new package XML can update the old package XML. (Task에서 상속됨)
	Equals	Determines whether two object instances are equal. (DtsObject에서 상속됨)
	Execute	Runs the task. (Task.Execute(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging, Object)을(를) 재정의함)
	Finalize	(Object에서 상속됨)
	GetConnectionID	Gets a String containing the ID of the connection. (Task에서 상속됨)
	GetConnectionName	Gets a String containing the name of the connection. (Task에서 상속됨)
	GetHashCode	Returns the hash code for this instance. (DtsObject에서 상속됨)
	GetType	(Object에서 상속됨)
	InitializeTask	Initializes the properties associated with the task. This method is called by the runtime and is not used in code. (Task에서 상속됨)
	LoadFromXML	Loads the definition of the task, in XML format, from the XML definition of the package.
	MemberwiseClone	(Object에서 상속됨)
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	Saves the definition of the task, in XML format, into the XML definition of the package.
	SuspendExecution	Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	(Object에서 상속됨)
	Update	*** Member deprecated; see Remarks. ***    This method updates the old package XML with the new package XML if CanUpdate is set to true. (Task에서 상속됨)
	Validate	Verifies that the task is properly configured. (Task.Validate(Connections, VariableDispenser, IDTSComponentEvents, IDTSLogging)을(를) 재정의함)
	ValidateExpression	Verifies that the expression is properly configured.
