	FailParentOnFailure	Gets or sets a Boolean that defines whether the parent container fails when a child container fails. (Herdado de DtsContainer.)
	ForcedExecutionValue	If the ForceExecutionValue property is set to true, gets or sets a value that specifies the optional execution value that the package returns. (Herdado de DtsContainer.)
	ForceExecutionResult	Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container. (Herdado de DtsContainer.)
	ForceExecutionValue	Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value. (Herdado de DtsContainer.)
	ForEachEnumerator	Gets or sets a host for the ForEachEnumerator.
	ID	Returns the ID, which is a GUID, of the DtsContainer. The value is read-only. (Herdado de DtsContainer.)

	MaximumErrorCount	Gets or sets an Integer value that indicates the maximum number of errors that can occur before the DtsContainer object stops running. (Herdado de DtsContainer.)
	Name	Gets or sets the name of the DtsContainer. (Herdado de DtsContainer.)
	Parent	Returns the parent container. The value is read-only. (Herdado de DtsContainer.)
	PrecedenceConstraints	Returns a PrecedenceConstraints collection that contains all of the precedence constraints associated with the ForEachLoop.

Métodos

	Nome	Descrição
	AcceptBreakpointManager	This method is called by the run-time engine when a task or container is created, and passes it a BreakpointManager manager to allow the task to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code. (Herdado de DtsContainer.)
	Dispose	Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources. (Herdado de DtsContainer.)
	Equals	Determines whether two object instances are equal. (Herdado de DtsObject.)
	Execute	Runs the application, container, or package as part of a package workflow. (Herdado de DtsContainer.)
	Finalize	(Herdado de Object.)
	GetExpression	Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	Returns the hash code for this instance. (Herdado de DtsObject.)
	GetPackagePath	Returns a String that contains the relative path to the package location.
	GetType	(Herdado de Object.)
	LoadFromXML	This method is not callable by your application code. To load a package saved as .xml, use the Application..::..LoadPackage method. (Herdado de DtsContainer.)
	MemberwiseClone	(Herdado de Object.)
	ResumeExecution	Resumes execution of the task after pausing. The task or container is resumed by the runtime engine. (Herdado de DtsContainer.)
	SaveToXML	This method is not callable by your application code. To save a package as .xml, use the Application..::..SaveToXml method. (Herdado de DtsContainer.)
	SetExpression	Assigns the specified expression to the property. Specify nullNothingnullptrunituma referência nula (Nothing no Visual Basic) to remove an existing expression from the property.
	SetWrappedExecutable	Infraestrutura. (Herdado de EventsProvider.)
	SuspendExecution	Called when the executable needs to suspend. This method is called by the runtime engine. (Herdado de DtsContainer.)
	ToString	(Herdado de Object.)
	Validate	Allows the container to determine if it contains invalid settings that will prevent it from executing successfully. (Herdado de DtsContainer.)

Eventos

	Nome	Descrição
	Disposed	Adds an event handler to listen to the Disposed event on the component. (Herdado de DtsContainer.)
