Свойства

	Имя	Описание
	AssignExpression	Инфраструктура. Gets or sets an expression to increment or decrement the loop counter.
	CreationName	Инфраструктура. Returns the name that is used by the runtime to create an instance of the object and add it to its collection, if there is a collection for the object. This property is read-only.
	DebugMode	Инфраструктура. Gets or sets a Boolean that indicates whether a task should check if breakpoints are enabled.

	Disable	Инфраструктура. Gets or sets a value that indicates whether the IDTSContainer100 object is disabled.
	DisableEventHandlers	Инфраструктура. Gets or sets a Boolean that indicates whether the event handlers on task are disabled.
	EvalExpression	Инфраструктура. Gets or sets the expression that is evaluated on each pass of the loop.
	EventHandlers	Инфраструктура. Returns a collection of event handler objects. This field is read-only.
	EventInfos	Инфраструктура. Returns a collection of IDTSEventInfo100 objects. This field is read-only.
	Executables	Инфраструктура. Returns a collection of executable objects that are processed during the ForLoopClass iteration.
	ExecutionDuration	Инфраструктура. Returns a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only.
	ExecutionResult	Инфраструктура. Gets a value that indicates the success or failure of the execution of the IDTSContainer100 object.
	ExecutionStatus	Инфраструктура. Gets the current status of the execution of the IDTSContainer100 object at the time of the call.
	FailPackageOnFailure	Инфраструктура. Gets or sets a value that indicates whether the package fails when a child container fails.
	FailParentOnFailure	Инфраструктура. Gets or sets a value that indicates whether the parent container fails when a child container fails.
	ForcedExecutionValue	Инфраструктура. When ForceExecutionValue is true, gets or sets a value that specifies the optional execution value that the package returns.
	ForceExecutionResult	Инфраструктура. Gets or sets the forced execution result of the container.
	ForceExecutionValue	Инфраструктура. Gets or sets a value that indicates whether the execution value of the container should be forced to contain a particular value.
	ID	Инфраструктура. Returns a unique ID assigned to the object. This is usually a GUID. This property is read-only.
	IDTSSuspend100_SuspendRequired	Инфраструктура. Gets or sets a Boolean that indicates whether tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
	InitExpression	Инфраструктура. Gets or sets an optional initialization expression.
	IsDefaultLocaleID	Инфраструктура. Gets a value that indicates whether the container uses the default locale.
	IsolationLevel	Инфраструктура. Gets or sets the isolation level of the transaction in the IDTSContainer100 object.
	LocaleID	Инфраструктура. Gets or sets the identifier of the locale to use when the IDTSContainer100 object is executed.
	LogEntryInfos	Инфраструктура. Gets a collection of information about a log entry.
	LoggingMode	Инфраструктура. Gets or sets the logging mode of the container.
	LoggingOptions	Инфраструктура. Gets an object that contains properties that indicates the filtering and logging resource for containers.
	MaximumErrorCount	Инфраструктура. Gets or sets the maximum number of errors that can occur before the container stops running.
	Name	Инфраструктура. Gets or sets a name assigned to the object.
	Parent	Инфраструктура. Gets the parent of the container.
	PrecedenceConstraints	Инфраструктура. Returns a IDTSPrecedenceConstraints100 collection. This field is read-only.
	Properties	Инфраструктура. Returns a set of properties for the ForLoopClass into a IDTSProperties100 collection.
	StartTime	Инфраструктура. Returns the time that the container began execution. This property is read-only.
	StopTime	Инфраструктура. Returns the time that the container ended execution. This property is read-only.
	SuspendRequired	Инфраструктура. Gets or sets a Boolean that indicates whether tasks should suspend when they encounter a breakpoint. This value is set by the runtime engine for tasks and containers when a breakpoint is encountered.
	TransactionOption	Инфраструктура. Gets or sets a DTSTransactionOption enumeration value that indicates whether the container participates in transactions.
	VariableDispenser	Инфраструктура. Gets an IDTSVariableDispenser100 object so variables associated with the container can be locked.
	Variables	Инфраструктура. Gets a collection that contains the variables associated with this container.

Методы

	Имя	Описание
	AcceptBreakpointManager	Инфраструктура. Passes a IDTSBreakpointManager100 to a task. The task will use the breakpoint manager to create, remove, and check the status of breakpoints. This method is called by the runtime and is not used in code.
	ComputeExpressions	Инфраструктура. Computes the expressions of the ForLoopClass object.
	Equals	(Производный от Object.)
	Execute	Инфраструктура. Executes the executable.
	Finalize	(Производный от Object.)
	GetExpression	Инфраструктура. Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	(Производный от Object.)
	GetParentID	Инфраструктура. Gets the parent identifier of this container.
	GetType	(Производный от Object.)
	IDTSForLoop100_Execute	Инфраструктура. Executes the executable.
	IDTSForLoop100_Validate	Инфраструктура. Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
	IDTSSuspend100_ResumeExecution	Инфраструктура. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	IDTSSuspend100_SuspendExecution	Инфраструктура. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	LoadFromXML	Инфраструктура. Loads data stored in XML format.
	MemberwiseClone	(Производный от Object.)
	RegenerateID	Инфраструктура. Creates a new identifier for the container and updates the container identifier.
	ResumeExecution	Инфраструктура. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	Инфраструктура. Saves information to an XML document.
	SetExpression	Инфраструктура. Assigns the specified expression to the property. Specify nullпустая ссылка (Nothing в Visual Basic) to remove an existing expression from the property.
	SuspendExecution	Инфраструктура. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	(Производный от Object.)
	Validate	Инфраструктура. Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
