	EventHandlers	Infrastructure. Gets a collection of event handler objects. This field is read-only.
	EventInfos	Infrastructure. Gets a collection of IDTSEventInfo100 objects. This field is read-only.
	Executables	Infrastructure. Gets a collection of executable objects.
	ExecutionDuration	Infrastructure. Returns a value that indicates the amount of time that the container spent in execution, in milliseconds. This property is read-only.
	ExecutionResult	Infrastructure. Returns a value that indicates the success or failure of the execution of the ForEachLoopClass object.
	ExecutionStatus	Infrastructure. Returns a value that indicates the current status of the execution of the ForEachLoopClass object at the time of the call.
	FailPackageOnFailure	Infrastructure. Gets or sets a Boolean that indicates whether the package fails when a child container fails.
	FailParentOnFailure	Infrastructure. Gets or sets a Boolean that defines whether the parent container fails when a child container fails.
	ForcedExecutionValue	Infrastructure. If the ForceExecutionValue property is set to true, gets or sets a value that specifies the optional execution value that the package returns.
	ForceExecutionResult	Infrastructure. Gets or sets a DTSExecResult enumeration value that specifies the forced execution result of the container.
	ForceExecutionValue	Infrastructure. Gets or sets a Boolean that indicates whether the execution value of the container should be forced to contain a particular value.
	ForEachEnumerator	Infrastructure. Gets or sets a host for the IDTSForEachEnumerator100.
	ID	Infrastructure. Gets the GUID of the ForEachLoopClass. The value is read-only.
	IDTSSuspend100_SuspendRequired	Infrastructure. Gets or sets a Boolean that indicates if 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.
	IsDefaultLocaleID	Infrastructure. A Boolean that indicates whether the container uses the default locale. This property is read-only.
	IsolationLevel	Infrastructure. Gets or sets the isolation level of the transaction in the ForEachLoopClass object.
	LocaleID	Infrastructure. Gets or sets an Integer that indicates the Microsoft Win32® localeID to use when the ForEachLoopClass object is executed.
	LogEntryInfos	Infrastructure. Gets the IDTSLogEntryInfos100 object for the container. This property is read-only.
	LoggingMode	Infrastructure. Gets or sets a valid value from the DTSLoggingMode enumeration that indicates the logging mode of the container.
	LoggingOptions	Infrastructure. Gets an object that contains properties that indicates the filtering and logging resource for containers. This property is read-only.
	MaximumErrorCount	Infrastructure. Gets or sets an Integer value that indicates the maximum number of errors that can occur before the ForEachLoopClass object stops running.
	Name	Infrastructure. Gets or sets the name of the ForEachLoopClass.
	Parent	Infrastructure. Gets the parent container. The value is read-only.
	PrecedenceConstraints	Infrastructure. Gets an IDTSPrecedenceConstraints100 collection that contains all of the precedence constraints associated with the ForEachLoop.
	Properties	Infrastructure. Returns a collection of IDTSProperty100 objects associated with the ForEachLoop.
	StartTime	Infrastructure. Gets the time that the container began execution. This property is read-only.
	StopTime	Infrastructure. Gets the time that the container ended execution. This property is read-only.
	SuspendRequired	Infrastructure. Gets or sets a Boolean that indicates if 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	Infrastructure. Gets or sets a DTSTransactionOption enumeration value that indicates whether the container participates in transactions.
	VariableDispenser	Infrastructure. Gets an IDTSVariableDispenser100 object so variables associated with the container can be locked.
	VariableMappings	Infrastructure. Gets an IDTSForEachVariableMappings100 collection that contains the variable mappings for the ForEachLoop.
	Variables	Infrastructure. Returns a collection that contains the variables associated with this container. This property is read-only.

Méthodes

	Nom	Description
	AcceptBreakpointManager	Infrastructure. Accepts an IDTSBreakpointManager100 manager, that is called by the run-time engine when a task or container is created, 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.
	ComputeExpressions	Infrastructure. Computes the expressions in the property collection.
	Equals	(hérité de Object.)
	Execute	Infrastructure. Executes the executable.
	Finalize	(hérité de Object.)
	GetExpression	Infrastructure. Returns a String that contains the expression for the specified property. Null means no expression is assigned.
	GetHashCode	(hérité de Object.)
	GetParentID	Infrastructure. Gets the ID of the parent container.
	GetType	(hérité de Object.)
	IDTSForEachLoop100_Execute	Infrastructure. Executes the executable.
	IDTSForEachLoop100_Validate	Infrastructure. Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
	IDTSSuspend100_ResumeExecution	Infrastructure. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	IDTSSuspend100_SuspendExecution	Infrastructure. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	LoadFromXML	Infrastructure. Loads data stored in XML format.
	MemberwiseClone	(hérité de Object.)
	RegenerateID	Infrastructure. For more information, see ForEachLoop.
	ResumeExecution	Infrastructure. Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.
	SaveToXML	Infrastructure. Saves information to an XML document.
	SetExpression	Infrastructure. Assigns the specified expression to the property. Specify nullune référence Null (Nothing dans Visual Basic) to remove an existing expression from the property.
	SuspendExecution	Infrastructure. Indicates that the executable needs to suspend. This method is called by the runtime engine.
	ToString	(hérité de Object.)
	Validate	Infrastructure. Verify that the executable will successfully execute by validating all its dependencies and other items before executing it.
