ForLoop Class

Definition

Provides a container that defines an iterative workflow in a package, using the for iteration statement.

public ref class ForLoop sealed : Microsoft::SqlServer::Dts::Runtime::EventsProvider, Microsoft::SqlServer::Dts::Runtime::IDTSExecutionPath, Microsoft::SqlServer::Dts::Runtime::IDTSPackagePath, Microsoft::SqlServer::Dts::Runtime::IDTSPropertiesProvider, Microsoft::SqlServer::Dts::Runtime::IDTSPropertiesProviderEx, Microsoft::SqlServer::Dts::Runtime::IDTSSequence
public sealed class ForLoop : Microsoft.SqlServer.Dts.Runtime.EventsProvider, Microsoft.SqlServer.Dts.Runtime.IDTSExecutionPath, Microsoft.SqlServer.Dts.Runtime.IDTSPackagePath, Microsoft.SqlServer.Dts.Runtime.IDTSPropertiesProvider, Microsoft.SqlServer.Dts.Runtime.IDTSPropertiesProviderEx, Microsoft.SqlServer.Dts.Runtime.IDTSSequence

Remarks

At run time, the control flow in the ForLoop container is repeated within the overall package control flow. In each iteration of the loop, the ForLoop container evaluates an expression and repeats its workflow until the expression evaluates to false. For more information, see For Loop Container.

If the ForceExecutionValue property is set to True, gets or sets a value that specifies the optional execution value that the package returns.

(Inherited from DtsContainer)
ForceExecutionResult

Gets or sets a DTSForcedExecResult enumeration value that specifies the forced execution result of the container.

(Inherited from DtsContainer)
ForceExecutionValue

Methods

AcceptBreakpointManager(BreakpointManager)

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.

(Inherited from DtsContainer)
Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

(Inherited from DtsContainer)
Equals(Object)

Determines whether two object instances are equal.

(Inherited from DtsObject)
Execute(Connections, Variables, IDTSEvents, IDTSLogging, Object)

Runs the application, container, or package as part of a package workflow.

(Inherited from DtsContainer)
GetExecutionPath()

Gets the execution path for the ForLoop object.

GetExpression(String)

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.

(Inherited from DtsObject)
GetPackagePath()

Returns a String that contains the relative path to the package location.

LoadFromXML(XmlNode, IDTSEvents)

This method is not callable by your application code. To load a package saved as .xml, use the LoadPackage(String, IDTSEvents) method.

(Inherited from DtsContainer)
ResumeExecution()

Resumes execution of the task after pausing. The task or container is resumed by the runtime engine.

(Inherited from DtsContainer)
SaveToXML(XmlDocument, XmlNode, IDTSEvents)

This method is not callable by your application code. To save a package as .xml, use the SaveToXml(String, Package, IDTSEvents) method.

(Inherited from DtsContainer)
SetExpression(String, String)

Assigns the specified expression to the property. Specify null to remove an existing expression from the property.

SetWrappedExecutable(IDTSExecutable100)

Returns the wrapped executable object.

(Inherited from EventsProvider)
SuspendExecution()

Called when the executable needs to suspend. This method is called by the runtime engine.

(Inherited from DtsContainer)
Validate(Connections, Variables, IDTSEvents, IDTSLogging)

Allows the container to determine if it contains invalid settings that will prevent it from executing successfully.

(Inherited from DtsContainer)

Events

Disposed

Adds an event handler to listen to the Disposed event on the component.
