Paramètres

workflowDefinitionReader

An XmlReader that contains the workflow definition.

rulesReader

An XmlReader.

namedArgumentValues

A Dictionary of objects keyed by string that represents the arguments to the workflow.

Valeur de retour

A WorkflowInstance object that represents the workflow instance created.

Type d'exceptionCondition

ArgumentNullException

workflowDefinitionReader is a null reference (Nothing in Visual Basic).

ObjectDisposedException

The WorkflowRuntime is disposed.

The workflow instance is created from the workflow definition referenced by the XmlReader and the arguments supplied by namedArgumentValues.

Before the WorkflowInstance is created, validation is executed on it. If any validation errors occur, the WorkflowValidationFailedException is thrown. This works well for simple scenarios, but in a server environment, revalidating a workflow for every activation might be unnecessary overhead.

For information about disabling validation, see ValidateOnCreate.

For an example of passing in parameters to CreateWorkflow, see Workflow with Parameters Sample.

For an example of using rules defined in XML, see IfElse with Rules Sample.
