WorkflowRuntime.CreateWorkflow Method (Type, Dictionary<String, Object>)

Namespace:   System.Workflow.Runtime
Assembly:  System.Workflow.Runtime (in System.Workflow.Runtime.dll)

public WorkflowInstance CreateWorkflow(
	Type workflowType,
	Dictionary<string, object> namedArgumentValues


Type: System.Type

The Type of the workflow to create.

Type: System.Collections.Generic.Dictionary<String, Object>

A Dictionary<TKey, TValue> of objects keyed by string that represents the arguments to the workflow.

Return Value

Type: System.Workflow.Runtime.WorkflowInstance

The created workflow instance.

Exception Condition

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

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 more information about disabling validation, see ValidateOnCreate.

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