WorkflowRuntime::CreateWorkflow Method (Type^)

 

Creates a new workflow instance by using the specified workflow Type.

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

public:
WorkflowInstance^ CreateWorkflow(
	Type^ workflowType
)

Parameters

workflowType
Type: System::Type^

The Type of the workflow to create.

Return Value

Type: System.Workflow.Runtime::WorkflowInstance^

The created workflow instance.

Exception Condition
ArgumentNullException

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.

The following code example demonstrates the recommended way to create a WorkflowInstance object in a workflow host using the CreateWorkflow method.

This code example is part of the Canceling a Workflow sample.
