WorkflowChanges Class

Represents a set of proposed changes to a running workflow instance.

Namespace: System.Workflow.ComponentModel
Assembly: System.Workflow.ComponentModel (in system.workflow.componentmodel.dll)

public sealed class WorkflowChanges
public final class WorkflowChanges
public final class WorkflowChanges
Not applicable.

All proposed changes to a running workflow instance must be made using a WorkflowChanges object.

When a WorkflowChanges object is constructed in application code (outside the workflow instance), the Activity object that is passed to the constructor must be the object that is returned by the GetWorkflowDefinition method of the WorkflowInstance class.

The following example demonstrates creating a new instance of a WorkflowChanges object. This example is from the Ordering State Machine SDK sample. For more information, see Ordering State Machine Sample.

// Create a new instance of the WorkflowChanges class for managing
// the in-memory changes to the workflow
WorkflowChanges changes = new WorkflowChanges(root);

System.Object
  System.Workflow.ComponentModel.WorkflowChanges
