WorkflowInstance.Suspend Method

Suspends the workflow instance.

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

public void Suspend(
	string error


Type: System.String

A description of the reason for suspending the workflow instance.


The workflow runtime engine is not running.

The workflow instance is suspended in a synchronous manner. If the workflow instance is already suspended, no action is taken; otherwise, the workflow runtime engine suspends the workflow instance, raises the WorkflowSuspended event and passes reason in a WorkflowSuspendedEventArgs.


Suspend does not unload the workflow instance.

The following code example demonstrates calling Suspend on a WorkflowInstance object.

// Create a workflow runtime
WorkflowRuntime workflowRuntime = new WorkflowRuntime();
// Create a workflow instance
WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(typeof(Workflow1));
// Start the workflow
// Suspend the workflow, passing in a message
workflowInstance.Suspend("Workflow manually suspended");
