Retrieves the workflow instance that has the specified
Guid.
Namespace: System.Workflow.Runtime
Assembly: System.Workflow.Runtime (in system.workflow.runtime.dll)
Visual Basic (Declaration)
Public Function GetWorkflow ( _
instanceId As Guid _
) As WorkflowInstance
Dim instance As WorkflowRuntime
Dim instanceId As Guid
Dim returnValue As WorkflowInstance
returnValue = instance.GetWorkflow(instanceId)
public WorkflowInstance GetWorkflow (
Guid instanceId
)
public:
WorkflowInstance^ GetWorkflow (
Guid instanceId
)
public WorkflowInstance GetWorkflow (
Guid instanceId
)
public function GetWorkflow (
instanceId : Guid
) : WorkflowInstance
Parameters
- instanceId
The Guid of a workflow instance.
Return Value
The WorkflowInstance that has the specified Guid.
If instanceId specifies a workflow instance that is not currently in memory, the workflow instance is loaded into memory and scheduled for execution. For example, after a workflow instance has been aborted, you can call GetWorkflow to load the workflow instance back into memory. In this case, the last persisted state of the workflow instance will be loaded into memory by the persistence service.
The following code example demonstrates a ReloadWorkflow method that calls the GetWorkflow method. The ReloadWorkflow method is part of a larger class that has a Runtime property to access all of the methods, properties, and events of the WorkflowRuntime class.
This code example is part of the Custom Persistence Service SDK sample from the Program.cs file. For more information, see Custom Persistence Service.

| In the example, the call to Load is redundant because both the GetWorkflow and Load methods use the same internal helper method to load the workflow instance into memory. |
private void ReloadWorkflow(object id)
{
// Reload the workflow so that it will continue processing
this.Runtime.GetWorkflow((Guid)id).Load();
