SqlTrackingWorkflowInstance.WorkflowInstanceId 属性

定义

命名空间:

System.Workflow.Runtime.Tracking

程序集:

System.Workflow.Runtime.dll

为其应用此 Guid 的工作流实例的 SqlTrackingWorkflowInstance。

public:
 property Guid WorkflowInstanceId { Guid get(); void set(Guid value); };

public Guid WorkflowInstanceId { get; set; }

member this.WorkflowInstanceId : Guid with get, set

Public Property WorkflowInstanceId As Guid

属性值

Guid

为其应用此 Guid 的工作流实例的 SqlTrackingWorkflowInstance。

示例

下面的代码示例演示如何获取有关所显示工作流的列表中包含的所有 SqlTrackingWorkflowInstance 对象的信息。 代码为 ListViewItem 变量中的每个 SqlTrackingWorkflowInstance 创建一个 displayedWorkflows。 每个 ListViewItem 都包含 WorkflowInstanceInternalId、WorkflowType 和 Status 属性的字符串表示形式。 然后，它将该项添加到 workflowStatusList。 代码使用以前命名的属性值和 Initialized 属性的字符串版本来创建同样会添加到 WorkflowStatusInfo 的新 workflowStatusList 对象。

static void WriteTerminatedEventArgs(string eventDescription, TrackingWorkflowTerminatedEventArgs terminatedEventArgs, DateTime eventDataTime)
{
    Console.WriteLine("\nTerminated Event Arguments Read From Tracking Database:\n");
    Console.WriteLine("EventDataTime: " + eventDataTime.ToString());
    Console.WriteLine("EventDescription: " + eventDescription);
    if (null != terminatedEventArgs.Exception)
    {
        Console.WriteLine("TerminatedEventArgs Exception Message: " + terminatedEventArgs.Exception.Message.ToString());
    }
}

Shared Sub WriteTerminatedEventArgs(ByVal eventDescription As String, ByVal terminatedEventArgs As TrackingWorkflowTerminatedEventArgs, ByVal eventDataTime As DateTime)
    Console.WriteLine(vbCrLf + "Terminated Event Arguments Read From Tracking Database:")
    Console.WriteLine("EventDataTime: " + eventDataTime.ToString(CultureInfo.CurrentCulture))
    Console.WriteLine("EventDescription: " + eventDescription)
    If terminatedEventArgs.Exception IsNot Nothing Then
        Console.WriteLine("TerminatedEventArgs Exception Message: " + terminatedEventArgs.Exception.Message.ToString())
    End If
End Sub
