我如何從ActivityTrackingRecord中讀取添加到我的活動中的屬性

Question

我已將TypeDescriptionProvider添加到我的活動課程中（SequentialWorkflow）。我跟蹤我有​​記錄。記錄有ActivityType和它的屬性，但我看不到我添加的屬性。如何從工作流程追蹤中的TypeDescriptionProvider中讀取價值？

[Browsable(true)] 
[Description("Enter ....")] 
public string Test 
{ 
    get { return ((string)(base.GetValue(YourActivity.TestProperty))); } 
    set { base.SetValue(YourActivity.TestProperty, value); } 
}
