[英]Windows Workflow and Thread.CurrentPrincipal
我遇到Thread.CurrentPrincipal没有从主线程传播到工作流应用程序的问题。
反正有没有这样做?
这是我的示例应用程序:
class Program
{
static void Main(string[] args)
{
Thread.CurrentPrincipal = new GenericPrincipal(new GenericIdentity("Bob", "Passport"), new string[] { "managers", "executives" });
System.Console.WriteLine("MainThread Prinicipal type: " + Thread.CurrentPrincipal.GetType().ToString());
System.Console.WriteLine("MainThread Prinicipal Identity: " + Thread.CurrentPrincipal.Identity.Name);
System.Console.WriteLine();
AutoResetEvent syncEvent = new AutoResetEvent(false);
WorkflowApplication application = new WorkflowApplication(new Workflow1());
application.Completed = delegate(WorkflowApplicationCompletedEventArgs e)
{
syncEvent.Set();
};
application.Run();
syncEvent.WaitOne();
}
}
和工作流程
<Activity mc:Ignorable="sap" x:Class="WorkflowConsoleApplication1.Workflow1" sap:VirtualizedContainerService.HintSize="273,427" mva:VisualBasic.Settings="Assembly references and imported namespaces for internal implementation" xmlns="http://schemas.microsoft.com/netfx/2009/xaml/activities" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:mv="clr-namespace:Microsoft.VisualBasic;assembly=System" xmlns:mva="clr-namespace:Microsoft.VisualBasic.Activities;assembly=System.Activities" xmlns:s="clr-namespace:System;assembly=mscorlib" xmlns:s1="clr-namespace:System;assembly=System" xmlns:s2="clr-namespace:System;assembly=System.Xml" xmlns:s3="clr-namespace:System;assembly=System.Core" xmlns:s4="clr-namespace:System;assembly=System.ServiceModel" xmlns:sad="clr-namespace:System.Activities.Debugger;assembly=System.Activities" xmlns:sap="http://schemas.microsoft.com/netfx/2009/xaml/activities/presentation" xmlns:scg="clr-namespace:System.Collections.Generic;assembly=System" xmlns:scg1="clr-namespace:System.Collections.Generic;assembly=System.ServiceModel" xmlns:scg2="clr-namespace:System.Collections.Generic;assembly=System.Core" xmlns:scg3="clr-namespace:System.Collections.Generic;assembly=mscorlib" xmlns:sd="clr-namespace:System.Data;assembly=System.Data" xmlns:sl="clr-namespace:System.Linq;assembly=System.Core" xmlns:st="clr-namespace:System.Threading;assembly=System.Core" xmlns:st1="clr-namespace:System.Threading;assembly=System" xmlns:st2="clr-namespace:System.Text;assembly=mscorlib" xmlns:st3="clr-namespace:System.Threading;assembly=mscorlib" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Sequence sad:XamlDebuggerXmlReader.FileName="C:\projects\WorkflowConsoleApplication1\WorkflowConsoleApplication1\Workflow1.xaml" sap:VirtualizedContainerService.HintSize="233,387">
<WriteLine sap:VirtualizedContainerService.HintSize="211,61" Text="["WorkflowThread Prinicipal type: " + System.Threading.Thread.CurrentPrincipal.GetType().ToString()]" />
<WriteLine sap:VirtualizedContainerService.HintSize="211,61" Text="["WorkflowThread Prinicipal Identity: " + System.Threading.Thread.CurrentPrincipal.Identity.Name]" />
<WriteLine sap:VirtualizedContainerService.HintSize="211,61" />
</Sequence>
</Activity>
上述程序的输出是:
MainThread Prinicipal类型:System.Security.Principal.GenericPrincipal
MainThread主要身份:BobWorkflowThread Prinicipal类型:System.Security.Principal.GenericPrincipal
WorkflowThread主要标识:
任何帮助将不胜感激。
谢谢
我相信,由于Workflow
在ThreadPool
上运行,因此它们不会继承您在主线程上设置的任何主体。 您可以尝试更改AppDomain
的主体 :
// per MSDN: Create a principal to use for new threads.
IPrincipal principal = new GenericPrincipal(
new GenericIdentity("Bob", "Passport"),
new string[] { "managers", "executives" });
AppDomain.CurrentDomain.SetThreadPrincipal(principal);
WorkflowApplication
使用其SynchronizationContext
来安排实际工作。 默认实现使用ThreadPool 作为user7116描述 。 但是,您可以自由地实现自己的SynchronizationContext
并实现Post()
操作来执行您想要的任何操作。
