我在容器中注册了一堆TaskParametes类实例,如:

builder.Register(c => [some type instantiation]
    )).Named<TaskParameters>("someTask").InstancePerDependency();

builder.Register(c => [some type instantiation]
    )).Named<TaskParameters>("someOtherTask").InstancePerDependency();

这些类可以在应用程序的任何模块中注册.我想获取可用的命名实例列表以将其发送到客户端,客户端应该按名称实例化并执行它.

是否有选项可以获取名称列表,而无需实际实例化类型？目前我正在挖掘IComponentContext的ComponentRegistry,我得到了,var ctx = Container.Resolve<IComponentContext>();我是否朝着正确的方向前进？

我在MassTransit中完成了一个简单的发布者.我正在间隔发送消息,并且能够使用MassTransit从.NET客户端接收消息.但是当我尝试从Python中观察某些东西时,它是沉默的.有没有办法从Python或其他语言中使用MassTransit？举例赞赏.

出版商:

builder.Register(c => ServiceBusFactory.New(sbc => {
    sbc.UseRabbitMq();
    sbc.UseBsonSerializer();
    sbc.UseLog4Net();

    sbc.ReceiveFrom("rabbitmq://localhost/masstransit");
});

.NET客户端:

public void Execute(IJobExecutionContext context) {
   using (var scope = ServiceLocator.Current.GetInstance<ILifetimeScope>().BeginLifetimeScope()) {
       var log = scope.Resolve<ILog>();
       log.Debug("Sending queue message");

       var bus = scope.Resolve<IServiceBus>();
       bus.Publish(new SimpleTextMessage{Text = "some text"});
   }
}

Python客户端:

import pika
print('Stating consumer')
connection = pika.BlockingConnection(pika.ConnectionParameters(
    host='localhost'))
channel = connection.channel()

channel.queue_declare(queue='python_consumer_1')

print ' [*] Waiting for messages. To exit press CTRL+C'

def callback(ch, method, properties, body):
    print " [x] Received %r" % (body,)

channel.basic_consume(callback, queue='python_consumer_1')
channel.start_consuming() …

通常我有以下情况:有一个PONO类,其中包含属性列表.

    public string UserName
    {
        get { return this.userName; }
        set { if (this.userName != value) { SetDirty(); this.userName = value; } }
    }

    public string Password
    {
        get { return this.password; }
        set { if (this.password != value) { SetDirty(); this.password = value; } }
    }

    public string Email
    {
        get { return this.email; }
        set { if (this.email != value) { SetDirty(); this.email = value; } }
    }

    public string Title
    {
        get { return this.title; }
        set …

安装了Roslyn,玩:C:\ Users \name\Documents\Microsoft Codename Roslyn CTP - 2011年10月\ CSharp\WpfSeedRepl演练:http://msdn.microsoft.com/ru-ru/hh543924.

我无法加载当前的DLL和csx:

> #r "wpfseed.exe"
(1,1): error CS0006: Metadata file 'wpfseed.exe' could not be found

> #load "setup.csx"
Specified file not found.
Searched in directory:
  C:\Users\name

在另一方面:

> Console.WriteLine(Environment.CurrentDirectory);
C:\Users\name\Documents\Microsoft Codename Roslyn CTP - October 2011\CSharp\WpfSeedRepl

是否有任何解决方法不指定项目文件夹？

似乎Monitor在WinRT商店应用程序中无法正常工作.我有以下代码:

protected override void OnNavigatedTo(NavigationEventArgs e)
    {
        var tasks = Enumerable.Range(0, 10).Select((i)=>new Task(DoWork)).ToArray();
        foreach (var task in tasks)
        {
            task.Start();
        }

        Task.WaitAll(tasks);
    }

    static object lockObject = new Object();//typeof(MainPage)

    protected async void DoWork()
    {
        bool taken =false;
        Monitor.Enter(lockObject, ref taken);
        Debug.WriteLine("In");
        await Task.Delay(1000);
        Debug.WriteLine("Out");
        if (taken) Monitor.Exit(lockObject);
    }

在输出窗口中,我看到:

In

In
In

A first chance exception of type 'System.Threading.SynchronizationLockException' occurred in App4.exe

这意味着Monitor没有锁定关键区域.有没有人知道我做错了什么？
