How can I run the code in the constructor of a WCF Service only once when the ServiceBehaviorAttribute.InstanceContextMode is set to PerSession?

[ServiceBehavior(
    InstanceContextMode = InstanceContextMode.PerSession, 
    ConcurrencyMode = ConcurrencyMode.Single)]
public class SomeService : ISomeService
{
    public SomeService()
    {
        this.RunThisOnceForAllClients();
    }

    private void RunThisOnceForAllClients() { }
}

或者，我怎么能在运行后自动WCF服务的方法运行，但它的只是将所有客户端上运行，一旦调用

请帮忙。先谢谢了。

^{I deploy my WCF Service using a Managed Windows Service. My code is in C#. Framework is in .NET 4. Project is build in Visual Stuido 2010 Professional. The service is consumed by a Windows Forms Application. In case you wonder on why do I need to do it like this, I need to execute an Uploader method that will upload the database of the service to another service, but it will be executed in a certain time so I put it in another thread that will always run as long as the service is running.}

推荐答案

为什么不执行此操作，在Windows服务承载WCF服务之前，因此它可以准备好，一旦WCF服务上线。您可以从运行不可能得到自己完成线程的事件，然后部署WCF服务。

Why not run this operation just before you host the WCF Service in your windows service so it can be ready as soon as the WCF Service goes online. You can get from the running thread an event that it is finished and then deploy the WCF Service.
