WCF关闭连接/解除资源 [英] WCF Closing a connection/Releasing resources

问题描述

我最近将我的ASMX服务，WCF拿会话优势。

I've recently converted my ASMX service to WCF to take advantage of Sessions.

我查看了一些MSDN上的会话教程，但仍然不知道我有我的code一个很好的设置。截至目前它的工作原理，但我真的不知道为什么。

I've reviewed some of the Sessions tutorials on MSDN but still not sure I have a good setup in my code. as of now it works, but I'm not really sure why.

我

[ServiceContract
    (SessionMode = SessionMode.Required,
     Namespace = "http://smartshopservice.org")]

然后，我有

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerSession)]
public class SmartShopService : SmartShopInterface
{
    private static Shopper sh = new Shopper();
    private List<aaa> data = new List<aaa>();

我的问题的第一部分是购物者是否是我的全局变量。我希望它一直在那里，而其他的都是诸如数据每个会话实例化。我还设置appropiately WebConfig。还有什么我需要做什么？

The first part of my question is whether Shopper is my "global" variables. I want it to always be there, while everything else such as "data" is instanciated per session. I've also setup WebConfig appropiately. Is there anything else I need to do?

我的第二个问题是如何关闭会话，并随后把所有这些变量？我的客户，现在是Web客户端，它是这样的沟通：

My second question is how to close a session, and then flush all these variables? My Client right now is a WebClient, it is communicating like this:

static GarfieldService.SmartShopInterfaceClient service 
    = new GarfieldService.SmartShopInterfaceClient();

这似乎工作，我有onbody = ASP.NET页的地叫，看起来像这样的功能：

It seems to work, and I have onbody="" of the ASP.NET page to call a function that looks like this:

[WebMethod]
public static bool Connect() {
    try {
        if (service.State 
            == System.ServiceModel.CommunicationState.Closed) {
            service.Open();
            return true;
        }
        else if (service.State 
            == System.ServiceModel.CommunicationState.Created) {
            service.Open();
            return true;
        }
    }
    catch {}
    return false;
}

所以我可以连接，但我怎么断开连接或关闭会话？

So I can connect, but how do I disconnect or close a session?

推荐答案

回复：全局，是使用静态的服务将作为一个全球性的，因为你使用的是PerSession的AAAvarible将以每股sesssion

Re: Globals, yes using a static on the service will act as a global, and because you are using a PerSession the "aaa" varible will be per sesssion.

回复：终止，尝试创建一个终止的操作和设置属性参数<一个href=\"http://msdn.microsoft.com/en-us/library/system.servicemodel.operationcontractattribute.isterminating.aspx\"相对=nofollow> IsTerminating =真。

Re: terminating, try creating a "terminate" operation and setting attribute parameter IsTerminating = true.

P.S。我不认为WebGet属性是相关的wsDualHttpBinding。

P.S. I dont think the WebGet attribute is relevant to the wsDualHttpBinding.
