我开发了一个调用 Web 服务的小型 C# 表单应用程序。一切正常，但我需要保持状态，如果我没记错的话，我需要使用 CookieContainer。

我使用项目的“添加服务参考”菜单创建了服务参考，一切运行良好。但我不知道如何在创建的客户端上添加 CookieManager。

我发现了一些显示示例的示例，例如：

serviceClient.CookieContainer=new CookieContainer()

但这种情况并非如此。我的服务客户端没有这样的属性。顺便说一句，我正在起诉 Visual Studio 2010 Beta。

先感谢您！

这是生成的 ServiceReference（它是自动创建的）：

当您可以在绑定上启用 cookie 时，为什么要恢复使用旧技术？

引用：如果 XML Web 服务方法使用会话状态，那么 cookie 会在响应标头中传递回 XML Web 服务客户端，该客户端唯一地标识该 XML Web 服务客户端的会话。为了让 XML Web services 为客户端维护会话状态，客户端必须存储 cookie。

上面的答案只有一个非常有用的文章的链接，但它没有其他详细信息
链接唯一的答案在 StackOverflow 上不是首选，因此这里是该文章的摘要

这是文章中的罪过

在 WCF 世界中，情况有些不同。WCF 是一种与传输无关的技术，它不允许 cookie 的概念直接反映在高级 API 中，因为它特定于 HTTP 协议。这实际上转化为没有任何 CookieContainer 属性要设置和检索的 Web 服务客户端对象。

这是 WCF 的解决方案（也适用于我）

private static void Main(object[] args)
{
    string sharedCookie;

    MyWebServiceClient client = new MyWebServiceClient();

    using (new OperationContextScope(client.InnerChannel))
    {
        client.DoSomething();

        // Extract the cookie embedded in the received web service response
        // and stores it locally
        HttpResponseMessageProperty response = (HttpResponseMessageProperty)
        OperationContext.Current.IncomingMessageProperties[
            HttpResponseMessageProperty.Name];
        sharedCookie = response.Headers["Set-Cookie"];
    }

    MyOtherWebServiceClient otherClient = new MyOtherWebServiceClient();

    using (new OperationContextScope(otherClient.InnerChannel))
    {
        // Embeds the extracted cookie in the next web service request
        // Note that we manually have to create the request object since
        // since it doesn't exist yet at this stage
        HttpRequestMessageProperty request = new HttpRequestMessageProperty();
        request.Headers["Cookie"] = sharedCookie;
        OperationContext.Current.OutgoingMessageProperties[
            HttpRequestMessageProperty.Name] = request;

        otherClient.DoSomethingElse();
    }
}

使用 WCF 和 WCF 创建的此服务引用独立于实际的通信媒介，这意味着这些服务可以使用 web 服务或远程处理或 MSMQ 来使用。而且remoting和MSMQ没有Cookies的概念。

使用 WSDL.exe 更好地创建您的 Web 服务引用并将生成的类添加到您的项目中。我做了同样的事情。
