Epicor 10.1.5 SessionModSvcContractClient注销

Question

有没有人遇到过 SessionModSvcContractClient Logout 函数抛出异常的问题：附加信息：

Object reference not set to an instance of an object.

当我尝试 LogoutAsync 和 Close 方法时，它们运行良好。谁能帮我弄清楚为什么会这样或 3.

之间的区别

我基本上是在尝试使用 WCF 指南中的创建测试

    static void Main(string[] args)
    {

        //use a self-signed certificate in IIS, be sure to include the following code. This code speeds up calls to the services and prevents the method from trying to validate the certificate with the known authorities.
        ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, errors) => { return true; };

        //You can toggle the value assigned to this variable to test the two bindings: SOAPHttp or BasicHttp
        EndpointBindingType bindingType = EndpointBindingType.SOAPHttp;

请参阅我的其他答案，但作为替代方案，您可能需要考虑使用这种访问服务的方法。

如果您可以访问客户端 DLL，那么这段代码可能会更简单：

    static void Main(string[] args)
    {
        // Hard-coded LogOn method 
        // Reference: Ice.Core.Session.dll
        Ice.Core.Session session = new Ice.Core.Session("manager", "manager", "net.tcp://AppServer/MyCustomerAppserver-99999-10.0.700.2");

        // References: Epicor.ServiceModel.dll, Erp.Contracts.BO.ABCCode.dll
        var abcCodeBO = Ice.Lib.Framework.WCFServiceSupport.CreateImpl<Erp.Proxy.BO.ABCCodeImpl>(session, Erp.Proxy.BO.ABCCodeImpl.UriPath);

        // Call the BO methods
        var ds = abcCodeBO.GetByID("A");
        var row = ds.ABCCode[0];

        System.Console.WriteLine("CountFreq is {0}", row.CountFreq);
        System.Console.ReadKey();
    }

只需添加对以下内容的引用：

Ice.Core.Session.dll
Epicor.ServiceModel.dll
Erp.Contracts.BO.ABCCode.dll

Answer 2

在我更改配置以适应我的环境后，你的代码对我来说工作正常。

您似乎遵循了 Epicor10_techrefWCFServices_101400.pdf 指南第 15 页的第 7 步，并在 Login() 之后正确地创建了 SessionModSvc 的新实例。但是，如果您从第 18 页复制了 Main 方法的完整代码，那么它就丢失了，我可以复制您的问题。

检查您正在编译的代码是否在调用 .Login() 后创建了 SessionModSvc 的新实例。
