Epicor 10.1.5 SessionModSvcContractClient注销

Question

是否有人遇到过SessionModSvcContractClient注销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，它们工作得很好。有人能帮我弄清楚为什么会这样吗?或者3之间的区别。

我基本上是在尝试使用WCF指南中的create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;

        //Epicor credentials:
        string epicorUserID = "XXX";
        string epiorUserPassword = "XXX";


        string scheme = "http";
        if (bindingType == EndpointBindingType.BasicHttp)
        {
            scheme = "https";
        }

        UriBuilder builder = new UriBuilder(scheme, "localhost");

        string webServicesLink = "XXX/";

        builder.Path = webServicesLink + "Ice/Lib/SessionMod.svc";
        SessionModSvcContractClient sessionModClient = GetClient < SessionModSvcContractClient, SessionModSvcContract > (builder.Uri.ToString(), epicorUserID, epiorUserPassword, bindingType);

        builder.Path = webServicesLink + "Erp/BO/AbcCode.svc";
        ABCCodeSvcContractClient abcCodeClient = GetClient<ABCCodeSvcContractClient, ABCCodeSvcContract>(builder.Uri.ToString(), epicorUserID, epiorUserPassword, bindingType);

        Guid sessionId = Guid.Empty;
        sessionId = sessionModClient.Login();

        //Create a new instance of the SessionModSvc. Do this because when you call any method on the service
        //client class, you cannot modify its Endpointbehaviors.
        builder.Path = webServicesLink + "Ice/Lib/SessionMod.svc";
        sessionModClient = GetClient < SessionModSvcContractClient, SessionModSvcContract > (builder.Uri.ToString(),epicorUserID,epiorUserPassword,bindingType);

        sessionModClient.Endpoint.EndpointBehaviors.Add(new HookServiceBehavior(sessionId, epicorUserID));
        abcCodeClient.Endpoint.EndpointBehaviors.Add(new HookServiceBehavior(sessionId, epicorUserID));

        var ts = new ABCCodeTableset();
        abcCodeClient.GetNewABCCode(ref ts);

        if (newRow != null)
        {
            newRow.ABCCode = "G";
            newRow.CountFreq = 30;
            newRow.StockValPcnt = 100;
            abcCodeClient.Update(ref ts);

                    field.SetValue(backupRow, fieldValue);
                }
                ts.ABCCode.Add(backupRow);
                ts.ABCCode[0].CountFreq = 45;

请参阅我的另一个答案，但作为另一种选择，您可能需要考虑这种访问服务的方法。

如果您可以访问客户端DLL，那么这段代码可能更容易：

    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
