如何使用CRM Dynamics 2013/2015中的插件用相关实体更新CRM中的实体

Question

我是CRM新手，我正在努力使用插件来更新实体，我在创建消息时在PhoneCall Entity术前注册了一个插件，然后查询相关实体并将相关实体的数据写入我的PhoneCall实体，尽管我似乎收到一个错误，指出GUID xxxxx的记录不存在。

这是下面的代码；

  public void Execute(IServiceProvider serviceProvider)
    {
        ITracingService tracingService = (ITracingService)serviceProvider.GetService(typeof(ITracingService));
        IPluginExecutionContext context = (IPluginExecutionContext)serviceProvider.GetService(typeof(IPluginExecutionContext));

        if (context == null)
        {
            throw new ArgumentNullException("localContext");
        }

        IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));

        IOrganizationService service = serviceFactory.CreateOrganizationService(context.InitiatingUserId);

        if (context.InputParameters.Contains("Target") && context.InputParameters["Target"] is Entity)
        {
            Entity phoneCallEntity = (Entity)context.InputParameters["Target"];

            if (phoneCallEntity.LogicalName != "phonecall")
                return;


            if (context.MessageName == "Create")
            {
                try
                {
                    QueryExpression qe = new QueryExpression("new_zoiperhistorydata");
                    qe.ColumnSet = new ColumnSet("new_regardingobjectid", "new_callduration");

                    var ZoiperData = service.RetrieveMultiple(qe);

                    if (ZoiperData != null && ZoiperData.Entities.Count > 0)
                    {

                        foreach (Entity entity in ZoiperData.Entities)
                        {
                            if (entity.Attributes.Contains("new_callduration"))
                                phoneCallEntity.Attributes["new_callduration"] = entity.Attributes["new_callduration"].ToString();
                        }
                    }

                    service.Update(phoneCallEntity);
                }
                catch (System.Exception ex)
                {
                    Console.WriteLine("The application terminated with an error.");
                    Console.WriteLine(ex.Message);

                    // Display the details of the inner exception.
                    if (ex.InnerException != null)
                    {
                        Console.WriteLine(ex.InnerException.Message);

                        FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault> fe = ex.InnerException
                            as FaultException<Microsoft.Xrm.Sdk.OrganizationServiceFault>;
                        if (fe != null)
                        {
                            Console.WriteLine("Timestamp: {0}", fe.Detail.Timestamp);
                            Console.WriteLine("Code: {0}", fe.Detail.ErrorCode);
                            Console.WriteLine("Message: {0}", fe.Detail.Message);
                            Console.WriteLine("Trace: {0}", fe.Detail.TraceText);
                            Console.WriteLine("Inner Fault: {0}",
                                null == fe.Detail.InnerFault ? "No Inner Fault" : "Has Inner Fault");
                        }
                    }
                }


            }

代码在service.Update(phoneCallEntity)上失败；

您的帮助将不胜感激。

问题是您在Create事件的操作前阶段运行插件。 实际上，在此阶段未创建电话呼叫（并且没有ID），您会收到报告的错误消息。 实际上，您不必使用service.Update方法自己更新电话。 由于操作一直在进行，因此您只需更新目标服务器上所需的字段，然后让CRM来完成其余的工作即可：
