c# - MS CRM 插件的一般错误

Question

我正在尝试运行 MS CRM 的示例插件。但我收到以下错误:

An error occurred. Contact a system administrator or refer to the Microsoft Dynamics CRM SDK troubleshooting guide.

这是代码:

public void Execute(IServiceProvider serviceProvider)
    {

        // Obtain the execution context from the service provider.
        IPluginExecutionContext context = (IPluginExecutionContext)
        serviceProvider.GetService(typeof(IPluginExecutionContext));


        // The InputParameters collection contains all the data passed in the message request.
        if (context.InputParameters.Contains("account") &&
        context.InputParameters["account"] is Entity)
        {
            // Obtain the target entity from the input parmameters.
            Entity entity = (Entity)context.InputParameters["account"];



            try
            {
                //check if the account number exist

                if (entity.Attributes.Contains("account number") == false)
                {

                    //create a task
                    Entity task = new Entity("task");
                    task["subject"] = "Account number is missing";
                    task["regardingobjectid"] = new EntityReference("account", new Guid(context.OutputParameters["id"].ToString()));

                    //adding attribute using the add function
                    // task["description"] = "Account number is missng for the following account. Please enter the account number";
                    task.Attributes.Add("description", "Account number is missng for the following account. Please enter the account number");



                    // Obtain the organization service reference.
                    IOrganizationServiceFactory serviceFactory = (IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
                    IOrganizationService service = serviceFactory.CreateOrganizationService(context.UserId);


                    // Create the task in Microsoft Dynamics CRM.
                    service.Create(task);


                }
            }

            catch (FaultException ex)
            {
                throw new InvalidPluginExecutionException("An error occurred in the plug-in.", ex);
            }

        }

    }
}//end class

这是一个示例代码，我已经验证了该插件使用的所有实体和字段都已定义并且位于该位置。但我不断收到此业务错误。

Answer 1

我找到了解决方案:我们不必明确提及“帐户”，而是必须使用:

Entity entity = (Entity)context.InputParameters["Target"];

第二个错误原因是 CRM 内部的限制，不允许创建新帐户。用于创建新的“联系人”时效果很好。

非常感谢大家的帮助。
