我正在尝试更新帐户实体的所有关联联系人的电话号码。以下是我使用的代码，

public class Plugin:IPlugin
{
    public void Execute(IServiceProvider serviceProvider)
    {
        IPluginExecutionContext context = (IPluginExecutionContext)
        serviceProvider.GetService(typeof(IPluginExecutionContext));

        Entity entity;


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

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

            if (entity.LogicalName != "account") { return; }
        }
        else
        {
            return;
        }

        try
        {
            string telephoneNum = string.Empty;
            IOrganizationServiceFactory serviceFactory =(IOrganizationServiceFactory)serviceProvider.GetService(typeof(IOrganizationServiceFactory));
            IOrganizationService service =serviceFactory.CreateOrganizationService(context.UserId);

            var id = (Guid)context.OutputParameters["id"];
            telephoneNum = entity.GetAttributeValue<string>("telephone1");
            UpdateContact(service, id,telephoneNum);
        }
        catch (FaultException<OrganizationServiceFault> ex)
        {
            throw new InvalidPluginExecutionException(
            "An error occurred in the plug-in.", ex);
        }
    }

    private static void UpdateContact(IOrganizationService service, Guid id,string telephoneNUm)
    {
        using (var crm = new XrmServiceContext(service))
        {

            var res = from c in crm.CreateQuery("contact")
                      where c["parentcustomerid"].Equals(id)
                      select c;

            foreach (var c in res)
            {
                Entity e = (Entity)c;
                e["telephone1"] = telephoneNUm;
                crm.UpdateObject(e);
            }


            crm.SaveChanges();
        }
    }
}

我在更新时注册了插件，并且主要实体“帐户”但是每当我在电话字段中更改号码后尝试保存帐户表格时，我都会看到一个错误弹出。我错过了什么吗？谢谢你们！

只是一种预感..但我认为您以错误的方式获取 Id..尝试通过以下方式获取它：

Guid Id = context.PrimaryEntityId

但正如佩德罗建议的那样..您需要查看确切的错误是什么或尝试使用附加到进程来调试插件..
