问题描述

DbMigrationsConfiguration(TContext).Seed 方法的问题

模型

 namespace MvcDemo.Models
{
    public class SysController:MvcDemoEntities
    {
        public string ControllerDisplayName { get; set; }
        public string Ico { get; set; }
    }
}

上下文

 namespace MvcDemo.Models
{
    public class MvcDemoEntities:DbContext
    {
        public DbSet<SysController> syscontroller { get; set; }
    }
}

这个是seed方法

 namespace MvcDemo.Models
{
    public class Configuration:DbMigrationsConfiguration<MvcDemoEntities>
    {
        protected override void Seed(MvcDemoEntities context)
        {
            var sysControllers = new List<SysController>
        {
            new SysController
            {
                ControllerDisplayName="abcd",
            },
            new SysController
            {
                ControllerDisplayName="asdaf",
            },
            new SysController
            {
                ControllerDisplayName="dfsgs",
            },
            new SysController
            {
                ControllerDisplayName="dgsds",
            },
            new SysController
            {
                ControllerDisplayName="fgsdfsd",
            },
            new SysController
            {
                ControllerDisplayName="sdgdf",
            },

        };
        }

    }
}

然后在Global.asax中声明

 protected void Application_Start()
        {
            System.Data.Entity.Database.SetInitializer(new MvcDemo.Models.Configuration());
            AreaRegistration.RegisterAllAreas();

            WebApiConfig.Register(GlobalConfiguration.Configuration);
            FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
            RouteConfig.RegisterRoutes(RouteTable.Routes);
            BundleConfig.RegisterBundles(BundleTable.Bundles);
        }

结果就这样了

这是什么原因？怎么解决？

解决方案

在你的方法名后用尖括号加上你用的TContext的参数就可以了。

解决方案二：

HibernateDao的countCriteriaResult方法有问题的
