ASP.NET员工管理系统简易分了层主要只是就一个传值和CRUD

 

实体类

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace EmpPrj.Entity
{
   public  class y_EmployeeEntity
    {
        public int EmployeeId { get; set; }

        public string EName { get; set; }

        public string Mobile { get; set; }

        public string HAddress { get; set; }

        public string Kdate { get; set; }

    }
}

using System;

        public string RelationShip { get; set; }
