使用Linq查询如何将数据插入两个不同的表

Question

这里我使用EntityFramework将数据插入两个不同的表中。请建议我怎么办

ClassFile的

namespace ImageWithallCtrls.Models
{
    public partial class TwoTabes
    {
        public partial  class Employee
        {
            public int id { get; set; }
            public string Name { get; set; }
            public string EMail { get; set; }
            public string Password { get; set; }
            public virtual ICollection<Department> Department { get; set; }
        }

        public  class Department
        {
            public int DID { get; set; }
            public string D_Name { get; set; }
            public string Employee_Name { get; set; }
            public Nullable<decimal> Salary { get; set; }
        }

    }
}

HomeController.cs

public ActionResult InserTwise(TwoTabes model )
{
     Employee emp = db.Employees.Create();
     emp.Name = model.Employee.Name;         
}

我在这里遇到错误"model.Employee.Name"
