创建存储库

我一直在使用http://www.asp.net/mvc/tutorials/getting-started-with-ef-using-mvc/implementing-the-repository-and-unit-of-work-patterns-in-an-asp-net-mvc-application作为帮助我创建存储库的指导。我用下面的代码创建了一个类。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using TheatreGroup.Models;
namespace TheatreGroup.DAL
{
    public interface IShowRepository : IDisposable
    {
        IEnumerable<Show> GetShows();
        Show GetShowByID(int showId);
        void InsertShow(Show name);
        void DeleteShow(int showID);
        void UpdateShow(Show name);
        void Save();
    }
}

但是当我来创建第二个类时，我收到一个错误，说：

TheatreGroup.DAL.ShowRepository'

不实现接口成员 'TheatreGroup.DAL.IShowRepository.InsertShow（TheatreGroup.Models.Show）'。

错误在 5 行向下（四处走动）

using System.Data;
using TheatreGroup.Models;
namespace TheatreGroup.DAL
{
    public class ShowRepository: IShowRepository, IDisposable
    {
        private TheatreContext context;
        public ShowRepository(TheatreContext context)
        {
            this.context = context;
        }
        public IEnumerable<Show> GetShows()
        {
            return context.Shows.ToList();
        }
        public Show GetShowByID(int id)
        {
            return context.Shows.Find(id);
        }
        public void InsertShows(Show name)
        {
            context.Shows.Add(name);
        }
        public void DeleteShow(int showID)
        {
            Show shows = context.Shows.Find(showID);
            context.Shows.Remove(shows);
        }
        public void UpdateShow(Show name)
        {
            context.Entry(name).State = EntityState.Modified;
        }
        public void Save()
        {
            context.SaveChanges();
        }
        private bool disposed = false;
        protected virtual void Dispose(bool disposing)
        {
            if (!this.disposed)
            {
                if (disposing)
                {
                    context.Dispose();
                }
            }
            this.disposed = true;
        }
        public void Dispose()
        {
            Dispose(true);
            GC.SuppressFinalize(this);
        }
    }
}
