Question

我一直在用 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。我创建了一个包含以下代码的类。

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堂课时，我得到一个错误说：

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

错误在5线向下（围绕左右）

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);
        }
    }
}

Answer 1

您InsertShows没有InsertShow。您的界面需要InsertShow。
