为嘛调不到这个方法？大侠们帮帮忙……
public class MockAnnounceService : IAnnounceService
  {
  public List<AnnounceInfo> GetAnnounceByCategory(CategoryInfo category)
  {
  List<AnnounceInfo> announces = new List<AnnounceInfo>();

  for (int i = 1; i <= 10; i++)
  {
  AnnounceInfo announce = new AnnounceInfo
  {
  ID = i,
  Title = category.Name + "的第" + i + "则公告",
  Content = "全体同学早上七点起床做俯卧撑！"
  };
  announces.Add(announce);
  }
  return announces;
  }
这是实现接口的类，


这是接口的定义：
  public class ICategoryService
  {
  /// <returns></returns>
  CategoryInfo GetDetail(int id);
  /// <summary>
  /// 取得所有分类
  /// </summary>
  /// <returns></returns>
  List<CategoryInfo> GetAll();
  }
}



这是组件生成类：
  public sealed class ServiceBuilder
  {
  /// <summary>
  /// 创建分类服务组件
  /// </summary>
  /// <returns>分类服务组件</returns>
  public static ICategoryService BulidCategoryService()
  {
  return new MockCategoryService();
  }

  /// <summary>
  /// 创建公告服务组件
  /// </summary>
  /// <returns>公告服务组件</returns>
  public static IAnnounceService BuildAnnounceService()
  {
  return new MockAnnounceService();
  }
  }


这是调用的地方：
  public ActionResult Index()
  {
  ICategoryService cServ = ServiceBuilder.BulidCategoryService();
  ViewData["Categories"] = cServ.GetAll();
  return View("Index");
  }

红色为出错处："MvcWeb.Models.Interfaces.ICategoryService.GetAll()"不可访问，因为它受保护级别限制

------解决方案--------------------
public class MockAnnounceService : IAnnounceService
public static ICategoryService BulidCategoryService()
{
return new MockCategoryService();
}

 public class ICategoryService {
/// <returns></returns>
CategoryInfo GetDetail(int id);
/// <summary>
/// 取得所有分类
/// </summary>
/// <returns></returns>
List<CategoryInfo> GetAll();
}
}

------解决方案--------------------
起码把MockCategoryService这个类发出来看看把。

static下

看你的类名，好像不是继承ICategoryService的。你应该有一个MockCategoryService类。发上来瞧瞧。
