public class IEntity
{
public int Id;
}
public interface IRepository<T> where T: IEntity
{
IEnumerable<T> List { get; }
void Add(T entity);
void Delete(T entity);
void Update(T entity);
T FindById(int Id);
}
[Table("Author")]
public partial class Author : IEntity
{
public int Id { get; set; }
[Required]
public string authorname { get; set; }
}
然后我们继续实现这些接口来创建我们的特定存储库
public class AuthorRepository : IRepository<Author>
{
Model1 _authorContext;
public AuthorRepository()
{
_authorContext = new Model1();
}
public IEnumerable<Author> List
{
get
{
return _authorContext.Authors;
}
}
public void Add(Author entity)
{
_authorContext.Authors.Add(entity);
_authorContext.SaveChanges();
}
public void Delete(Author entity)
{
_authorContext.Authors.Remove(entity);
_authorContext.SaveChanges();
}
public void Update(Author entity)
{
_authorContext.Entry(entity).State = System.Data.Entity.EntityState.Modified;
_authorContext.SaveChanges();
}
public Author FindById(int Id)
{
var result = (from r in _authorContext.Authors where r.Id == Id select r).FirstOrDefault();
return result;
}
}
