Question

在下面的类中，如何将DBContext添加为泛型类型参数：

public abstract class Repository<T> : IRepository<T> where T : class
{
    private MyDBContext dataContext;
    private readonly IDbSet<T> dbset;

    protected Repository(IDatabaseFactory databaseFactory)
    {
        DatabaseFactory = databaseFactory;
        dbset = DataContext.Set<T>();
    }

    protected IDatabaseFactory DatabaseFactory
    {
        get;
        private set;
    }

    protected MyDBContext DataContext
    {
        get { return dataContext ?? (dataContext = DatabaseFactory.Get()); }
    }

    public virtual void Add(T entity)
    {
        dbset.Add(entity);
    }

    public virtual void Update(T entity)
    {
        dbset.Attach(entity);
        dataContext.Entry(entity).State = EntityState.Modified;
    }

    public virtual void Delete(T entity)
    {
        dbset.Remove(entity);
    }
}

以下内容：

public abstract class Repository<C, T> : IRepository<T> where T

它会起作用吗？如何实施？

你的意思是这样吗？

public abstract class Repository<TContext, TEntity> : IRepository<TContext, TSet>
    where TContext : DbContext
    where TEntity : class
{
    private TContext context;
    private readonly IDbSet<TEntity>;

    // ...
}

基本上只需用MyDBContext替换TContext的所有引用。
