Question

我尝试通过以下链接在Select（）中实现ThenInclude： https://github.com/beyourmarket/beyourmarket/blob/master/src/Frameworks/Repository.Pattern.Ef6/Repository.cs

之前：

 internal IQueryable<TEntity> Select(
            Expression<Func<TEntity, bool>> filter = null,
            Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null,
            List<Expression<Func<TEntity, object>>> includes = null,
            int? page = null,
            int? pageSize = null)
        {
            IQueryable<TEntity> query = this._dbSet;

            if (includes != null)
            {
                query = includes.Aggregate(query, (current, include) => current.Include(include));
            }

之后：

  internal IQueryable<TEntity> Select(
            Expression<Func<TEntity, bool>> filter = null,
            Func<IQueryable<TEntity>, IOrderedQueryable<TEntity>> orderBy = null,
            List<Expression<Func<TEntity, object>>> includes = null,
            Expression<Func<**???**>> thenInclude = null,

            int? page = null,
            int? pageSize = null)
        {
            IQueryable<TEntity> query = this._dbSet;

            if (includes != null)
            {
                if (thenInclude != null)
                {
                    query = includes.Aggregate(query, (current, include) => current.Include(include).ThenInclude(thenInclude));
                }
                else
                {
                    query = includes.Aggregate(query, (current, include) => current.Include(include));
                }
            }

请帮助我看看并给我一些建议。那样的方式可能与否。如果是，那么上面的thenInclude（Expression ??? >> thenInclude = null，）的类型是什么，

内部IQueryable <tentity> Select（Expression <func <tentity，bool =“” >> filter = null
