在存储库中有一个方法,如：

public virtual PaginatedList<T> Paginate<TKey>(int pageIndex,int pageSize,Expression<Func<T,TKey>> keySelector,bool>> predicate,params Expression<Func<T,object>>[] includeProperties)
{
    IQueryable<T> query = AllIncluding(includeProperties).OrderBy(keySelector);

    query = (predicate == null)
        ? query
        : query.Where(predicate);

    return query.ToPaginatedList(pageIndex,pageSize);
}

但是,当我尝试使用它时,像这样：

var a = repository.Paginate<Region>(pageNo,pageSize,x => x.ID,null);

我收到此错误：

Cannot implicitly convert type ‘int’ to
‘Domain.Entities.Dictionaries.Region’

我究竟做错了什么？
