我如何使用限制和偏移量与pagedlist在Asp.Net MVC中进行分页？

Question

我正在使用PagedList进行分页，但是它需要将所有记录放在列表中然后进行分页，这将浪费很长时间来呈现页面，因此，我想使用LIMIT和OFFSET使用PagedLit进行真正的分页并浪费很短的时间。

我如何使用带有LIMIT和OFFSET的PagedList来创建真正的分页？

模型

public class SearchUsuarioModel{

    public IPagedList<UpUsuarioAdminModel> listaModel               { get; set; } //list model
    public IPagedList<Usuario> listaObject                          { get; set; } //list all objects

    //Status
    public IEnumerable<SelectListItem> status                       { get; set; }    
    public int statusSelected                                       { get; set; }

    public String nome                                              { get; set; }
    public String role                                              { get; set; }
    public int limit                                                { get; set; }
    public int offset                                               { get; set; }

    public int pageSize                                             { get; set; }
    public int pageNumber                                           { get; set; }

    public SearchUsuarioModel(){
        listaModel = new List<UpUsuarioAdminModel>().ToPagedList(1, 50);

}

控制器

        model.offset = offSet ?? 0;
        model.pageNumber = page ?? 1;
        model.pageSize = model.limit;

        //listas
        IList<Usuario> _listaObject = new List<Usuario>();
        IList<UpUsuarioAdminModel> _listaModel = new List<UpUsuarioAdminModel>();

        UsuarioDAO dao = new UsuarioDAO();
        try{            

           _listaObject = dao.findAllOffset(model.limit, model.offset);

        } catch (Exception e){
            Debug.WriteLine("viewAllAdmin UsuarioController: " + e.Message);
        }

        if (_listaObject.Count > 0){
            foreach (Usuario u in _listaObject){
                UpUsuarioAdminModel m = new UpUsuarioAdminModel();
                m.id = u.id;
                m.nome = u.nome;
                m.email = u.email;
                m.roleSelected = u.role.ToString();
                m.statusDesc = u.status == 1 ? "Ativo" : "Inativo";

                m.contrato = u.imgContrato;
                if (u.contato != null){
                    //Debug.WriteLine("Telefone: " + string.IsNullOrEmpty(u.contato.telefone1));
                    m.telefone1 = string.IsNullOrEmpty(u.contato.telefone1) ? "" : u.contato.telefone1;
                }
                _listaModel.Add(m);
            }
        }

        model.listaModel = _listaModel.ToPagedList(model.pageNumber, model.limit);
        model.listaObject = dao.findAll().ToPagedList(model.pageNumber, model.limit);
        return View(model);
    }
