如何使分頁從1而不是0開始

Question

我使用了Nerddinner教程的分頁示例。但我也想添加頁碼，服用點這樣的：

< < < 1 2 3 4 5 6 >>>

下面的代碼，如果我從0開始我的傳呼工作，但不從1.我該如何解決這個問題？

這裏是我的代碼：

PaginatedList.cs

public class PaginatedList<T> : List<T> { 

    public int PageIndex { get; private set; } 
    public int PageSize { get; private set; } 
    public int TotalCount { get; private set; } 
    public int TotalPages { get; private set; } 

    public PaginatedList(IQueryable<T> source, int pageIndex, int pageSize) { 
     PageIndex = pageIndex; 
     PageSize = pageSize; 
     TotalCount = source.Count(); 
     TotalPages = (int) Math.Ceiling(TotalCount/(double)PageSize); 

     this.AddRange(source.Skip(PageIndex * PageSize).Take(PageSize)); 
    } 

    public bool HasPreviousPage { 
     get { 
      return (PageIndex > 0); 
     } 
    } 

    public bool HasNextPage { 
     get { 
      return (PageIndex+1 < TotalPages); 
     } 
    } 
} 

UserController.cs

public ActionResult List(int? page) 
    { 
     const int pageSize = 20; 

     IUserRepository userRepository = new UserRepository(); 
     IQueryable<User> listUsers = userRepository.GetAll(); 
     PaginatedList<User> paginatedUsers = new PaginatedList<User>(listUsers, page ?? 0, pageSize); 

     return View(paginatedUsers); 
    } 

List.cshtml

個

@if (Model.HasPreviousPage) 
{ 
    @Html.RouteLink(" Previous ", "PaginatedUsers", new { page = (Model.PageIndex - 1) }) 
} 

@for (int i = 1; i <= Model.TotalPages; i++) 
{ 
    @Html.RouteLink(@i.ToString(), "PaginatedUsers", new { page = (@i) }) 
} 

@if (Model.HasNextPage) 
{ 
    @Html.RouteLink(" Next ", "PaginatedUsers", new { page = (Model.PageIndex + 1) }) 
} 

Answer 1

PaginatedList.cs

.Skip((PageIndex -1) * PageSize).Take(PageSize) 

UserController.cs

public ActionResult List(int page = 1) 
{ 

Answer 2

我有此變化：

PaginatedList.cs

public PaginatedList(IQueryable<T> source, int pageIndex, int pageSize) { 
     . 
     . 
     . 
     this.AddRange(source.Skip((PageIndex -1) * PageSize).Take(PageSize)); 
    } 

public bool HasPreviousPage { 
     get { 
      return (PageIndex > 1); 
     } 
    } 

    public bool HasNextPage { 
     get { 
      return (PageIndex < TotalPages); 
     } 
    } 

個

UserController.cs

public ActionResult List(int? page) 
    { 
     const int pageSize = 20; 

     page = (page < 1) ? 1 : page ?? 0; 
     . 
     . 
     . 

Answer 3

我會建議使用庫而不是去編寫自己的代碼分頁。 MvcPaging是其中的一個庫。
