C# .Net MVC Razor 檢視靜態分頁導航欄生成器
這裡貼出3個重要組成部分
1.分頁導航欄主演算法程式碼（包括 @Html 擴充套件方法）
2.HTML 頁面呼叫程式碼(包括導航欄樣式)
3.Controller 控制器程式碼
引數說明：pc（pageCount），總頁數
其中的 2 是：pageIndex ，當前頁索引；使用的是預設路由也就是 {controller}/{action}/{id} 形式的路由定義
5.效果展示
注：實現效果簡單，如同學們有時間豐富一下配置引數，讓其可設定性更強些。
豐富完了帖回來我也用哈

2.HTML 頁面呼叫程式碼(包括導航欄樣式)
@{
Layout = null;
}
@using EB.Ctrl.Utility;
<!DOCTYPE html>
<html>
<head>
<title>Paination</title>
<style>
#pagination{float:right}
#pagination a {
text-decoration: none;
border: 1px solid #AAE;
color: #666;
}
#pagination a:hover {
BORDER-BOTTOM: #c00 1px solid; BORDER-LEFT: #c00 1px solid; BACKGROUND: #c00; COLOR: #fff; BORDER-TOP: #c00 1px solid; BORDER-RIGHT: #c00 1px solid; TEXT-DECORATION: none
}
#pagination a, #pagination span {
display: inline-block;
padding: 0.1em 0.4em;
margin-right: 5px;
margin-bottom: 5px;
}
#pagination .current {
background: #bc0057;
color: #fff;
border: 1px solid #c00;
}
#pagination .current.prev, #pagination .current.next{
color:#999;
border-color:#999;
background:#fff;
}
</style>
</head>
<body>
<!--使用這個擴充套件頁面必須引用 using EB.Ctrl.Utility 名稱空間-->
@Html.PaginationBar(new PaginationBarBilder("http://www.****.com/EBusiness/Paination/{0}?pc=" + this.ViewBag.PagePars.PageCount.ToString(), this.ViewBag.PagePars.PageCount, this.ViewBag.PagePars.PageIndex))
</body>
</html>

3.Controller 控制器程式碼
using System.Web.Mvc;
using EB.Ctrl.Utility;
using EB.Sys.Extension;
namespace EB.Ctrl.Controllers
{
public class EBusinessController : Controller
{
public ActionResult Paination(string id,string pc)
{
PageBarPars pars = new PageBarPars();
pars.PageCount = pc.GetInt();
pars.PageIndex = id.GetInt();
this.ViewBag.PagePars = pars;
return View();
}
}
}
