C# .Net MVC Razor 视图静态分页导航栏生成器

这里贴出3个重要组成部分

1.分页导航栏主算法代码（包括 @Html 扩展方法）

2.HTML 页面调用代码(包括导航栏样式)

3.Controller 控制器代码

4.测试路径：http://www.iqingcao.com/EBusiness/Paination/2?pc=10（这里只是个本机测试url实例，不同机子测试 域名部分（www.iqingcao.com）需要替换一下）

参数说明：pc（pageCount），总页数

其中的 2 是：pageIndex ，当前页索引；使用的是默认路由也就是 {controller}/{action}/{id} 形式的路由定义

5.效果展示

注：实现效果简单，如同学们有时间丰富一下配置参数，让其可设置性更强些。

丰富完了帖回来我也用哈

1.分页导航栏主算法代码

}

2.HTML 页面调用代码(包括导航栏样式)

@{
Layout = null;
}
@using EB.Ctrl.Utility;

@Html.PaginationBar(new PaginationBarBilder("http://www.iqingcao.com/EBusiness/Paination/{0}?pc=" + this.ViewBag.PagePars.PageCount.ToString(), this.ViewBag.PagePars.PageCount, this.ViewBag.PagePars.PageIndex))

------------------------------------------------------------------------------------------------------------------------------

3.Controller 控制器代码

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();
}
}
}
