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
