[C#]Asp.net MVC:自定义的MVC Pager

实例懒得做。切几个图把代码发上要用的自己搞啦~

下面是一个helper类。

Code
namespace System.Web.Mvc
{
    public enum BarStyle
    {
        yahoo, digg, meneame, flickr, sabrosus, scott, quotes, black, black2, grayr, yellow, jogger, starcraft2, tres, megas512, technorati, youtube, msdn, badoo, viciao, yahoo2, green_black
    }
    public static class PagerBarExtension
    {

        public static string RenderPagerBar(this HtmlHelper html, int page, int total)
        {
            return RenderPagerBar(html, page, total, BarStyle.technorati);
        }

        public static string RenderPagerBar(this HtmlHelper html, int page, int total, BarStyle style)
        {
            return RenderPagerBar(html, page, total, style, total);
        }

        public static string RenderPagerBar(this HtmlHelper html, int page, int total, BarStyle style, int show)
        {
            if (total == 1)
            {
                return "";
            }
            else
            {
                StringBuilder sb = new StringBuilder();
                string _path = html.ViewContext.HttpContext.Request.Path;
                sb.Append("<div class=\"");
                sb.Append(style.ToString());
                sb.Append("\" >");

                string queryString = html.ViewContext.HttpContext.Request.QueryString.ToString();
                if (queryString.IndexOf("page=") < 0)
                {
                    queryString += "&page=" + page;
                }
                Regex re = new Regex(@"page=\d+", RegexOptions.IgnoreCase);
                string result = re.Replace(queryString, "page={0}");

                if (page != 1)
                {
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"第一页\">{1}</a></span>", _path + "?" + string.Format(result, 1), "<<");
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"上一页\">{1}</a></span>", _path + "?" + string.Format(result, page – 1), "<");
                }
                if(page>(show+1))
                {
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"前" + (show + 1) + "页\">{1}</a></span>", _path + "?" + string.Format(result,page–(show + 1)), "..");

                }
                for (int i = page–show; i <= page+show; i++)
                {
                    if (i == page)
                    {
                        sb.AppendFormat("<span class=\"current\">{0}</span>", i);
                    }
                    else
                    {
                        if (i > 0 & i<=total)
                        {
                            sb.AppendFormat("<span><a href=\"{0}\">{1}</a></span>", _path + "?" + string.Format(result, i), i);
                        }
                    }
                }
                if (page < (total–(show)))
                {
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"后" + (show + 1) + "页\">{1}</a></span>", _path + "?" + string.Format(result, page + (show + 1)), "..");

                }
                if (page < total)
                {
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"下一页\">{1}</a></span>", _path + "?" + string.Format(result, page + 1), ">");
                    sb.AppendFormat("<span><a href=\"{0}\" title=\"最后一页\">{1}</a></span>", _path + "?" + string.Format(result, total), ">>");

                }
                sb.AppendFormat("<span class=\"current\">共{1}页</span>", page, total);
                sb.Append("</div>");
                return sb.ToString();
            }
        }
    }
}

使用（VIEW）：

Code
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

<asp:Content ID="indexHead" ContentPlaceHolderID="head" runat="server">
    <title>Home Page</title>
    <link href="/Content/pagecss.css" rel="stylesheet" type="text/css" />
</asp:Content>
    
<asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server">
    <%= Html.ActionLink("带其它参数","Index",new {s = "MVC"} )%>
    <%= Html.ActionLink("带其它参数2","Index",new { cid = 3} )%>
    <%= Html.ActionLink("带其它参数3","Index",new {s = "MVC" , cid = 5} )%>
    
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]))%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.badoo )%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.badoo,3 )%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.black,4 )%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.digg,5 )%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.flickr,3 )%>
    <%= Html.RenderPagerBar(Convert.ToInt32(ViewData["Page"]),Convert.ToInt32(ViewData["Total"]),BarStyle.grayr,3 )%>
    
</asp:Content>

最后一个int参数表示显示当前页左右各多少个页码

 效果：

controller:

Code
        public ActionResult Index(int? page,string s,int? cid)
        {
            int _page = page??1;
            ViewData["Message"] = "Welcome to ASP.NET MVC!";
            ViewData["Page"] = _page;
            ViewData["Total"] = 20;

            return View();
        }

不是啥高深的东西，不过蛮实用，

计算总页数和skip啥的就自己搞啦。给宝宝换尿布了
