Asp.net MVC 简单分页 自做简单分页
Asp.net MVC 简单分页:
public static string Pager(int page,int pageSize,int total)
{
var htmlStr = "<div class=\"pagination\">";
var pageCount = Math.Ceiling((double)total / pageSize);

else
{
url += "&page={0}";
}
}
else
{
url = Regex.Replace(url,@"page=\d*", "page={0}");
}
if (url.IndexOf("pageSize") < 0)
{
if (url.IndexOf('?') < 0)
{
url += "?pageSize={1}";
}
else
{
url += "&pageSize={1}";
}
}
else
{
url = Regex.Replace(url, @"pageSize=\d*", "pageSize={1}");
}
var perEveryTime = 5;//每次显示可点击页数

调用:
后台:var t = HtmlHelper2.Pager(page, pageSize, users.Count);
ViewBag.t = t;
前台:
@Html.Raw(ViewBat.t)
