我有一個擴展方法可以完成分頁。有23項在目錄中,以便3頁,使用for循環獲取首頁問題的分頁
我的控制器簡稱:
public ActionResult Index(int? page)
{
List<ScormModuleInfo> modules = new List<ScormModuleInfo>();
string[] dirs = Directory.GetDirectories(scormRootDir);
int totalResults = dirs.Count();
int pageSize = PageSizeSettings.ScormPackages;
int totalPages = Math.Max(Convert.ToInt32(Math.Ceiling((double)totalResults/pageSize)), 1);
if (page >= 1)
{
int startresult = ((Math.Max(1, **page**) - 1) * pageSize) + 1;
int endresult = Math.Min(startresult + (pageSize - 1), totalResults);
for (int i = startresult; i <= endresult; i++)
{
//more code
}
}
視圖
:
<div class="actions-left">
<%= Html.GlobalisedPageLinks(Amico.Web.Mvc.Extensions.Enums.PageLinksFormat.Empty, Model.CurrentPage, Model.PageSize, Model.Total, x => Url.Action("Index", "Scorm", new { area = "Admin", page = x }))%>
</div>
擴展方法:
public static string GlobalisedPageLinks(this HtmlHelper html, Amico.Web.Mvc.Extensions.Enums.PageLinksFormat format, int currentPage, int pageSize, int totalResults, Func<int, string> pageUrl)
{
int totalPages = Math.Max(Convert.ToInt32(Math.Ceiling((double)totalResults/pageSize)), 1);
int startresult = ((Math.Max(1, currentPage) - 1) * pageSize) + 1;
int endresult = Math.Min(startresult + (pageSize - 1), totalResults);
string pagesText = html.Resource(Resources.Global.PageLinks.PageLinksFormatPages, currentPage, totalPages);
string resultsText = html.Resource(Resources.Global.PageLinks.PageLinksFormatResults, startresult, endresult, totalResults);
string firstText = html.Resource(Resources.Global.PageLinks.First);
string previousText = html.Resource(Resources.Global.PageLinks.Previous);
string nextText = html.Resource(Resources.Global.PageLinks.Next);
string lastText = html.Resource(Resources.Global.PageLinks.Last);
return "<span class='page-links'>" + html.PageLinks(format, currentPage, pageSize, totalResults, pageUrl,
pagesText, resultsText, firstText, previousText, nextText, lastText) + "</span>";
}
我在Math.Max(1,page)上爲startresult獲取一條紅線,指出:最佳重載方法是(十進制,十進制)我有一些inval ID參數?
啊,非常感謝你會記住這個! – 2013-03-11 09:44:43
