我有以下行动结果
public ActionResult TheMostClickedEmailReport(int ID, int gonderim,int? page)
{
int pageIndex = page ?? 1;
int pagesize = 10;
MailingClickService mailingclickservice = new MailingClickService();
TemplateLinkService tmpservice = new TemplateLinkService();
int FirmID = (int)Session["FirmID"];
var linkler = mailingclickservice.GetByCriteria(x => x.MailingID == ID && x.Gonderim == gonderim && x.Mailing.FirmUser.FirmID == FirmID).IslemSonucu.GroupBy(x => x.MailingEmail).ToPagedList(pageIndex, pagesize);
ViewBag.gonderim = gonderim;
ViewBag.MailingID = ID;
List<EmailLinkClickReport> emailcliklistreport = new List<EmailLinkClickReport>();
if (linkler.Count() > 0)
{
foreach (var item in linkler)
{
EmailLinkClickReport emaillinkclick = new EmailLinkClickReport();
emaillinkclick.Key = item.Key;
emaillinkclick.TotalClicksCount = item.Select(x => x.MailingEmail).Count();
emailcliklistreport.Add(emaillinkclick);
}
return View(emailcliklistreport);
}
else
{
return RedirectToAction("MailingReport", "Report", new { id = ID, gonderim = gonderim });
}
}
linkler 有50个数据。我使用 foreach(链接器中的项目)
从 linkler 中选择10个数据我想在v ar linkler = mailingclickservice.GetByCriteria(x => x.MailingID == ID && x.Gonderim == gonderim && x.Mailing.FirmUser.FirmID == FirmID).IslemSonucu.GroupBy(x => x.MailingEmail).ToPagedList(pageIndex, pagesize);
中选择10个数据
部分
但是我不知道如何通过返回视图将链接器转换为IPagedList?
如果我返回以下代码
return View(emailcliklistreport);
如下所示
return View(emailcliklistreport.ToPagedList(pageIndex,pagesize);
这对我来说不合逻辑,因为我两次返回列表
您有什么建议并建议我更改我的代码。
如何通过强制转换ToPagedList来返回链接器以进行查看?
答案 0 :(得分:1)
ToPagedList
应该是您在将数据集返回到视图之前对数据集执行的最后一个操作。就目前而言,您完全放弃了PagedList
,只是将List<EmailLinkClickReport>
返回到视图。
另外,对于什么是值得的,无论如何都不需要foreach循环,因为你可以使用LINQ的Select
方法来转换数据集。尝试:
var linkler = mailingclickservice
.GetByCriteria(x =>
x.MailingID == ID &&
x.Gonderim == gonderim &&
x.Mailing.FirmUser.FirmID == FirmID)
.IslemSonucu.GroupBy(x => x.MailingEmail)
.Select(x => new EmailLinkClickReport
{
Key = x.Key;
TotalClicksCount = x.Count();
})
.ToPagedList(pageIndex, pagesize);
我添加了宽松的间距,使其更容易阅读。唯一的新部分是Select
电话。同时从Select(x => x.MailingEmail)
移除了TotalClickCounts
爵士乐,因为它只会增加额外的处理时间。
