Question

这是我删除的问题的一部分，因为它太宽泛了我为我的博客存档创建了一个ActionLink，但我遇到了麻烦，因为我在其中调用了多个项目。

这是我的代码返回错误消息方法没有重载ActionLink需要7个参数

@model IEnumerable <Project.Models.ArchiveListModel>

@foreach (var item in Model)
{
<br />
@Html.ActionLink(item.AchiveMonth, item.AchiveYear, item.PostCount, "ArchiveBrowse", "Post", 
new { AchiveYear =  item.AchiveMonth, ArchiveMonth = item.AchiveYear, PostCount = item.PostCount }, null) 

}

这是我的原始代码，但没有链接，只提供清单

@foreach (var item in Model)
{
<br />
<li> @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(item.AchiveMonth) @item.AchiveYear (@item.PostCount) </li>   
} 
</fieldset><br/>

输出：

January 2013 (1)
February 2013 (1)
December 2012 (4)

这是我在控制器中的操作方式，但我知道它不起作用。 T_T

 public ActionResult Archive()
        {
            var archivelst = repository.AchiveList().ToList();
            return View(archivelst);
        }

  //this one below is not working
  public ActionResult ArchiveBrowse(string archive)
    {
        var achivemodel = db.Posts.Include("Posts").Single(a => a.Title == archive);
        return View(achivemodel);
    }
            return View(achivemodel);

我的ArchiveRepository

 public IQueryable<ArchiveListModel> AchiveList()
        {

            var ac = from Post in db.Posts
                     group Post by new { Post.DateTime.Year, Post.DateTime.Month }
                     into dategroup
                     select new ArchiveListModel()
                      {

                         AchiveYear = dategroup.Key.Year,
                         AchiveMonth = dategroup.Key.Month,
                         PostCount = dategroup.Count()

                       };

            return ac;
        }

在视图中调用多个项目的正确方法是什么？

我在这里尝试的是查看特定月份和年份下的帖子列表或博客档案。

最后，我能够使它工作，这是一个工作的一个

更新了ArchiveRepository

 public IQueryable<ArchiveListModel> AchiveList()
        {

            var ac = from Post in db.Posts
                     group Post by new { Post.DateTime.Year, Post.DateTime.Month }
                     into dategroup
                     select new ArchiveListModel()
                      {

                         AchiveYear = dategroup.Key.Year,
                         AchiveMonth = dategroup.Key.Month,
                         PostCount = dategroup.Count()

                       };

            return ac;
        }

更新了控制器

public ActionResult ArchiveBrowse(int AchiveYear, int AchiveMonth, int PostCount)
        {
            var archivemodel = (from a in db.Posts
                                where a.DateTime.Year == AchiveYear &&
                                      a.DateTime.Month == AchiveMonth
                                select a).ToList();


            return View(archivemodel);
        }

更新了视图

@foreach (var item in Model)
{
@Html.ActionLink(System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(item.AchiveMonth) + "" + item.AchiveYear + " (" + item.PostCount + ")",
  "ArchiveBrowse", "Post", new
  {
      AchiveYear = item.AchiveYear,
      AchiveMonth = item.AchiveMonth,
      PostCount = item.PostCount
  }, null) 

}

Answer 1

当你说“拨打多个项目”时，我仍然不清楚，所以这是我的答案，假设您想将months years (postcount)列表放入链接中。要获得此输出

January 2013 (1)
February 2013 (1)
December 2012 (4)

您可以连接字符串item.AchiveMonth，item.AchiveYear和item.PostCount：

@Html.ActionLink(item.AchiveMonth + " " + item.AchiveYear + " ("+ item.PostCount + ")",
"ArchiveBrowse", 
"Post", 
    new { 
          AchiveYear =  item.AchiveYear, 
          ArchiveMonth = item.AchiveMonth, 
          PostCount = item.PostCount },
 null)

然后在ArchiveBrowse中，确保您的参数正确排列：

public ActionResult ArchiveBrowse(string AchiveYear, string ArchiveMonth, string PostCount)
{
     //Not sure if you want to display posts in the clicked month/year
}

在ActionLink中使用多个项目的正确方法？
