    razor syntax question on converting a collection of 1 item

    Hey :)

    Im doin' my first razor only site, so i want to get everything top notch :)

    I have a collection of newsItems, from this collection I need to latest one on the stack and display it abit more in detail. So what I did so far is 

    @{
      @*First we need the list of news*@
       var listOfNews = @Model.news.OrderBy("newsPubDate desc");
      
      @*Get latest news to be used for top news*@
       var latestNews = @listOfNews.Take(1);
      }

    So at the moment "latestNews" is a collection of 1 newsItem.

    How do i cast/convert it into just a newsItem, so i can get the data out ?

    I know i can just do a foreach on the one item and it would work but find it a bit silly to do it like that. :)

    You have to remember that razor is essentialy c#. The easiest way I can think of is as follows:

    @{
     //    First we need the list of news
     var listOfNews = Model.news.OrderBy("newsPubDate desc");
      
     //Get latest news to be used for top news
     var latestNews = listOfNews.First();
    }

    your right just keep forgettin' it because there is some things done differently because of the razor but it could just be done like in C#.

    It will properbly stick after im finished with this solution :)

     Which means i just can do like this -.- DOH

    @listOfNews[0];
