Question

I want to reverse the output of a LINQ to SQL query.
and .Reverse() does not work, just crashes the page.

protected void Page_Load(object sender, EventArgs e)
{
    NewsDataContext db = new NewsDataContext();
    var News = from news in db.News                   
               select new 
               {
                   ID = news.NewsID,
                   kort = news.Short
               };

    foreach (var newa in News)
    {
        Panel1.
        Controls.
        Add(new LiteralControl(newa.kort + 
                               "</br>" + 
                               "<a href=Full.aspx?id=" + 
                               newa.ID + 
                               ">Read The full Article</a>"));
    }
}

Is there another way to reverse it?

I’m guessing SQL Server doesn’t know how to translate Reverse into a T-SQL command, so you’re getting an exception. You’ll probably need to pull the results of the query down from the database, then reverse it.

var News = (from news in db.News                   
               select new 
               {
               ID = news.NewsID,
               kort = news.Short
               }).AsEnumerable().Reverse();
