Question

I have a table in my database. I want to get the maximum value of a column named NumOfView. I used this code:

var advert=(from ad in storedb.Ads
             where ad.AdScope == "1" 
             select ad.NumOfView).Max();

It works but when there are two or more same maximum values it doesn’t work and this message appears:

Sequence contains more than one element

What should I do now? Your answers will be very helpfull. Thanks

You could try the following:

 var advert = storedb.ads
                    .Where(a => a.AdScope == "1")
                    .OrderByDescending(a => a.NumOfView)
                    .First();
