Get first item in list from linq query

Question

I wish to get just the very first record I realize the the \"Take() will not work.

So I have a List that queries another list

List etch         


        

Answer 1

Use the FistOrDefault method to safely return the first item from your query, or null if the query returned no results:

var result =
    (from vio in AddPlas
     where etchList.Any(vioID => vio.Key.Formatted.Equals(vioID))
     select new
     {
        EtchVectors = vio.Shapes.FistOrDefault()
     })

Or equivalently:

var result = AddPlas.Where(x => etchList.Any(y => x.Key.Formatted.Equals(y)))
                    .Select(x => new { EtchVectors = x.Shapes.FistOrDefault() });
