Question

I have written the linq query like:

    NorthwindContext context = SqlCE;
   var query = context.Destinations.Where(i => i.Id >= 1).Select(i => new {
                    id = i.Id,
                  name = i.Destination
       }).ToArray();

   public NorthwindDataContext SqlCE
    {
        get
        {
            AppDomain.CurrentDomain.SetData("SQLServerCompactEditionUnderWebHosting", true);
            string connectionString = @"Data Source=|DataDirectory|\Database1.mdf";
            return new NorthwindDataContext(connectionString);
        }
    }

I have connected to sqlserver northwind.mdf file. I have values in the table also still i am getting null reference exception. How can i rectify this. How to get values in to the query.

You’ll probably need something like that:

using (var context = new NorthwindContext()) 
{
    var query = context.Destinations.Where(i => i.Id >= 1).Select(i => new {
                id = i.Id,
              name = i.Destination
    }).ToArray();
 }

Although there may be more you may be missing (e.g. connection strings, etc).
