Question

I have a question regarding a query in LINQ:

    DataClasses1DataContext db = new DataClasses1DataContext();
    var shpnme = from p in db.Orders
                  where p.ShipCity == "A"
                  select p.ShipName;

Am I correct in believing that the database will use the Orders database, and where in “ShipCity” any entries = “A” it will return the Shipname of that ShipCity’s entry?

Also can you do a wildcard? e.g. A*

Answer 1

Yes you are correct, this will return all ShipNames where the ShipCity equals “A” . A sort-of wildcard search can be done using .Contains(), .StartsWith() and .EndsWith()

var shpnme = from p in db.Orders
             where p.ShipCity.StartsWith("A")
             select p.ShipName;
