Question

I have a LINQ2SQL Query:

 //Pulling the Product_ID from the PlanMaster Table from WebEnroll DB!
                var tr = from s in dt.PlanMasters
                         where s.PlanName == productName
                         select new
                         {
                             s.Product_ID
                         };

This is pulling Product_ID which is working good. Now I want to ADD a record into another LINQ statement which is here:

                CommissionsV2DataContext cv = new CommissionsV2DataContext();
                Entity_Product_Point ev = new Entity_Product_Point();
                ev.Entity_ID = getEntity;
                ev.Product_ID = tr.; ?????

I want to store the variable which I am getting from tr (that is Product_ID) to ev.Product_ID.

How should I convert an object to an INT? Thank you!

Answer 1

The problem is that your first query returns a collection of objects with an integer property, not a single integer. You can change your query to this instead:

var tr = (
    from s in dt.PlanMasters
    where s.PlanName == productName
    select s.Product_ID).First();

Or, more cleanly, IMO:

var tr = dt.PlanMasters.First(s => s.PlanName == productName).Product_ID;
