Question

Can anyone help me on how to convert the following c# code to use linq to sql? By using linq to sql, would that execute faster or would it still be the same as below?

foreach (var a in all)
    {
        for (int i = 0; i < a.Items.Length; i++)
        {
            if (a.Items[i].Item.TruckItemID.Equals(CarItem.CarItemID))
               {
                   allItems = a.Items[i];
               }
        }
    }

Looks like you want something like:

allItems = all.SelectMany(a => a.Items)
              .Where(a => a.Item.TruckItemID.Equals(CarItem.CarItemID));

Keep in mind, though, that the execution isn’t going to speed up. LINQ will expand your query into nearly the same code.
