           }
           else
           {
               product.UpdatedBy = Convert.ToInt32(HttpContext.Current.User.Identity.Name);

C#

// Create a new Order object.
Order ord = new Order
{
    OrderID = 12000,
    ShipCity = "Seattle",
    OrderDate = DateTime.Now
    // …
};
// Add the new object to the Orders collection.
db.Orders.InsertOnSubmit(ord);
// Submit the change to the database.
try
{
    db.SubmitChanges();
}
catch (Exception e)
{
    Console.WriteLine(e);
    // Make some adjustments.
    // ...
    // Try again.
    db.SubmitChanges();
}

Use above code as sample, try this way.
Hope this will help !!!
