Hi aspstarter,

You can do like below.

List<string> productId = new List<string> { "11", "12", "13" };
var product_Id = from id in productId select id;
Session["Product_ID"] = product_Id;
//Add id to product list.
productId.Add("14");
//Get the product list in other page.
var result = Session["Product_ID"];
