you can set cookies like 

Response.Cookies["Country"]["1"] = "US";
Response.Cookies["Country"]["2"] = "UK";

and loop through it like 

if (Request.Cookies["Country"] != null)
{
       int count= Request.Cookies["Country"].Values.Count;

       for (int i = 1; i <=count ; i++)
       {
              Response.Write(Request.Cookies["Country"][i.ToString()].ToString());
       }
}
