i store the values to in following manner

HttpCookie UserCookieN = new HttpCookie("userInfo");
           UserCookieN.Values["FrmType"] = Convert.ToString(Session["FrmType"]);
           UserCookieN.Values["UserId"] = Convert.ToString(UserId);
           UserCookieN.Values["BusId"] = Convert.ToString(BusId);
           UserCookieN.Values["FY"] = Convert.ToString(DdlFY.SelectedValue);
           UserCookieN.Values["RetType"] = Convert.ToString(DdlRetType.SelectedValue);
           UserCookieN.Values["NatRet"] = Convert.ToString(DdlNatRet.SelectedValue);
           UserCookieN.Values["Period"] = Convert.ToString(DdlPeriod.SelectedValue);
           UserCookieN.Expires = DateTime.Now.AddYears(30);
           Response.Cookies.Add(UserCookieN);

Now for specific "FrmType" there are multiple values of UserId,BusId,FY,RetType,NatRet,Period

At time retrieving values i want to get the values for that FrmType

I thought a cookie always stores a string. If this is not true, then it's still the case that storing a string that tells you how to build your different objects seems like the smartest way to go. Or store two values, one telling you the type, the other telling you the data to cast to that type.

Good idea about storing the type name. The object could be instantiated automatically used reflection. This is how serialization and Data Contract work. One can put a whole serialized object graph in the form of XML in one cookie value and work with it. A 5.
