Hi! I wrote this code in class.cs. But I want call it’s from default.aspx.cs

public ArrayList GetInfos(string NAM)
{
    ArrayList list = null;
    if (ViewState["ArrayData"] == null)
    {
        list = new ArrayList();
        string str = ConfigurationManager.ConnectionStrings["conString"].ConnectionString;
        SqlConnection con = new SqlConnection(str);
        SqlCommand cmd = new SqlCommand("SELECT SURNAME,NAM,LASTNAME,BIRTHDAY,ADDRESS FROM INFO WHERE NAM=" + NAM, con);
        con.Open();
        SqlDataReader rdr = cmd.ExecuteReader();
        while (rdr.Read())
        {
            list.Add(string.Join(";", rdr["SURNAME"], rdr["NAM"], rdr["LASTNAME"], rdr["BIRTHDAY"], rdr["ADDRESS"]));
        }
        ViewState["ArrayData"] = list;
    }
    else
    {
        list = ViewState["ArrayData"] as ArrayList;
    }
    return list;
}
