you make clases form controls like: inputbox, textbox, checkbox, radiobutton. form class contain lists of input controls.

class forminputcontrol {      public string description { get; set; } //every form input has description user, link, want form input control instance describe      public abstract object value { get; set; } }  class inputbox : forminputcontrol {      public string text { get; set; }      public overwrite object value      {          { return text; }          set { text = value string; }      } }   class form {      public ilist<forminputcontrols> { get; set; } }
