---------------------------- Test this class
Code
InvitationInfo invitioninfo = ModelHeper. modelBind <InvitationInfo> (Request. Form); // The InvitationInfo class is automatically bound to the value on the page.
// Print the attributes of the model.
Type it = typeof (InvitationInfo );
PropertyInfo [] ps = it. GetProperties ();
Object o = new object ();
Foreach (var p in ps)
{
Response. Write (p. Name + "value:" + p. GetValue (invitioninfo, null) + "</br> ");
}
