#region parentitem public class baseheaderfooteritem { public string title { get; set; } public string entitle { get; set; } public hyperlink link { get; set; } public int level { get; set; } } #endregion #region headerfooter public class headerfooter : baseheaderfooteritem { public list<category> descendants { get; set; } } #endregion #region headerfooter public class category : baseheaderfooteritem { public list<show> descendants { get; set; } } #endregion #region header public class show : headerfooter { public string imagepath { get; set; } public string mobilelink { get; set; } public string mobilelinktarget { get; set; } } #endregion #region tvguid public class tvguid : show { public string date { get; set; } public string time { get; set; } public int isactive { get; set; } public int noprogram { get; set; } } #endregion
