c# - Casting Combobox.SelectedItem back to DateTime causes "Specified cast is not valid." -


i have following code appears correctly populates combobox

    class hour     {         public string shownhour {get;set;}         public datetime atime {get;set;}     }      (...)      datetime = new datetime();     = datetime.now;      list<hour> hours = new list<hour>         {             new hour{shownhour = "8:00 am", atime = new datetime(now.year, now.month, now.day, 8,0,0)},             new hour{shownhour = "8:30 am", atime = new datetime(now.year, now.month, now.day, 8,30,0)}         };      combobox1.datasource = hours;     combobox1.valuemember = "atime";     combobox1.displaymember = "shownhour";

i'm seeing "8:00 am" , "8:30 am" correctly populate , selectable in combobox. however, when attempt retrieve valuemember in combobox_selectedindexchanged event i'm getting "specified cast not valid." error. can't seem retrieve following code.

datetime starttime = (datetime) combobox1.selecteditem;

in debugger, i'm seeing atime combobox.selecteditem , appears formatted datetime type can't seem cast back. approaching problem incorrectly?

solution: @cj s pointed out below, combobox.selecteditem returning hour type thought returning data of hour.atime of type datetime. using solution given gave correct information.

you can't cast string datetime. use datetime.parse instead.
