c# - How would I define "GetDataFromNumber" so that my class contains a definition? -
my code gets error saying:
'eagle_eye_class_finder.getschedule' not contain definition 'getdatafromnumber' , no extension method 'getdatafromnumber'.

} }
your getdatafromnumber method non-static method inside idnumber inner class itself, hence can accessed idnumber object e.g idnumbers[0].getdatafromnumber(text);
you move getdatafromnumber method out of idnumber class , getschedule class instead.
