c# - Convert a user's 24h input to 12h -

so reason comes error message saying 'no overload method'parseexact' takes 1 argument'. know i've done wrong?

 static void runtimeconverter() {     double arrivaltime;  arrivaltime = getarrivaltime();  string time = datetime.parseexact(arrivaltime).tostring("hh:mm tt");  console.writeline("equals " + time); }   static double getarrivaltime()      {         console.writeline             ("enter time in 24 hour format convert 12hour");         string timeselected = console.readline();         int timeinput = int.parse(timeselected);         return timeinput;     } 

so reason comes error message saying 'no overload method'parseexact' takes 1 argument'. know i've done wrong?

yes. can not read or refuse process error message compiler shows - exact in wrong.

your code:

datetime.parseexact(arrivaltime)

that 1 argument. compiler says wrong.

if check documentation:

http://msdn.microsoft.com/en-us/library/w2sa9yss(v=vs.110).aspx

it shows method as:

public static datetime parseexact(     string s,     string format,     iformatprovider provider ) 

that 3 arguments. give one. not more obvious. fix code.
