Not all Paths return a value : C# -

forgive me if basics, have following function

private reportoption getreportoptions(int id, datarow dr) {     string reporttype = getvalue(dr, "report type");     if (reporttype == "single")     {         getsinglereportoptions(id, dr);                    }     else     {         getmultiplereportoptions(id, dr);     } } 

now both functions getsinglereportoptions , getmultiplereportoptions returning value of type reportoption.

still gives me error

not code paths return value

can tell me why? how should structure function or make change in 2 helper functions?

the method getreportoptions doesn't return results of either getsinglereportoptions or getmultiplereportoptions. calls methods , ignores return values. preface both method calls return method return results of methods.
