c# - Why can't I return only in a nested body of my Method and not be forced to return in the scope of the main method? -

-

why if declare return type on method, have specify return in scope of method? meaning, if have if/switch in method can't specify return there "alone" , not in main method body? way around assign value returned nested procedure variable , return variable in main body of method?

example:

public int getnum() {    var = 1;    switch(a)    {       case 1:         return 1 + 5;       default:         return a;    }  return a;   //why must specify return if going hit switch statement              //and return int. }

if have default, that's not necessary.

if don't have default, need outer return in case none of cases execute.

i define tasks using nsdictionary, i'd save in plist file (i didn't have luck core data far), got stuck @ 2 points: -- when using initwithobjectsandkeys: can change data type number or boolean, using nsdate's numberwithint: , numberwithbool: methods, respectively. can't seem find method change type date though. couldn't find in documentation. -- second problem ran nested arrays. how can add them dictionary? i have uploaded picture here of trying achieve. thank in advance! do mean nsnumber 's +numberwithint: , +numberwithbool: methods, not nsdate ? it's nsnumber defines methods. to convert number date, depends on number is. if it's unix timestamp, [nsdate datewithtimeintervalsince1970:thetimestampinseconds] . as adding nsarray objects dictionary: [yourdictionary setobject:yourarray forkey:@"somekey"]; you'll have post code if need more question isn't clear.
