Use Of Unassigned Local Variable C# Array
them; it only takes a minute: Sign up C# error: Use of unassigned local variable up vote 22 down vote favorite 1 I'm not sure why I'm getting this error, but shouldn't this code compile, since I'm already checking to see if queue is getting initialized? public static void Main(String[] args) { Byte maxSize; Queue queue; if(args.Length != 0) use of unassigned local variable c# for loop { if(Byte.TryParse(args[0], out maxSize)) queue = new Queue(){MaxSize = maxSize}; else Environment.Exit(0); } else { Environment.Exit(0); } for(Byte j = 0; j < queue.MaxSize; j++) queue.Insert(j); for(Byte j = 0; j < queue.MaxSize; j++) Console.WriteLine(queue.Remove()); } So if queue is not initialized, then the for loops aren't reachable right? Since the program already terminates with Environment.Exit(0)? Hope ya'll can give me some pointers :) Thanks. c# initialization share|improve this question edited Nov 2 '08 at 0:17 Blair Conrad 98.3k17106100 asked Nov 1 '08 at 20:33 jkidv 1,11131212 6 I can't give you any pointers, but I hope you can get a handle on this one. –wprl Nov 1 '08 at 20:40 add a comment| 5 Answers 5 active oldest votes up vote 65 down vote accepted The compiler doesn't know that the Environment.Exit() is going to terminate the program; it just sees you executing a static method on a class. Just initialize queue to null when you declare it. Queue queue = null; share|improve this answer edited Mar 9 '13 at 1:14 Zaid Mas
