Since the program already terminates with Environment.Exit(0)? Hope ya'll can give me some pointers :) Thanks. c#

Just initialize queue to null when you declare it. Queue queue = null; share|improve this answer edited Mar 9 '13 at 1:14 Zaid Masud 7,20634369 answered Nov 1 '08 at 20:35 tvanfosson 350k65568700 add a comment| up vote 9 down vote The compiler doesn't know that Environment.Exit() does not return. Why not just "return" from Main()? share|improve this answer answered Nov 1 '08 at 20:35 Brian 95.3k11187264 I prefer to use Environment.Exit with a non-zero error status in case the program is called from a script. That way the script can know whether the program was successful or not by checking the exit status. –tvanfosson Nov 1 '08 at 20:51 4 Change the return type of main to int and return the status. –Scott Langham Dec 5 '08 at 1:18 add a comment| up vote 8 down vote A couple of different ways to solve the problem: Just replace Environment.Exit with return.
