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 98.4k17106100 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 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.

If I call MyObject o; if (objects use of != null && objects.TryGetValue(objectName, out o)) v.Property= o; then everything is fine. The following two cases however give me an error, and I'm not quite understanding why. MyObject o; if (objects != null ? objects.TryGetValue(objectName, out o) : false) v.Property= o; // <-- error CS0165: Use of Unassigned local variable 'o' and MyObject o; bool b; if (objects != null) b = objects.TryGetValue(objectName, out o); use of unassigned else b = false; if (b) v.Property = o; // <-- error CS0165: Use of Unassigned local variable 'o' In either of the last 2 cases, I don't see how o can be used unless TryGetValue is called, which means o should be initialized. Is this a bug? Or I am I missing something? Pilchie added the Area-Compilers label Jul 31, 2015 paul1956 commented Jul 31, 2015 All the VB examples show an explicate initialization of "o", even though the documentation call value an out or

I have the two lines below, just two.. and I get the following error: error CS0165: Use of unassigned local variable 'pipesStart' I'm wracking my brains over this one, as this to me is correct. void Start () { float[] pipesStart; pipesStart[0] = 0.0f; } Comment Add comment 10 |3000 characters needed characters left characters exceeded ▼ Viewable by all users Viewable by moderators Viewable by moderators and the original poster Advanced visibility Viewable by all users 1 Reply · Add your reply Sort: 2 Best Answer Answer by Piflik · Jan 14, 2013 at 09:13 PM You have declared an array, but never initialized it. What is stored in an array variable is actually just a pointer to a memory address, but you never allocated the memory you need for that aray. The vlue in your pipesStart variable is 'null', and you cannot do anything with 'null'. float[] pipesStart = new float[10]; //for an array with length ten...use whatever number you need...note: arrays cannot be resized Comment Add comment · Show 2 · Share 10 |3000 characters needed characters left characters exceeded ▼ Viewable by all users Viewable by moderators Viewable by moderators and the original poster Advanced visibility Viewable by all users curv · Jan 14, 2013 at 09:16 PM 0 Share ah.. But I'm not sure how large this array will be. Does it need to become an ArrayList at this point? Piflik · Jan 14, 2013 at 09:38 PM 0 Share If you don't know how long the array has to be, it would really be better to use a list. using System.Collection.Generic; List
