I know I didn't explicitly initialize it but due to Default Value Table a value type is initialized with 0 anyways. The reference also reminds me: Remember that using uninitialized variables in C# is not allowed. But why do I have to http://stackoverflow.com/questions/9233000/why-compile-error-use-of-unassigned-local-variable do it explicitly if it's already done by default? Wouldn't it gain performance if I wouldn't have to do it? Just wondering... c# .net compiler-construction share|improve this question asked Feb 10 '12 at 18:41 theknut 59521231 Can anyone help me with the headline? Couldn't find a fitting for this one :-S –theknut Feb 10 '12 at 18:44 I have a local struct, never initialized, compiles with no errors. Today I created a different struct, treated identically, got "uninitialized local variable error". All its members were set to a value before use, but I could not first set it to null, since it was 'just' a struct. The struct that compiled contained only ints, bools and strings. The one that gave the error also contained DateTimes. "MyStructType myStruct = new MyStructType();" killed the error. Not the first time I've been bitten by missing something a few levels down. –mickeyf Jun 2 at 19:14 add a comment| 9 Answers 9 active oldest votes up vote 55 down vote accepted Local variables aren't initialized. You have to manually initialize them. Members are initialized, for example: public class X { private int _tmpCnt; // This WILL initialize to zero ... } But local variab

Note that I code using C#. I am working on a game much in the vein of Plants VS Zombies. Everything is going VERY nice so far, but I have a problem making the canonball projectiles (catapult-like motion) to always aim at the closest enemy on the same row (I use of unassigned coded snap-to-grid for drag-and-drop of characters/items). I can easily make everything working, but with an overuse of IF statements, which is definetely bad because I will have to write tons of conditional code for every stage and every enemies wave. So the problem comes when I try to get rid of overusing all those IF statements; I borrowed a function directly explained in the Unity documentation (ref: here) that checks for the closest enemy. I need to know the closest enemy because my bezier/catapult code needs Start, Mid and End (target) points to create the arc motion for the GameObject, and because I always want the target point of the arc to be the closest enemy on the same row. However, I get an error "Error CS0165: Use of unassigned local variable 'closest'". I think this can have something to do with the fact that the variable can be null, however I can't figure out what, how and where to define it... I tried to paste my code with the code button, but seems like I cannot get it to work properly so please check it on pastebin over here. edit(copied, reformated and extracted relevant parts of the

It's quick & easy. error CS0165 and structs P: n/a John Aldrin Hi, I'm confused about when compiler error "CS0165: Use of unassigned local variable" should be generated. If I have a struct w/public fields the error is not generated when the new operator is not used. If there are no public fields the error is generated. Does this make sense? Ex 1 Public Fields public struct TstStruct { public int x; public int y; public int X { get { return x;} set { x = value;} } public int Y { get { return y;} set { Y = value;} } }; // No compile errors static void TestStruct() { TstStruct tstStruct; // new operator not used tstStruct.x = 100; tstStruct.y = 200; tstStruct.X = 100; tstStruct.Y = 200; int aValue = tstStruct.X; } Ex 2 No Public Fields public struct TstStruct { private int x; private int y; public int X { get { return x;} set { x = value;} } public int Y { get { return y;} set { Y = value;} } }; // Yes compile errors static void TestStruct() { TstStruct tstStruct; tstStruct.X = 100; // Compile error here tstStruct.Y = 200; int aValue = tstStruct.X; } Thanx jra Nov 15 '05 #1 Post Reply Share this Question 1 Reply P: n/a Nick Malik makes perfect sense to me. The compiler doesn't want to generate an error if there is a *Remote Possibility* that your code is correct as coded. If you have public fields, someone COULD create the object correctly and assign values to those fields before any internal code is called (especially since your example doesn't include a constructor). On the other hand, if the fields are private, the compiler now *Knows* that no outside code is initializing those fields... and therefore raises the error. I suppose that you could say that the compiler should warn you in the first case, but it doesn't. (Perhaps there's a flag somewhere that tells it to... ;-o) Both of your examples are bad
