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
Use Of Unassigned Local Variable C# Struct
that using uninitialized variables in C# is not allowed. But why do I have to 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

The program consists of five questions and the user will select one of three possible answers for each. I've assigned a number value to each radio button and when they click the Submit button, I add those values together and assign them to varResults.
