Not All Code Paths Return A Value In Lambda Expression
returning error “not all code paths return a value” up vote 17 down vote favorite 6 I'm trying to write code that returns whether or not a given integer is or is not divisible evenly by 1 to 20, but i keep receiving "error CS0161: 'ProblemFive.isTwenty(int)': not all code paths return a value" Please help. Here is my code: public static bool isTwenty(int not all code paths return a value unity num) { for(int j = 1; j <= 20; j++) { if(num % j != 0) { return false; } else if(num % j == 0 && num == 20) { return true; } } } c# share|improve this question asked Jan 17 '14 at 20:47 user115185 89114 migrated from programmers.stackexchange.com Jan 17 '14 at 22:48 This question came from our site for professional programmers interested in conceptual questions about software development. 5 Your code doesn't make sense but the error message is quite clear. You need to return a value even if both your if conditions are false for 20 iterations. –ChaosPandion Jan 17 '14 at 20:52 4 You're thinking like a human, not a compiler. The compiler doesn't know what you are thinking, or how the logic is supposed to flow (past optimization). What happens if a value doesnt match either 'if'? –GrandmasterB Jan 17 '14 at 21:08 add a comment| 6 Answers 6 active oldest votes up vote 34 down vote You're missing a return statement. When the compiler looks at your code, it's sees a third path (the else you didn't code for)

"return" is final. It will quit the function at that point, returning just the first value found in the loop. If there is nothing in dirs (an empty collection) it cannot return anything, so falls out of the foreach loop having done nothing, and hence the error. If there is nothing in the "dirs" collection, what is returned? The simple fix is to add return after the foreach, as a "catch-all" using System; using System.Data; using System.IO; using System.Data.SqlClient; using System.Data.SqlTypes; using M
