ReSharper 2016.3 Help

Code Inspection: Loop control variable is never changed inside loop

In the following code snippet

int j = 0; for (int i = 0; i < 10; j++) { ... }

the for loop variable is not varying. This causes the loop to execute indefinitely (unless for instance an exception occurs). ReSharper warns us that there is nothing constraining the loop – it either fails immediately or it runs indefinitely. The error in the code above is caused by incrementing the incorrect variable ( j as opposed to i).
