CRR0002 - Suspect variable reference in a For-loop condition

Feb 28, 2025

This analyzer detects mistakes made in the for loop condition expression. For instance, the for loop can increment one variable, but test another. This may lead to incorrect number of iterations or even an infinite loop. It’s easy to make such mistake when editing a copy of another loop.

csharp

for (int i = 0; i < n1; i++) {
    for(int j = 0; i < n2; j++) { // CRR0002
        // ...
    }
}

In the example above, the inner loop should test the variable “ j “.

csharp

for (int i = 0; i < n1; i++) {
    for(int j = 0; j < n2; j++) {
        // ...
    }
}
