Do an action only if a condition is met in all iterations of a loop

Question

Is there a way to only trigger an action when a condition is met in all iterations of a for loop?

Example:

if ((i % 1 == 0) && (i % 2 == 0) && (...) && (i % 20 == 0)) {     Do action x } 

This is what I tried, but it didn't work as expected:

for (int b=1; b<21; b++) {     if (i % b == 0)     {         // Do something     } }

You could also use a simple LINQ query like this one:

if (Enumerable.Range(1, 20).All(b => i % b == 0))     DoAction();
