Question

Let’s say I have five integer values that must all be unique.

int a;
int b;
int c;
int d;
int e;

Obviously I could do something like this to test for that:

if (a == b) {
    return false;
} else if (a == c) {
    return false;
} else if (a == d) {
    return false;
}
//etc etc

But that makes for extremely messy code in my opinion. Is there a “cleaner” way to do this?

Answer 1

Probably a bit of overhead, but you could do:

new [] {a, b, c, d, e}.Distinct().Count() == 5
