Description

In C#, having conditions that are always true (or always false) is generally a bad practice because it leads to unreachable code, logic errors, and maintainability issues.

How to Remediate

Replace true with a meaningful, dynamic condition.
Use variables, method results, or flags to evaluate logic properly.
Remove useless condition branches

Non-Compliant Code Examples

// Count cannot be negative
if (myList.Count < 0) {
    // do something
}

// use double.IsNan instead
if (x == double.NaN) {
    // do something
}

Compliant Code Examples


if (myList.Count >= 0) {
    // do something
}


if (double.isNaN(x)) {
    // do something
}
