Code inspection: Comparison to integral constant is useless

This inspection reports a comparison between an integral value and a constant that is outside the value range of the compared type. Such a comparison has a constant result and usually points to a mistake in the condition.

Example

            class C
            {
                bool IsMatch(byte value)
                {
                    return value == 1000;
                }
            }
        

Here byte can never be 1000, so the comparison is useless.

Quick-fix

There is no dedicated quick-fix for this inspection. The usual fix is to correct the constant, change the compared type, or remove the impossible condition.
