Using ``++string.Equals++`` to determine if a string is empty is significantly slower than using ``++string.IsNullOrEmpty()++`` or checking for ``++string.Length == 0++``. ``++string.IsNullOrEmpty()++`` is both clear and concise, and therefore preferred to laborious, error-prone, manual null- and emptiness-checking. == Noncompliant Code Example ---- "".Equals(name); // Noncompliant !name.Equals(""); // Noncompliant name.Equals(string.Empty); // Noncompliant ---- == Compliant Solution ---- name != null && name.Length > 0 // Compliant but more error prone !string.IsNullOrEmpty(name) string.IsNullOrEmpty(name) ----
