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
