Assembly: Gendarme.Rules.Performance
Version: 2.10

This rule checks for methods that are using the literal "" instead of the String.Empty field. You'll get slighly better performance by using String.Empty. Note that in some cases, e.g. in a switch/case statement, you cannot use a field, so "" must be used instead of String.Empty.

Bad example:

string s = "";

Good example:

string s = String.Empty;
