Is it good practice to compare C# string with '=='?

Question

Is it a good practice to compare strings with ==? Is there an equivalent to s1 == s2 in terms of Compare and Equals methods on string. If one uses those methods, without specifying CultureInfo FxCop will give a warning, is that a real problem?

Answer 1

The == Operator is an ordinal, culture unaware string compare. Its using the same internal call as .Equals, and is just fine for the "usual" string compare stuff.

If you need Culture-Aware comparings (eg. For GUI purposes ) , like german double-s or ß, use

CultureInfo ci = new CultureInfo("de-DE");
String.Compare("Strasse", "Straße", true, ci)
