Does the .NET Compact Framework perform string interning?
Yes. The .NET Compact Framework interns static strings at JIT time. One can also explicitly force interning of the arbitrary string using String.Intern() method. The C# compiler will use this mechanism to force interning of the string used in the switch statement. If you compare some string against a static string(s) many times or compare some set of strings against each other repeatedly, you may benefit from string interning. There is a shortcut in the string equality check, which attempts to compare object references first, before doing character by character comparison. So, for matching interned strings the object reference will match immediately. However, you should be aware that string interning incurs some additional cost. Specifically, the memory used to store interned strings is not freed until the AppDomain is shutdown, and extra time is required to intern the string (even if the string is already interned). So, don’t use explicit string interning by default, rather use it onl
