string split in c#

Question

I have strings like this:

    00123_MassFlow
    0022245_VOlumeFlow
    122_447_Temperature

I have to split these strings with _

Answer 1

"122_447_Temperature".Split('_').Last();

If you don't mind the extra overhead of creating an array and throwing away a bunch of strings. It won't be as fast as using LastIndexOf and Substring manually, but it's a ton easier to read and maintain, IMO.
