Commenting/uncommenting segments easily in C#

I use stuff like this quite often. Here's an extension, for switching quickly between two different code blocks:

//*
doSomethingOneWay();
/*/
doSomethingAnotherWay();
//*/

As is, that will execute doSomethingOneWay(). To run doSomethingAnotherWay(), just take off the first '/':

/*
doSomethingOneWay();
/*/
doSomethingAnotherWay();
//*/

Incredibly useful stuff for trying out two different ways to do something. Of course, if you use block comments anywhere in there, then it all gets messed up... I suppose the better way to do it would be to just use #if/#else/#endif but I like doing it with comments for some reason...

#if 1
doSomethingOneWay();
#else
doSomethingAnotherWay();
#endif

And just change the 1 to 0 to switch between them...
