I'm looking for a quick way (in C#) to determine if a string is a valid variable name. My first intuition is to whip up some regex to do it, but I'm wondering if there's a better way to do it. Like maybe some kind of a secret method hidden deep somewhere called IsThisAValidVariableName(string name), or some other slick way to do it tha...

Is anybody aware of a good strategy t...
