Which would be better code:

int pos = file.dmFileDescr.LastIndexOf(".", StringComparison.InvariantCultureIgnoreCase);

or

int pos = file.dmFileDescr.LastIndexOf(".", StringComparison.OrdinalIgnoreCase);

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
