Hello,
I'm using RegEx for some file processing. All's well except that the expression is large, with a small portion that needs to change at each call. This means that the expression can no longer be compiled, at least from my understanding of the documentation.
Two questions...
1) is there a workaround to compile a regular expression on the fly AND be able to unload the assembly afterwards?
2) is there any rough figure about the performance advantage between a compiled expression and one that is not?

Thanks in advance
