c# is not an interpreted language like javascript etc, so there is no easy
way to do this. In some cases you can use the compiler directly, but this is
not usually appropriate and there are security issues (that string could be
anything) - and scoping issues (how to supply drRow to an arbitrary block of
code).

In short - I don't think that this is the right approach to start with.
There may be more suitable approaches if you can tell us *why* you want to
do this. For example, if you just new "userid" and wanted to get the string
contents, then it would be trivial...

Please don't multi-post. I wouldn't have answered the question in the
framework group if I'd seen that Marc had already provided a perfectly
good answer here.
