Executing command/instruction from a string variable

[Gancy]

I need to execute the command/instruction which is stored in a
variable. ex

string str = "drRow["userid"].ToString()"

here i need execute the instruction stored in 'str' and get the value
from executing

drGalileoToday["userid"].ToString()

I have no idea as how this could be done. Please advise

Re: Executing command/instruction from a string variable

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...

It was nominally related to either. The problem is that you posted your
message twice, rather than cross-posting (which is different from
multi-posting, what you did) it once to two different newsgroups. That
made it impossible for Jon to know, reading the framework newsgroup, that
the question had already been answered here in the C# newsgroup.
