app.config multiple values by single key [duplicate]

Answer 1

I don't think the standard key/value pair config settings can do it, but with a little more coding you can have all the configuration XML goodness you want with a custom config section.

Answer 2

Don't know if what you're asking is possible. But what I do is I concatenate values using a separator like ";" for instance.

So you have something like:

<add key="runningDays" value="Mon;Tue;Wed;Thu;Fri"/>

Then I split the value string from config using the separator to get the list of possible values for the given key.
