Question

I was wondering if its possible to put an array as a value in a key…example

<add key="email" value="emails["[e-mail], [e-mail]"] />

Would that syntax work?

Answer 1

With ConfigurationManager.AppSettings you can only retrieve scalar values. For your example, if you seperate your emails with a semicolon, you can do:

string[] emails = ConfigurationManager.AppSettings["email"].Split(';');

with the web.config

<add key="email" value="[e-mail];[e-mail]" />
