Add array to key in web.config

Question

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

<add key="email" value="emails["[email protected], [email protected]"] /> 

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="[email protected];[email protected]" />
