将数组添加到web.config中的键

Question

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

<add key="email" value="emails["email1@email.com, email2@email.com"] />

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="email1@email.com;email2@email.com" />
