How to add newline character in app.config?

Question

I'm not getting as how to write a message in app.config which consists of two or more lines. My usual code in config file is :

add key="msg_test" value="This is test message."        

And I read it in c sharp code like :

ConfigurationSettings.AppSettings[msg_test]; 

And I want to write something like

add key="msg_test"      value="This is test message \n are you sure you want to continue?" 

Answer 1

You can just use line breaks in the value:

add key="msg_test" value="This is test message." 

You can also use XML encoded characters:

add key="msg_test" value="This is
test message." 

(I have tested both, and they work.)

Answer 2

The XML escape for newline is 
, so this should work:

<add key="msg_test"  value="This is test message &#xA; are you sure you want to continue?">
