writing in app.config

[sam]

Hi,

I use string sValue = ConfigurationManager.AppSettings["MyKey"] for reading
a value in my app.config, section AppSettings.
Ho to write in it for example to create a key and assign a value like this ?
ConfigurationManager.AppSettings["ANewKey"]="my value in app.config";

Thanks for help.

Short answer: Don't. app.config is in the same directory as your
executable, which means there's a good chance you won't have write
access in a properly secured environment (or on Vista in general, I
believe). Look up user.config for saving user-configurable settings.
user.config ends up in the Application Data subdirectory tree by
default.

The docs also hint that runtime write access to app.config is
explicitly denied, at least in VS2005.
