App.Config - Read and Save

[Stephen Costanzo]

Looking back in the group, I figured out how to read from the appSettings
section of the configuration file.

I have default values for the application in the unlikely event that the
user deletes the configuration file. My question is this: How do I write the
defaults back out to the configuration file at run time? is this even
possible?

I understand that the System.Configuration API is read only so would I
basically have to read in the configuration file in total, create the XML
file (including the missing values) and write it back out using the normal
system.io ?

Thanks

You might look at the Enterprise Library and it's configuration
application block. It's very flexible and allows for reading and
writing.

In response to your question, you could use the System.Xml namespace to
read and write values to the app.config file.

E-mail me (tierscheiss1977 on Hotmail) and I'll send you a custom
library I made that allows Read/Write functionality to the appSettings
and userSettings section of the App.Config/Web.Config file. I use it
in all my projects that require me to use a .Config file.

maybe, when I get some time, I'll make an article on it on codeProject

appSettings is not designed to be read/write and you should not write to it.

Using System.XML is a good approach, but you should not write to app.config. Read the blogs on
MSDN and the comments in the footer of this article:
