Question

I need to add xml-content to my application configuration file. Is there a way to add it directly to the appSettings section or do I need to implement a configSection?

Is it possible to add the xml to a CDATA element?

Answer 1

I don t think you can store the xml in the config file without implementing each of it s branches as ConfigurationElement.

You can store the full xml as CDATA though. I think this will help you in the implementation: http://devpinoy.org/blogs/jakelite/archive/2009/03/22/how-to-add-cdata-or-text-in-a-configurationelement.aspx

Answer 2

If it goes beyond standard key value pairs you ll have to create your custom section. If it is xml I don t see why you would want to store it as a CDATA blob.

Custom config sections are pretty straightforward to setup - have a look at the accepted answer on this question which covers the topic in detail.

Answer 3

You can (and I have) save XML in a configuration file as a string. It ll look like this:

<setting name="MyXml" serializeAs="String">
    <value>&lt;foo&gt;Here s my XML.  Read it and weep.&lt;/foo&gt;</value>
</setting>

To retrieve it, you d do:

string xml = Properties.Settings.Default.MyXml;
XmlDocument d = new XmlDocument();
d.LoadXml(xml);
