I am having a appsetting file as below.

HTML

<appsettings>
<add key="test1" value="chk1" />
<add key="test2" value="chk2" />
<add key="test3" value="chk3" />
</appsettings>

but the configuration section is missing in the appsetting file as it has been refered from the web.config file.

I want to read the above appsetting file as xml and add a <configuration> arround the appsetting node to read the keys from an external application.

After reading i want to remove that configuraion node
can any body help me out to add and remove the configuration node arround appsetting node ?

As far as I know, you cannot change the appsettings in the config /file/ but you can load an alternative configuration. I think you can write one at runtime and use that instead.
The ConfigurationManager is readonly at runtime.

Without configuration node, this xml will not be treated as a config file by ConfigurationManager. You can just read it in an XmlDocument (Load(string filepath)) and modify it the way you want (and then save() it).

However, Can you please let us know, what are you trying to achieve by doing this. May be the we can figure out a more elegant solution.

You can add and remove sections from a valid configuration file by following the link below:

Is this a .net configuration file or your own, custom configuration file?

Please try below code for your requirement...

XDocument xmlDoc = XDocument.Load(filePath);
bool isExists = (from data in xmlDoc.Element("appsettings")
				select data).Any();
if (!isExists)
{
	    XmlElement parent = xmlDoc.CreateElement("configuration");
            //Now find that appSettings node and append it to parent Element
}

//Delete Node
XmlNodeList newXMLNodes = xmlDoc.SelectNodes("/configuration/appsettings");
foreach (XmlNode child in newXMLNodes)
{
  child.ParentNode.RemoveAll();
}
