Re: XML adding a node in C#

Tech-Archive recommends: Speed Up your PC by fixing your registry

There's a much easier way.

// Load the machine.config file into the XML document
Uri baseUri = new Uri(typeof(string).Assembly.Location);
Uri uri = new Uri(baseUri, "config\\machine.config");
XmlDocument doc = new XmlDocument();
doc.Load(uri.AbsolutePath);


Then use XPath to find what you want:

// Finds the right node and change it to the new value.
XmlNode node =
doc.SelectSingleNode("configuration/appSettings/add[@key = 'ServerName']");
if (node != null) {
Console.WriteLine(node.InnerText);
}
