access web.config using wpf

Would anyone be so kind as to help me figure out how to open a web.config file from a wpf thick client. I have a wpf form (not a silverlight app) that I would like have the ability to browse to a directory ( c:\test\web.config ) and then load custom keys from the appSettings section of the selected web.config file. Example Bind a field within my form to Path=Version

Within the web.config file Version would be identified as:

<add key=开发者_如何学编程"Version" value="1.0 />

Thanks in advance

I usually prefer to use one of the ConfigurationManager methods like this one:

Or there is the old style Xml with XPath:

XmlDocument webConfig = new XmlDocument();
webConfig.Load(dllConfigFileName);
XmlNode someNode = webConfig.SelectSingleNode("//configuration/appSettings/add[@key='someKey']");

Or the newer LINQ to XML:

XDocument document = XDocument.Load(configFileFullName);
XElement configurationElement = document.Element("configuration");
XElement appSettingsElement = configurationElement.Element("appSettings");
List<XElement> configSettings = new List<XElement>(appSettingsElement.Descendants("add"));
