XML Application Help

Hey people.

I am using Xml to save and load settings from my application, and i need one help with one problem.

When i save settings, i need to be able to change the value of a node.

This is what i have done so far:

WriteSettings.Load(MainApplication.FileLocation + "settings.xml");                 XmlNodeReader ReadSettings = new XmlNodeReader(WriteSettings);                 ReadSettings.Read();                 int current = 0;                 bool Nextcurrent = false;                 XmlNode Old = WriteSettings.ReadNode(ReadSettings);                 while (ReadSettings.Read())                 {                     switch (ReadSettings.NodeType)                     {                         case XmlNodeType.EndElement:                             //I will add something here, but i need to fix the problem below                             break;                         case XmlNodeType.Element:                             //Get Account Name:                             switch (ReadSettings.Name)                             {                                 case "Name":                                                                         XmlNode Name = WriteSettings.ReadNode(ReadSettings);                                     //I tried this:                                     //Old = WriteSettings.ReadNode(ReadSettings);                                     //WriteSettings.ReplaceChild(Name, Old)                                     //But that didn't work :(                                                                         break;

But i need help with moving the value into the Xml File
