Now
I want to result in XML like below(Basically just adding another level inside of xml):

<Quotes>
  <Quote>
    <GenericInfo>
    <ID>61c6a1d9-bb7a-4525-880c-81e7eaae284e</ID>
    </GenericInfo>
  </Quote>
</Quotes>

How can I do that within my codes?

Thanks

try this:

XmlDocument doc = new XmlDocument();
            doc.Load(@"your path here");
            XmlNode childNode = doc.SelectSingleNode("/Quotes/Quote/ID"); 
            XmlNode pnode = childNode.ParentNode;
            childNode.ParentNode.RemoveChild(childNode);
            XmlNode new_node = doc.CreateElement("GenericInfo");
            new_node.AppendChild(childNode);
            pnode.AppendChild(new_node);
            doc.Save(@"your path here");

That was not the original question. Also you did not post the complete code. Where do you call your Save method? Where is class generic defined? Does AddChild belongs to that class?  Otherwise I did give you a solution to your question. It words and you can easily change the code to fit in your class
YZlatCommented:
 public void AddChild(XmlDocument doc, XmlNode parentNode, string elementName, string value)
        {
            XmlNode node = doc.CreateElement(elementName);
            node.InnerText = value;
            parentNode.AppendChild(node);

        }

        public  bool Save(string fileLocation)
        {
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load(fileLocation);
                XmlNode childNode = doc.SelectSingleNode("/Quotes/Quote/ID"); // apply your xpath here
                XmlNode pnode = childNode.ParentNode;
                childNode.ParentNode.RemoveChild(childNode);
                XmlNode new_node = doc.CreateElement("GenericInfo");

OK, now I see what the problem is - you are using a web application. I did it with windows app. The code is correct and if you run your web application from your computer, it works. It worked for me when I copied the code you used. The problem is that when application is on web server and the XML file you are trying to modify is not local to application (is not on the same physical server), it will not work. That's just how it is for security reason - so that web apps cannot modify files on your hard drive
ITsolutionWizardAuthor Commented:
An entire codes are in my computer. not a server. and it returns false. everything include the xml is in  the same directory. there is no security reason.
YZlatCommented:
Well, the code worked for me just fine in both windows and web apps
