Hi.

 i try to read the data in my .xml file.

   protected void Page_Load(object sender, EventArgs e)
    {
        
        XmlDocument doc = new XmlDocument();
        doc.LoadXml("<settings>" +
                    <imagessize>" +
                    </imagessize>" +
                    <frontpage></frontpage>" +
                    </settings>");

    XmlTextReader reader = new XmlTextReader(Server.MapPath("App_Data\\Settings.xml"));
        reader.MoveToContent(); 


        XmlNode Settings = doc.ReadNode(reader);



 
        doc.DocumentElement.AppendChild(Settings);

        string StrFront = Convert.ToString((Settings));

        TextBox1.Text = StrFront;
    }

But i don't get any longer, how to write out the data in the xml file? 

Hi Frozzare ,

First of all ,I want to say there is one sample which almost the same with your code : http://msdn.microsoft.com/en-us/library/system.xml.xmldocument.readnode.aspx

And I notice that :

Frozzare:

string StrFront = Convert.ToString((Settings));

The code can get the name of Class instead of it's innerText . You can try to use Settings.OuterXml.
