Help editing Xml file in C#

[jadughar]

Hi I'm trying to modify an Xml file. This is the content of the Xml. The problem is that after changes, it will creates a copy of the content of the Xml file without changing the old content. Before changes :

After changes :

The code is :

    //xml document object
    System.Xml.XmlDocument xdoc = new System.Xml.XmlDocument();
    
    FileStream reader = new FileStream(this.\_XmlFilePath, FileMode.Open, FileAccess.ReadWrite);

    xdoc.XmlResolver = null;
    
    //load the xml file
    xdoc.Load(reader);

    System.Xml.XmlElement Node = (System.Xml.XmlElement)xdoc.DocumentElement.SelectSingleNode("//configuration/connectionStrings/add\[@name=\\"Application.Properties.Settings.DBConnectionString\\"\]");
    if (Node != null)
    {
        //key found, set the value
        Node.Attributes.GetNamedItem("Source").Value = "C:\\DataDabe\\DB.mdb";

        //finally, save the new version of the config file
        xdoc.Save(reader);
        reader.Close();
    }

yes it suppose to do, because you are saving the xml in same stream. try this

    if (Node != null)
    {
        //key found, set the value
        Node.Attributes.GetNamedItem("Source").Value = "C:\\DataDabe\\DB.mdb";

        //finally, save the new version of the config file
        **_reader.Position = 0;_**
        xdoc.Save(reader);
        reader.Close();
    }

okay do this

    System.Xml.XmlDocument xdoc = new System.Xml.XmlDocument();
    xdoc.XmlResolver = null;
    
    //load the xml file
    xdoc.Load(this.\_XmlFilePath);

    System.Xml.XmlElement Node = (System.Xml.XmlElement)xdoc.DocumentElement.SelectSingleNode("//configuration/connectionStrings/add\[@name=\\"Application.Properties.Settings.DBConnectionString\\"\]");
    if (Node != null)
    {
        //key found, set the value
        Node.Attributes.GetNamedItem("Source").Value = "C:\\DataDabe\\DB.mdb";

        //finally, save the new version of the config file
        xdoc.Save(this.\_XmlFilePath);
    }
