I know how to read content from an XML file, but I don't know how to write something into it.

For example, I read an integer variable from an XML file and modify it. After modifying, I want to save the integer variable to the same XML file. The old integer value must be replaced with the new value. My game runs on Windows 7.

I load the XML file with this code:

protected override void LoadContent()
{
    scorexml = Content.Load<List<Gamescore>>("Score");
    foreach (Gamescore score in scorexml)
    {
        score.Load(Content);
    }   
}  


public class Gamescore
{
    int score;
    public int Score
    {
        get { return score; }
        set { score = value; }
    }
}

    In your example you can use auto-properties to save you some typing: `public int Score { get; set; }` – Tim S. Jul 16 '12 at 13:45

I can suggest you two approaches.

  1. Using a class that represent your XML and that implements the ISerializable interface:
    • deserialize the xml into an object, instance of the class.
    • process the data (setting integer values or whatever).
    • serialize the object into the xml file.
  2. Using Linq to XML to process the XML:
    • create a XDocument from xml file.
    • process the XDocument with Linq.
    • save the XDocument into the xml file.
