XML file processing removes comments

This snippet <!--Please don't delete this-->

is part of my XML file. After running this method, the resulting XML file no longer contains this snippet <!--Please don't delete this-->

. Why is this?

Here's my method:

         XmlSerializer serializer = new XmlSerializer(typeof(Settings));
         TextWriter writer = new StreamWriter(path);
         serializer.Serialize(writer, settings);
         writer.Close();

Well, this is quite obvious:

  • XmlSerializer

    will parse the XML file and extract all instances from it Settings

    - your comment will not be part of any of these objects
  • when you unsubscribe again, only the contents of the objects will be unloaded again Settings

Your comment will fall through the cracks, but I don't see any way to save this comment while you are using the XmlSerializer approach.



What you need to do is use the XmlReader / XmlWriter instead:

XmlReader reader = XmlReader.Create("yourfile.xml");
XmlWriter writer = XmlWriter.Create("your-new-file.xml");

while (reader.Read())
{
   writer.WriteNode(reader, true);
}

writer.Close();
reader.Close();

This will copy all xml nodes including comments to a new file.

<!-- -->

means a comment in XML. You are posting an object to XML objects, the objects have no comments as they are compiled at compile time.



That is, the object Settings

(which is probably the de-serialized form of your XML .config) does not store comments in memory after de-serialization, so they will not be serialized either. There is nothing to do with this structure behavior, as the built-in mechanism for de-serializing comments is not used using XmlSerializer

.
