XmlSerialization doesn't write to file

Hi,

I have been programming in Java for a few years and have just started learning C#.
I have created the following code:

Code:

---

public static void WriteToFile(Song song, String filename)
        {
            Console.WriteLine("About to write to file");
            try
            {
                XmlSerializer writer = new XmlSerializer(typeof(Song));
                StreamWriter file = new StreamWriter(filename);
                writer.Serialize(file, song);
                file.Close();
                Console.WriteLine("Wrote to file successfully");
            }
            catch (Exception e)
            {
                Console.WriteLine(e.Message);
            }
        }

---

But the resulting file only contains:

Code:

---

<?xml version="1.0" encoding="utf-8"?>
<Song xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" />

---

What am I doing wrong?

Thanks

Personally i'm using the TextWriter version

Code:

---

if (FileList.myFiles[0].Count > 0 && Global.bSerialEnable)
                    {
                        foreach (long key in FileList.myFiles[0].Keys)
                        {
                            tempdataitems.Add(new DataItem(key.ToString(), FileList.myFiles[0][key].ToString()));
                        }

                        XmlSerializer serializer = new XmlSerializer(typeof(List<DataItem>));
                        StringWriter sw = new StringWriter();
                        XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                        ns.Add("", "");

                        serializer.Serialize(sw, tempdataitems, ns);
                        string path = sMyPath + @"\data.bin";
                        File.WriteAllText(path, sw.ToString(), Encoding.Unicode);
                        sw.Dispose();
                    }

---

Where DataItem is this (only used for serialization)

Code:

---

public class DataItem
    {

        public string Key;

        public string Value;

        public DataItem(string key, string value)
        {
            Key = key;
            Value = value;
        }
        public DataItem()
        {

        }
    }

FileList is a personnal class. sMyPath is my application path

Managed to sort it out. Was due to my incorrect implementation of getters and setters, I think.

Most likely. Only properties with public setters and getters that are flagged with an xml attribute will get saved.
