Xml + C#?

[Storm33229]

Any good books or ebooks, sites, tutorials etc? I'd like to learn the following:
How to save(write) each variable type, how load(read) each variable type.

[Dereckson]

To write and read data in XML and C#, the best way is to design a C# class containing your data and use XmlSerializer to read/write it.

Here a sample from reading and writing a xml preference file:
Koders Code Search - MainOptions.cs - C#

See the save and load methods.

Some very interesting articles about XML and C# can be found on The Code Project - Free Source Code and Tutorials in the XML/XSLT section.

In RunUO: GDK i save and load tons of crap to xml.

Heres an example of how I save Gumps

Class Definitions:
Gump = Entire Gump
BaseGump = Components of a Gump

Saving:
Gump.cs

        public void Save(XmlWriter writer)
        {
            OnSaveStarted(this, EventArgs.Empty);

            writer.WriteStartElement("Gump");
            writer.WriteAttributeString("version", GumpVersion.ToString());
            writer.WriteAttributeString("resizable", resizable.ToString());
            writer.WriteAttributeString("dragable", dragable.ToString());
            writer.WriteAttributeString("closable", closable.ToString());
            writer.WriteAttributeString("x", x.ToString());
            writer.WriteAttributeString("y", y.ToString());
            writer.WriteAttributeString("name", name);

            foreach (BaseGump bg in Items)
            {
                writer.WriteStartElement("BaseGump");
                bg.Serialize(writer);
                writer.WriteEndElement();
            }

            writer.WriteEndElement();
            writer.Close();

            OnSaveCompleted(this, EventArgs.Empty);
        }

BaseGump.cs

        public virtual void Serialize(XmlWriter writer)
        {
            writer.WriteAttributeString("type", GetType().ToString());
            writer.WriteAttributeString("hue", hue.Index.ToString());
            writer.WriteAttributeString("index", index.ToString());
            writer.WriteAttributeString("z", z.ToString());
            writer.WriteAttributeString("x", location.X.ToString());
            writer.WriteAttributeString("y", location.Y.ToString());
            writer.WriteAttributeString("width", Width.ToString());
            writer.WriteAttributeString("height", Height.ToString());
        }

Loading:
Gump.cs

        public void Load(XmlDocument doc)
        {
            OnLoadStarted(this, EventArgs.Empty);

            XmlElement root = doc.DocumentElement;// ("Gump");
            XmlNodeList baseGumps = root.GetElementsByTagName("BaseGump");

            for (int i = baseGumps.Count - 1; i >= 0; i--)
            {
                Type type = Type.GetType(baseGumps[i].Attributes["type"].Value);
                BaseGump gump = (BaseGump)Activator.CreateInstance(type);

                string xml = baseGumps[i].OuterXml;
                char[] chars = xml.ToCharArray();
                byte[] xmlData = Utility.ConvertCharToByteArray(chars);
                XmlReader reader = XmlReader.Create(new MemoryStream(xmlData, 0, xmlData.Length));
                reader.Read();
                gump.Deserialize(reader);
                reader.Close();

                Items.Add(gump);
            }

            OnLoadCompleted(this, EventArgs.Empty);
        }

BaseGump.cs

        public virtual void Deserialize(XmlReader reader)
        {
            hue =  Hues.GetHue(XmlConvert.ToInt32(reader.GetAttribute("hue")));
            index = XmlConvert.ToInt32(reader.GetAttribute("index"));
            z = XmlConvert.ToInt32(reader.GetAttribute("z"));
            location = new Point(XmlConvert.ToInt32(reader.GetAttribute("x")), XmlConvert.ToInt32(reader.GetAttribute("y")));
            size = new Size(XmlConvert.ToInt32(reader.GetAttribute("width")), XmlConvert.ToInt32(reader.GetAttribute("height")));
        }

I still don't fully understand this, maybe because I never did any real work with gumps and so it doesn't relate to my previous RUO code...but at any rate, would you mind elaborating? I'd really like to learn this.

Best luck would be give me an example of something you are trying to save and Ill show u how I would save it.

I may haven mentioned this in other threads before; I don't remember though...anyways, I'm getting myself into further C# programming and then Game Programming via C#. So, something game related.

So in a class designated for a player: string name; //just an example.
Either way, I need to be able to save/load all variable types.
