XML Deserialize an array that is not in an array container

Question

I have an XML file (for Tiled tile editor): (snippet of the xml)

<map version="1.0" orientation="orthogonal" renderorder="right-down" width="64" height="64" tilewidth="32" tileheight="32" nextobjectid="1">
 <tileset firstgid="1" name="GrassyTile_01" tilewidth="32" tileheight="32" tilecount="4" columns="2">
  <image source="GrassyTile_01.png" width="64" height="64"/>
 </tileset>
 <tileset firstgid="5" name="BlackTile_01" tilewidth="32" tileheight="32" tilecount="1" columns="1">
  <image source="BlackTile_01.jpg" width="32" height="32"/>
 </tileset>

Regarding the "tileset" elements, there can be X amountof them, but they are not contained in an XmlArray, rather they just follow one-another.

I am looking for a method to use the XMLSerializer to Deserlialize these elements as an array, but I cannot find the correct way of doing this.

This is my code:

 [XmlRoot("map")]
        public class XMLMAP
        {
            [XmlAttribute("version")]
            public string Version;
            [XmlAttribute("orientation")]
            public string Orientation;
            [XmlAttribute("renderorder")]
            public string Renderorder;
            [XmlAttribute("width")]
            public int Width;
            [XmlAttribute("height")]
            public int Height;
            [XmlAttribute("tilewidth")]
            public int Tilewidth;
            [XmlAttribute("tileheight")]
            public int TileHeight;
            [XmlAttribute("nextobjectid")]
            public int NextObjectID;
            [XmlArray]
            public XMLMAP_TILESET[] TileSets;
            [XmlRoot("tileset")]
            public class XMLMAP_TILESET
            {
                [XmlAttribute("firstgid")]
                public string FirstGID;
                //No need for rest of code
            }
        }

Anyone know if this is possible or will I have to resort to an XMLReader?

"map" is not the root at all

Try redefining your XMLMAP class as:

[XmlRoot("map")]
public class XMLMAP
{
    [XmlAttribute("version")]
    public string Version;
    [XmlAttribute("orientation")]
    public string Orientation;
    [XmlAttribute("renderorder")]
    public string Renderorder;
    [XmlAttribute("width")]
    public int Width;
    [XmlAttribute("height")]
    public int Height;
    [XmlAttribute("tilewidth")]
    public int Tilewidth;
    [XmlAttribute("tileheight")]
    public int TileHeight;
    [XmlAttribute("nextobjectid")]
    public int NextObjectID;

    [XmlElement("tileset")]
    public List<TileSet> TileSets;
}

[XmlRoot("tileset")]
public class TileSet
{
    [XmlAttribute("firstgid")]
    public string FirstGID;
}

Where XMLMAP contains a List<TileSet>, and TileSet is then defined as a seperate class containing all the required attributes etc.

I can now deserialise with

var serializer = new XmlSerializer(typeof(XMLMAP));

var reader = new StreamReader(path);
var map = (XMLMAP)serializer.Deserialize(reader);
reader.Close();

And can see that map contains a list of 2 TileSets

Note that I could only do this after adding a closing </map> tag to the end of your supplied xml.

Hope that helps

Shorting after asking the question I ended up figuring this out, but thank you so much for being someone that actually answers the question!

@XBLToothPik no worries, I've struggled with this before so I know it can be confusing before understanding it properly
