Reading XML in C#

This seems like rather too much nesting:

using (XmlReader reader = XmlReader.Create(filename))
{
    while (reader.Read())
    {
        if (reader.IsStartElement())
        {
            switch (reader.Name)
            {
                case "Width":
                    map.Width = ParseXMLValue(reader);
                    break;
                case "Height":
                    map.Height = ParseXMLValue(reader);
                    break;
                case "TileSize":
                    map.TileSize = ParseXMLValue(reader);
                    break;
                case "Layers":
                    map.LayerCount = ParseXMLValue(reader);
                    break;
                case "Layout":
                    ParseLayout(reader);
                    break;
                case "Layer":
                    currentLayerIndex = ParseLayer(reader);
                    break;
                case "CollisionLayer":
                    currentLayerIndex = ParseCollisionLayer();
                    break;
                case "Row":
                    ParseRow(reader);
                    break;
            }
        }
    }
}

This is ParseXMLValue(reader):

private int ParseXMLValue(XmlReader reader)
{
    reader.Read();

    return int.Parse(reader.Value);
}

I'm new to reading XML in C#. Surely there is a better way?

Yes, much. XDocument is the easier way. Though it does not perform as well if your documents are of significant size or performance is absolutely imperative:
http://www.nearinfinity.com/blogs/joe_ferner/performance_linq_to_sql_vs.html

It works like:

XDocument someXmlDoc = XDocument.Create(fileName);
IEnumerable widthElements = someXmlDoc.Descendants("Width");
int[] widthValues = widthElements.Select(xelement => int.Parse(xelement.Value)).ToArray();

Though I don't understand the logic in your snippet as you're setting elements of the same member repeatedly, so I'm not going to reserve giving a more eleborate use case that might match your functionality better, though I would suggest reading the msdn articles for IEnumerable.Select() and IEnumerable.Where() to get an idea how to use it for your particular purposes.
