Debugging Reading XML into class in C#

Question

I'm trying make a program to read a simple xml file into my class. I've been using this previous question as a guide: How to Deserialize XML document

The code runs fine with no exceptions, but for some reason, SCArray.ShortCut = null and count is 0. I'm having trouble debugging this because there are no exceptions.

Is there a way to catch this error (i.e., why it's not reading the xml correctly, or what part of my code is causing it to return null results from reading the xml)?

<?xml version="1.0"?>
<ShortCutsArray>
    <Shortcut>
        <Name>Item1</Name>
        <Path>http://www.example1.com</Path>
    </Shortcut>
    <Shortcut>
        <Name>Item2</Name>
        <Path>\\Server\example2\ex2.exe</Path>
    </Shortcut>
</ShortCutsArray>

The c# code:

class Program
{
    public static void Main(string[] args)
    {
        string shortcuts_file = @"\\server\ShortcutLocation.xml";
        ShortCutsArray SCArray = null;
        XmlSerializer serializer = new XmlSerializer(typeof(ShortCutsArray));
        StreamReader reader = new StreamReader(shortcuts_file);
        SCArray = (ShortCutsArray)serializer.Deserialize(reader);
        reader.Close();
    }
}
[Serializable()]
[System.Xml.Serialization.XmlRoot("ShortCutsArray")]
public class ShortCutsArray
{
    [XmlArray("ShortCutsArray")]
    [XmlArrayItem("ShotCut", typeof(ShortCut))]
    public ShortCut[] ShortCuts { get; set; }
}
[Serializable()]
public class ShortCut
{
    [System.Xml.Serialization.XmlElement("Name")]
    public string Name { get; set; }
    [System.Xml.Serialization.XmlElement("Path")]
    public string Path { get; set; }
}

Looks like a typo here: [XmlArrayItem("ShotCut", typeof(ShortCut))] should be [XmlArrayItem("ShortCut", typeof(ShortCut))] (ShotCut --> ShortCut) — David LaPorte

Mostly correct: ShotCut -> Shortcut (note the small c as well) — J. Steen

Typo: ShotCut -> Shortcut (note the lower case c - either making the ShortCut class Shortcut or change you xml to be ShortCut would be better)

You've got the root as ShortCutsArray and the XML array name as ShortCutsArray. You'd need the following xml for it to work:

<ShortCutsArray>
    <ShortCutsArray>
        <Shortcut>
            <Name>Item1</Name>
            <Path>http://www.example1.com</Path>
        </Shortcut>
        <Shortcut>
            <Name>Item2</Name>
            <Path>\\Server\example2\ex2.exe</Path>
        </Shortcut>
    </ShortCutsArray>
</ShortCutsArray>

I'm not sure its possible to debug this as there's nothing going wrong you've simply found no elements that match due to the above errors.
