Question

School gave me an XML document, and I have to display the information on a screen. As far as I know, Xml Deserialization would be the easiest/nicest solution.

I have this so far:

public static List<Project> ProjectListDeserialize(string path)
{
    XmlSerializer serializer = new XmlSerializer(typeof(List<Project>));
    Stream filestream = new FileStream(path, FileMode.Open);
    return (List<Project>)serializer.Deserialize(filestream);
}

public static Projects ProjectsDeserialize(string path)
{
    XmlSerializer serializer = new XmlSerializer(typeof(Projects));
    Stream filestream = new FileStream(path, FileMode.Open);
    return (Projects)serializer.Deserialize(filestream);
}

And this is how the XML document looks like:

<?xml version="1.0" encoding="utf-16" ?>    
<Projects xmlns="http://www.pulse.nl/DynamicsAX/2009/DataSets" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <Project ID ="1000.0001" CustomerID="1000">
        <Name>Project data key performance indicators</Name>
        <Status>WorkInProgress</Status>
        <StartDate>2011-01-01</StartDate>
        <ExpectedCompletionDate>2011-08-01</ExpectedCompletionDate>
        <CompletionDate xsi:nil="true" />
    </Project>
    <Project ID ="1000.0008" CustomerID="1000" ParentID="1000.0001">
        <Name>Implementation</Name>
        <Status>WaitListed</Status>
        <StartDate>2011-06-01</StartDate>
        <ExpectedCompletionDate>2011-08-01</ExpectedCompletionDate>
        <CompletionDate xsi:nil="true" />
    </Project>
</Projects>

Both methods are throwing the same exception:

<Projects xmlns='http://www.pulse.nl/DynamicsAX/2009/DataSets was not expected

How can I correctly deserialize the above xml? Any samples would be helpful!

Try specifying the default namespace for the XML document in the constructor of the XmlSerializer:

var serializer = new XmlSerializer(typeof(Projects), "http://www.pulse.nl/DynamicsAX/2009/DataSets");
