c# xmldocument load access violation

Question

I am trying to load a xml file from c# in the code behind of a windows forms application. This is the code I use:

        XmlDocument xdoc = new XmlDocument();
        xdoc.Load("file.xml");

        foreach (XmlNode obj in xdoc.SelectNodes("/enabledobjects/object/*"))
        {
            RadListDataItem item = new RadListDataItem();

            item.Text = obj["objectname"].InnerText;
            item.Value = obj["value"].InnerText;

            DropDownList.Items.Add(item);
        }

When i run debug the program, the I gent no errors. The program starts like it should for a few seconds. Then it carashes and finishes the debugging. Visual Studio shows following message:

The program '[6728] Daten Archivar.vshost.exe: Managed (v4.0.30319)' has exited with code -1073741819 (0xc0000005) 'Access violation'.

I have full administrator privileges. The file is saved in the same folther the exe is saved with full access for everyone. I have no Idea why I cant access it.

The xml file looks like this:

<?xml version="1.0" encoding="utf-8" ?>
<enabledobjects>
    <object>
      <objectname>John</objectname>
      <value>Carter</value>
    </object>
</enabledobjects>

Ok, this is really a bad mistake. The error occures because the xpath was wrong:

foreach (XmlNode obj in xdoc.SelectNodes("/enabledobjects/object/*"))
    {

     RadListDataItem item = new RadListDataItem();
     item.Text = obj["objectname"].InnerText;

by looping like this, we try with the obj["objectname"].InnerText to access the "objectname" child of <objectname>John</objectname>.

The solution to this problems is easy:

foreach (XmlNode obj in xdoc.SelectNodes("/enabledobjects/object"))
    {

     RadListDataItem item = new RadListDataItem();
     item.Text = obj["objectname"].InnerText;

by removing /* we define the <object> as xmlNode object.

So the access violation was created because the child, we wanted to read out the innerText, never existed. Hope this helps someone sometime.
