Question

I have a Silverlight application in which I am doing the following thing to load a XML file, and further to parse it.

I have set the Build Action to Embedded Resource, Copy to Output Directory.
The code that I am using is:

try
            {
                Xmlfile = XDocument.Load(Assembly.GetExecutingAssembly().GetManifestResourceStream("file.xml"));
            }
            catch(Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

Message that I receive as an exception:
Value cannot be null.
Parameter name: input

EDIT

I tried the following which works (in WPF), but gives problem in Silverlight:

Assembly.GetExecutingAssembly().GetManifestResourceStream(Assembly.GetExecutingAssembly().GetName().Name + ".file.xml")

Error:

'System.Reflection.Assembly.GetName()' is inaccessible due to its protection level

You will need to prepend the name of your assembly and its subfolders, like this:

string assemblyName = System.Reflection.Assembly.GetExecutingAssembly().GetName().Name;
XDocument.Load(assemblyName + ".subfolder.file.xml");

Sometimes it’s not clear exactly what the subfolder(s) should be. If that’s the case, just inspect the names directly using this:

string[] names = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceNames();
