Newbie:
I am writing code to read an xml file. I want two values from the document
so I want to save them as I am reading through the elements. I want to
reference them (using Console.WriteLine) after I complete the loop. When I
compile I get the "use of unassigned local variable".

What am I doing wrong?

stripped down code:
static void Main()
{
string Msg;

try
{
        // Open an XML file
        XmlTextReader reader = new XmlTextReader("...");

        while ( reader.Read() )
        {
                if (reader.NodeType == XmlNodeType.Whitespace)
                        continue;
                                        
                if (reader.NodeType != XmlNodeType.EndElement )
                {
                        Msg = reader.Value;
                }

                if (reader.HasAttributes)
                {
                        reader.MoveToFirstAttribute();
                }
          }
}
catch (Exception e)
{
        Console.WriteLine ("Exception: {0}", e.ToString());
}

Console.WriteLine(Msg);
}
