Concatenation of variables is done at run time, so you either need to
make the strings constant or use properties to allow the concatenation to
occur at run time:

void main () {
     var a = new Test ();
  print (@"Extension: $(Test.ext)\n");
  print (@"Filename: $(a.filename)\n");
  print (@"Path: $(a.path)\n");
}

class Test {
  public const string ext = ".ext";
  private string _filename;
  public string filename {get {_filename = "test" + ext; return _filename;}}
  private string _path;
  public string path {get {_path = "/full/path/" + filename; return _path;}}
}
