Join on filtering OSM data

[bryanschoot]

At the moment Iam doing this in seperate functions but is it possible to do something simulair to te code below?

// Constants.TagStreet => "addr:street";
// Constants.TagPostalCode => "addr:postcode";
// Constants.TagHighway => "highway";
// Constants.TagName => "name";

 OsmHelper.Download(Constants.Url, Constants.File);

  using var fileStream = File.OpenRead(Constants.File);
  var source = new PBFOsmStreamSource(fileStream);
  var results = new List<Address>();

  foreach (var address in addresses)
  {
      var final = from osmAddresses in source
                  where osmAddresses.Type == OsmGeoType.Node
                      && osmAddresses.Tags != null
                      && osmAddresses.Tags.ContainsKey(Constants.TagStreet)
                      && osmAddresses.Tags.Contains(Constants.TagPostalCode, address.Zip.NormalizeZip())
                  join osmWays in source on osmAddresses equals osmWays
                  where
                      osmWays.Type == OsmGeoType.Way
                      && osmWays.Tags != null
                      && osmWays.Tags.Contains(Constants.TagName, osmAddresses.Tags[Constants.TagStreet])
                      && osmWays.Tags.ContainsKey(Constants.TagHighway)
                  select new Address
                  {
                      Street = osmAddresses.Tags[Constants.TagStreet],
                      Zip = osmAddresses.Tags[Constants.TagPostalCode],
                      GeoLocation = new GeoLocation
                      {
                          Longitude = ((Node)osmAddresses).Longitude,
                          Latitude = ((Node)osmAddresses).Latitude
                      },
                      Nodes = ((Way)osmWays).Nodes.ToList()
                  };

      results.AddRange(final);
  }
