Python to csharp conversion of OSM parsing

[david khan]

Hello, can anybody convert python code that read openstreetmap xml file from

http://github.com/rory/python-osm/blob/master/pyosm.py
i try to translate but with the lack of knowledge of python , never get it done. Even approximate conversion that will be greate.

If the whole file is too much , if someone can translate a couple of class from this file like class Node(object):
class Way(object):

that will be great as well, and i will carry on trying with these sample.

#! /usr/bin/python
import xml.sax
 
class Node(object):
    def __init__(self, id=None, lon=None, lat=None, tags=None):
        self.id = id
        self.lon, self.lat = lon, lat
        if tags:
            self.tags = tags
        else:
            self.tags = {}
 
    def __repr__(self):
        return "Node(id=%r, lon=%r, lat=%r, tags=%r)" % (self.id, self.lon, self.lat, self.tags)
 
class Way(object):
    def __init__(self, id, nodes=None, tags=None):
        self.id = id
        if nodes:
            self.nodes = nodes
        else:
            self.nodes = []
        if tags:
