here's how i'd it.

list<string> links = new list<string>(); list<string> names = new list<string>(); htmldocument doc = new htmldocument(); //load html doc.load(new webclient().openread("http://geo.craigslist.org/iso/us")); //get links in div id = 'list' have href-attribute htmlnodecollection linknodes = doc.documentnode.selectnodes("//div[@id='list']/a[@href]"); //or if have links saved somewhere //htmlnodecollection linknodes = doc.documentnode.selectnodes("//a[@href]"); if (linknodes != null) {   foreach (htmlnode link in linknodes)   {     links.add(link.getattributevalue("href", ""));     names.add(link.innertext);//get innertext don't html-tags   } } //write both lists file file.writealltext("urls.txt", string.join(environment.newline, links.toarray())); file.writealltext("cities.txt", string.join(environment.newline, names.toarray()));
