I use the Facebook C# SDK as well. You'll need the following permissions:

manage_pages  
read_stream  
publish_stream

HTTP Get to "me/accounts" and get the .data object off of the returned value. This will be a list of the following:

  var list = ApiGet("me/accounts").data;
  foreach (dynamic acc in list)
  {              
    var name = (string)acc.name;
    var accessToken = (string)acc.access_token;
    var category = (string)acc.category;
    var pageId = (string)acc.id;
  }

As you can see, each one of the pages have their own unique access token.
