Facebook Upload Photo using c#

You can either create one album and upload to the album, otherwise you can upload to the default album of your app.
In order to publish a photo to a user’s album, you must have the publish_stream permission. With that granted, you can upload a photo by issuing an HTTP POST request with the photo content and an optional description to one these to Graph API connections:

• https://graph.facebook.com/USER_ID/photos - The photo will be published to an album created for your app. We automatically create an album for your app if it does not already exist. All photos uploaded this way will then be added to this same album.
  
• https://graph.facebook.com/ALBUM_ID/photos - The photo will be published to a specific, existing photo album, represented by the ALBUM_ID.
