I found the following code to create a tinyurl.com url:
http://tinyurl.com/api-create.php?url=http://myurl.com
This will automatically crea
You have to call that URL from your code, then read back the output from the server and process it.
Have a look at the System.Net.WebClient class, DownloadString (or better: DownloadStringAsync) seems to be what you want.
