FormVariables.ToString Method 

Serializes all the name/value pairs into a string. The format of the string matches the HTTP protocol specification for transmitting form variables to a server. This can be handy for checking the form variables in your web page. Generally you won't be sending it to a server because HttpClient handles that for you.
