问题
I'm using the Google OAuth API Client Library for .NET The code I'm using is based on: Oauth 2.0
The authorisation is working fine.
I'd like to pass a couple of parameters into the authorisation process. It seems the state querystring is used for this process, but I can't see how to achieve this with the C# client library.
