Hi,
You have 2 problems that I can see here. The first one is that you try to access a stream from a webpage.
I think you should have this done on your server as webservice because it is an ongoing process.
Second you need to specify credentials when you want to use the Twitter API.
To get such credentials you need to go on https://apps.twitter.com/.
Then in Tweetinvi you need to specify the credentials as the first operation you do with Tweetinvi in your code.
I hope this makes some sense.

TwitterCredentials.SetCredentials("Access_Token", "Access_Token_Secret", "Consumer_Key", "Consumer_Secret");
