How to get text after # character when receiving request via HttpListener?

Question

.NET

I'm sending an authorization request through a third party library to dropbox. Upon clicking a button in the browser, dropbox requests a redirect_uri that my app is listening on. The format is as follows

[REDIRECT_URI]#access_token=ABCDEFG&token_type=bearer&uid=12345&state=[STATE]

I'm using the HttpListener class, but after receiving a request, the httpListener.Request.Url property contains the address before the hash.
I tried it, it always does this - shows the address up to the hash mark and up to the question mark too, if it is used. Question: how to deal with it?

Answer 1

char[] separators = { '=', '&' };
string[] responseContent = responseString.Split(separators);
string accessToken = responseContent[1];
int userId = Int32.Parse(responseContent[5]);
MessageDialog dialogSuccess = new MessageDialog("access_token = "+accessToken+ "\nuser_id = "+userId);
dialogSuccess.ShowAsync();
