Here is the code that use oauth authentication 1.0.

Login with twitter using oauth authentication in asp.net and get access token, screen name and userid.

    OAuthHelper oauthhelper = new OAuthHelper();
    string requestToken = oauthhelper.GetRequestToken();

     if (string.IsNullOrEmpty(oauthhelper.oauth_error))
         Response.Redirect(oauthhelper.GetAuthorizeUrl(requestToken));
     else
          Response.Write(oauthhelper.oauth_error);

Return Url.

    if (Request.QueryString["oauth_token"] != null && Request.QueryString["oauth_verifier"]!=null)
    {
        string oauth_token = Request.QueryString["oauth_token"];
        string oauth_verifier = Request.QueryString["oauth_verifier"];

        OAuthHelper oauthhelper = new OAuthHelper();
        oauthhelper.GetUserTwAccessToken(oauth_token, oauth_verifier);

        if (string.IsNullOrEmpty(oauthhelper.oauth_error))
        {
            Session["twtoken"] = oauthhelper.oauth_access_token;
            Session["twsecret"] = oauthhelper.oauth_access_token_secret;
            Session["twuserid"] = oauthhelper.user_id;
            Session["twname"] = oauthhelper.screen_name;


            Response.Write("<b>AccessToken=</b>" + oauthhelper.oauth_access_token);
            Response.Write("<br /><b>Access Secret=</b>" + oauthhelper.oauth_access_token_secret);
            Response.Write("<br /><b>Screen Name=</b>" + oauthhelper.screen_name);
            Response.Write("<br /><b>Twitter User ID=</b>" + oauthhelper.user_id);
        }
        else
            Response.Write(oauthhelper.oauth_error);
    }

The verify_credentials API request will return information about the currently logged in user.

Also, Twitter's response to an OAuth access token request (i.e. the last part of the OAuth login procedure) responds with the user's screen name and Twitter user ID alongside the usual oauth token and secret.

Using Twitterizer library, here is a code snippet.

OAuthTokenResponse reqToken = OAuthUtility.GetAccessToken(ConsumerKey, ConsumerSecret, requestToken);

long UserID = reqToken.UserId;

string ScreenName = reqToken.ScreenName;

I've posted a sample code on my blog. http://www.fairnet.com/post/2010/09/05/Twitter-authentication-using-OAuth.aspx
