找不到OAuth2Parameters

Question

我正在尝试使用Google2.0来授权google docs API，根据OAuth在https://developers.google.com/google-apps/documents-list/#authorizing_requests_with_oauth_20给出的例子，他们使用的是下面这段代码：

// OAuth2Parameters holds all the parameters related to OAuth 2.0.
      OAuth2Parameters parameters = new OAuth2Parameters();

      // Set your OAuth 2.0 Client Id (which you can register at
      // https://code.google.com/apis/console).
      parameters.ClientId = CLIENT_ID;

      // Set your OAuth 2.0 Client Secret, which can be obtained at
      // https://code.google.com/apis/console.
      parameters.ClientSecret = CLIENT_SECRET;

      // Set your Redirect URI, which can be registered at
      // https://code.google.com/apis/console.
      parameters.RedirectUri = REDIRECT_URI;

      ////////////////////////////////////////////////////////////////////////////
      // STEP 3: Get the Authorization URL
      ////////////////////////////////////////////////////////////////////////////

      // Set the scope for this particular service.
      parameters.Scope = SCOPE;

      // Get the authorization url.  The user of your application must visit
      // this url in order to authorize with Google.  If you are building a
      // browser-based application, you can redirect the user to the authorization
      // url.
      string authorizationUrl = OAuthUtil.CreateOAuth2AuthorizationUrl(parameters);

问题是，当我尝试使用这段代码时，它告诉我找不到OAuth2Parameters，我同时使用了Google.GData.Client；和Google.GData.Documents；

在这里做什么？？

要使用OAuth2Parameters类，您必须签出该库的源代码并自行构建：

http://code.google.com/p/google-gdata/source/checkout

该类将包含在即将发布的2.0版本的库中。
