版本一:query.v1 C# OAuth2 收到 401 未经授权的错误，但 rest-1.oauth.v1/Data

我能够使用 OAuth2 和这个进行查询：

/rest-1.oauth.v1/Data/Story?sel=Name,Number&Accept=text/json

但是，我无法让 OAuth2 和新查询 1.v1 对抗 Sumnmer2013 版本一。 我收到 （401） 使用两个不同的 URL 不支持未经授权和指定的方法。

下面是包含工作/rest-1.oauth.v1 和非工作查询 1.v1 和非工作 query.legacy.v1 的代码。 滚动到代码底部以查看程序主（代码的起点）请告知我在这里缺少什么。
