一周前，我遇到了从 TweetSharp 库获取请求令牌的问题，每次它抛出 null 异常。以前它有效，凭据有效。来自https://github.com/shugonta/tweetsharp 的测试出现同样的问题 看起来 TweetSharp 代理又出现了一些问题。

var service = new TwitterService(_consumerKey, _consumerSecret);
var requestToken = service.GetRequestToken();

System.ArgumentNullException : Value cannot be null.
Parameter name: query
