【英文标题】：Is there a way to "notify" when you hit the hourly limit?

【问题描述】：

我目前正在查看 TweetInvi 的文档，并查看了 RateLimit 类。 而且我一直在尝试实现它，我不知道这是对 Twitter 缺乏了解还是限制，但我似乎无法找到一种方法来发送 notification 在控制台消息方面说“嘿，你已经达到了每小时的限制，它将在 x 分钟内重置……”或类似的内容。

我正在查看此示例，您也可以在文档中找到该示例。

TweetinviEvents.QueryBeforeExecute += (sender, args) =>

    var queryRateLimits = RateLimit.GetQueryRateLimit(args.QueryURL);

    // Some methods are not RateLimited. Invoking such a method will result in the queryRateLimits to be null
    if (queryRateLimits != null)
    
        if (queryRateLimits.Remaining > 0)
        
            // We have enough resource to execute the query
            return;
        

        // Strategy #1 : Wait for RateLimits to be available
        Console.WriteLine("Waiting for RateLimits until : 0", queryRateLimits.ResetDateTime.ToLongTimeString());
        Thread.Sleep((int)queryRateLimits.ResetDateTimeInMilliseconds);

        // Strategy #2 : Use different credentials
        var alternateCredentials = TwitterCredentials.CreateCredentials("", "", "", "");
        var twitterQuery = args.TwitterQuery;
        twitterQuery.OAuthCredentials = alternateCredentials;

        // Strategy #3 : Cancel Query
        args.Cancel = true;

        // Strategy #4 : Implement yours!
    
;

当我尝试发送一条推文说“嘿，慢点，伙计，你已经达到极限，请稍等（剩下的时间） )"

如果这个包装器甚至可以做到的话。

【参考方案1】：

请参阅下面的示例，希望对您有所帮助。

public class TwitterManager

    private readonly ITwitterCredentials _credentials;
    private bool _isRateLimited;

    public TwitterManager()
    
        _credentials = Auth.SetUserCredentials("", "", "", "");
        TweetinviEvents.QueryBeforeExecute += (sender, args) =>
        
            var queryRateLimit = RateLimit.GetQueryRateLimit(args.QueryURL);
            if (queryRateLimit != null)
            
                if (queryRateLimit.Remaining > 0)
                     return;
                else
                    _isRateLimited = true;
            
        ;

    

    public void GetTweets() 
        UserTimelineParameters userTimelineParameters = new UserTimelineParameters();
        userTimelineParameters.MaximumNumberOfTweetsToRetrieve = 50;
        try
        
            var tweets = Auth.ExecuteOperationWithCredentials(_credentials, () =>
            
                return Timeline.GetUserTimeline("cnn", userTimelineParameters);
            );

            if (_isRateLimited)
            
                Console.WriteLine("Request rate limit has been exceeded. Please try again later.");
            
            else if (tweets != null) 
                foreach (var item in tweets)
                
                    Console.WriteLine(item.FullText);
                
            
            Console.ReadKey();
        
        catch (WebException wex)
        
            var statusCode = -1;
            if (statusCode == TweetinviConsts.STATUS_CODE_TOO_MANY_REQUEST)
            
                // The RateLimit is exhausted. Perform your code to manage it!
