我正在尝试将社交媒体与 siebel

我收到一个错误

“索引超出了数组的范围”

我无法修复错误

代码：

    public void Call_Tweet_Update()
    {
        var service = new TwitterService(Consumer_Key, Consumer_Secret);
        service.AuthenticateWith(Access_Token, AccessToken_Secret);

        var tweets = service.ListTweetsOnHomeTimeline(new ListTweetsOnHomeTimelineOptions { Count = 100 });
        string[] twt_id = new string[100];
        long id = 0;
        int i = 0;
        int increment = 0;
        string twtid;
        string screenname;

        foreach (var tweet in tweets)
        {
            if (tweet.InReplyToStatusId.ToString() != "")
            {
                if ((tweet.User.ScreenName == "IIPL_LTD") || (tweet.Text.StartsWith("@IIPL_LTD")))
                {
                    string replyid = tweet.InReplyToStatusId.ToString();

                    while (replyid != "")
                    {
                        if (i == 0)
                        {
                            twt_id[i] = tweet.Id.ToString();
                        }
                        id = Convert.ToInt64(replyid);
                        twtid = Convert.ToInt64(tweet.Id).ToString();
                        i = i + 1;
                        twt_id[i] = twtid;
                        increment = increment + 1;//Here I get an error
                    }

                                    {
                                        createComment(twt_id[i]);
                                    }
                                }
                                DbReader0.Close();
                            }
                            DbReader.Close();
                            increment = increment - 1;
                            i = i + 1;
                        }
                        i = 0;
                    }
                }
            }
        }
        DbConnection.Close();
    }

这是程序被终止的地方 Index 超出了数组的范围

 if(i == 0)
 {
    twt_id[i] = tweet.Id.ToString();
 }
 id = Convert.ToInt64(replyid);
 twtid = Convert.ToInt64(tweet.Id).ToString();
 i = i + 1;
 twt_id[i] = twtid;
 increment = increment + 1;

有任何想法吗？提前致谢。

如果replyid不是空字符串，您的代码将进入 while 循环，并且永远不会退出它。当i增加到 100 时，代码然后尝试访问twt_id[100]导致此异常的访问。有人会认为这意味着您打算replyid在循环体结束之前进行修改，但还没有解决。

当然，单步执行您的代码 - 或检查i异常点的值并推断原因- 会揭示这个问题。
