我正在尝试将 LinkedIn 集成到我的应用程序中，响应表中的值被覆盖

我有 3 张桌子

客户表（在 LinkedIn 中发布他们的详细信息的人将存储在此表中）

Customer_Id   Name    Cust_date   User_id   Community

Efthok        xxxx    04-Mar-13   Efthok    LinkedIn
df343n        yyyy    27-Jun-13   df343n    LinkedIn
4retee        zzzz    01-Jul-13   4retee    LinkedIn

Post Table(posts会存放在这里)Customer_Id是Customer表的外键

Customer_Id   Post_Id   Posts                   PostDate      Community

响应表（谁给帖子发表评论）//这里的值在我的代码中被覆盖 Response_Id Customer_Id Post_Id Response ResponseDate Community

我已经写了这段代码

获取 List<> 中的所有评论

  public void commentM()
    {
        XmlDocument d = new XmlDocument();
        d.LoadXml(content);

        XmlNodeList comments = d.SelectNodes("//comments/comment");
        foreach (XmlNode xncomment in comments)
        {
            commentId = xncomment["id"].InnerText;
            memComments = xncomment["text"].InnerText;
            string timeStamp = xncomment["creation-timestamp"].InnerText;
            double cmtTimeStamp1 = Convert.ToDouble(timeStamp);
            DateTime comment_timestamp1 = new DateTime(1970, 1, 1, 0, 0, 0, 0).AddSeconds(Math.Round(cmtTimeStamp1 / 1000d)).ToLocalTime();
            comment_timestamp = comment_timestamp1.ToString("dd-MMM-yy");

            commentData = new CommentData { CommentId = commentId, Comments = memComments, CommentTimeStamp = comment_timestamp };
            listComment.Add(commentData);
            commentM1();
        }
    }

 public void commentM1()
    {
        for (int i = 0; i < listCustomer.Count; i++)
        {
            var grt = listCustomer[i];
            id = grt.UserId;

            for (int k = 0; k < listPost.Count; k++)
            {
                string post_id1 = listPost[k].PostId;

                for (int j = 0; j < listComment.Count; j++)
                {
                    comId = listComment[j].CommentId;
                    comments1 = listComment[j].Comments;
                    commentTime = listComment[j].CommentTimeStamp;

                    DbConnection.Open();
                    DbCommand = new OleDbCommand("select count(response_id) from mw_response where response_id = '" + comId + "'", DbConnection);
                    OleDbDataReader DbReader = DbCommand.ExecuteReader();

                    while (DbReader.Read())
                    {
                        count = DbReader[0].ToString();
                        cnt = Convert.ToInt32(count);

                        if ((cnt == 0) && (memComments != ""))
                        {
                            DbCommand = new OleDbCommand("insert into mw_response(post_id,response,response_id, resp_date,community) values('" + post_id1 + "','" + comments1 + "','" + comId + "','" + commentTime + "','LinkedIn')", DbConnection);
                            DbCommand.ExecuteNonQuery();

                            //update productid and customerid
                            DbCommand = new OleDbCommand("update mw_response set prod_id = (select prod_id from mw_post where post_id='" + post_id1 + "'),customer_id = (select customer_id from mw_customer where customer_id = '" + id + "') where response_id = '" + comId + "'", DbConnection);
                            DbCommand.ExecuteNonQuery();

                                                        }
                    }
                    DbReader.Close();
                    DbConnection.Close();
                }
            }
        }
    }

我在 List<> 中为 Customer、Response 和 Post 值收集数据，然后在 CommentM1() 方法中循环这些值。

我想正确获得响应（帖子的评论）。

如果有人对这篇文章发表评论“我们正在提供贷款”，则来自（发布表）的 Post_id 和 customer_id 应该存储到响应表中。

有任何想法吗？提前致谢。

       for (int k = 0; k < listPost.Count; k++)
        {
            string post_id1 = listPost[k].PostId;

            for (int j = 0; j < listComment.Count; j++)
            {
                comId = listComment[j].CommentId;
                comments1 = listComment[j].Comments;
                commentTime = listComment[j].CommentTimeStamp;

                DbConnection.Open();
                DbCommand = new OleDbCommand("select count(response_id) from       mw_response where response_id = '" + comId + "'", DbConnection);
                OleDbDataReader DbReader = DbCommand.ExecuteReader();

                while (DbReader.Read())
                {
                    count = DbReader[0].ToString();
                    cnt = Convert.ToInt32(count);

                    if ((cnt == 0) && (memComments != ""))
                    {
                        DbCommand = new OleDbCommand("insert into mw_response(post_id,response,response_id, resp_date,community) values('" + post_id1 + "','" + comments1 + "','" + comId + "','" + commentTime + "','LinkedIn')", DbConnection);
                        DbCommand.ExecuteNonQuery();

                        //update productid and customerid
                        DbCommand = new OleDbCommand("update mw_response set prod_id = (select prod_id from mw_post where post_id='" + post_id1 + "'),customer_id = (select customer_id from mw_customer where customer_id = '" + id + "') where response_id = '" + comId + "'", DbConnection);
                        DbCommand.ExecuteNonQuery();

                                                    }
                }
                DbReader.Close();
                DbConnection.Close();
            }
        }

这个特定的 for 循环存在问题。如果您看到此循环，则仅当针对每个客户添加每个评论时，它才会结束。理想情况下，您应该考虑前一个 for 循环的索引值并将其传递以从评论列表中过滤评论并将其插入 dB。此 for 循环将始终添加重复记录。请删除此 for 并根据先前的 for 循环索引值过滤注释。希望这会有所帮助
