MySqlClient EndOfStreamException：尝试读取流结束时发生致命错误

Question

我开发了一个Windows服务来从csv读取数据并将它们写回数据库。

执行程序后，它将正常工作，直到几分钟后到达下面的行时触发错误

cmd.ExecuteNonQuery（）;

错误的屏幕截图：

数据已写入数据库，直到弹出此错误。

触发错误最多需要2-3分钟。

我将包含此问题的相关代码块。

   public void Insert()
        {
                if (this.OpenConnection() == true)
                {
                      using(var reader = new StreamReader(@"C:UsersAdminsourceBargstedt.csv"))
                    {
                        List<string> listA = new List<string>();

                        while (!reader.EndOfStream)
                        {
                            var line = reader.ReadLine();
                            var values = line.Split(',');
                            string querynew = "INSERT INTO new_jobs"
                                      + "(job_reference,status,code,no1,no2,no3,dimension,date_assigned,root,variable,number,stable,constant)" 
                                      + "VALUES (?jobNo, ?strClientName, ?strClientReference, ?strJobCategory, ?datCommisioned, ?datPromisedDelivery, ?division, ?date_assigned, ?root, ?variable, ?number, ?stable, ?constant)";

                                mysqlCommand cmd = connection.CreateCommand();
                        cmd.CommandText= querynew;
                                cmd.Parameters.Add("?jobNo", MySqlDbType.VarChar).Value = (values[0]);
                                cmd.Parameters.Add("?strClientName", MySqlDbType.VarChar).Value =(values[1]);
                                cmd.Parameters.Add("?strClientReference", MySqlDbType.VarChar).Value = values[2];
                                cmd.Parameters.Add("?strJobCategory", MySqlDbType.VarChar).Value = values[3];
                                cmd.Parameters.Add("?datCommisioned", MySqlDbType.VarChar).Value = values[4];
                                cmd.Parameters.Add("?datPromisedDelivery", MySqlDbType.VarChar).Value = values[5];
                                cmd.Parameters.Add("?division", MySqlDbType.VarChar).Value = values[7];
                        cmd.Parameters.Add("?date_assigned", MySqlDbType.VarChar).Value = values[9];
                        cmd.Parameters.Add("?root", MySqlDbType.VarChar).Value = values[10];
                        cmd.Parameters.Add("?variable", MySqlDbType.VarChar).Value = values[11];
                        cmd.Parameters.Add("?number", MySqlDbType.VarChar).Value = values[12];
                        cmd.Parameters.Add("?stable", MySqlDbType.VarChar).Value = values[13];
                        cmd.Parameters.Add("?constant", MySqlDbType.VarChar).Value = values[14];





                        cmd.ExecuteNonQuery(); **error line
                        }
                    }
                    this.CloseConnection();
                }



        }

为了更清楚，我还将包含csv文件和数据库结构的屏幕截图。

在csv的行中间有一些空格，这就是我在源代码中跳过第6行和第8行的原因。
