Question

我有奇怪的问题我想从Oracle（在线Db）获取记录并插入和更新到脱机的MySQL数据库数据库，如果故障转移MYSQL数据库启动功能。我必须将主要记录从Oracle更新到MySql，这样如果离线数据库在游戏中启动，它就会包含所有相关的同步数据。

我已经用BackgroundWorker类编写了代码，以便我可以将它保存在一个单独的线程中以下是代码，请查看

代码

namespace HospitalSystem
{
    /// <summary>
    /// Interaction logic for HospitalSync.xaml
    /// </summary>
    public partial class HospitalSync : Window
    {
       public BackgroundWorker Worker;
       public int TotalRecords;

        public HospitalSync()
        {
            InitializeComponent();
        }

        public int CalculatePercentage(int Current)
        {
            int Percentage = (int) (Current / TotalRecords) * 100;
            return Percentage;
        }

        public void SyncDataFromKPT(object sender, DoWorkEventArgs e)
        {
            MedEntities Db = new MedEntities();

            using (OracleConnection connection = new OracleConnection(Db.Database.Connection.ConnectionString))
            {
                DataTable RecordsToUpdateTable = new DataTable();
                string SqlCommand = "SELECT * FROM medsec.vu_registration_modify";
                using (OracleCommand cmd = new OracleCommand(SqlCommand, connection))
                {
                    OracleDataAdapter adapter = new OracleDataAdapter(SqlCommand, connection);
                    adapter.SelectCommand.CommandType = CommandType.Text;
                    adapter.Fill(RecordsToUpdateTable);
                    if (RecordsToUpdateTable.Rows.Count > 0)
                    {
                        for (int j = 0; j <= RecordsToUpdateTable.Rows.Count; j++)
                        {
                            RecCountTotal.Content = j + 1;
                            CalculatePercentage(j);
                        }

                    }

                }

            }

        }

        public void ProcessCompleted(object sender, ProgressChangedEventArgs e)
        {
            UpdateBar.Value = e.ProgressPercentage;
        }

        public void InitializeWorker()
        {
            Worker = new BackgroundWorker();
            Worker.WorkerReportsProgress = true;
            Worker.DoWork += new DoWorkEventHandler(SyncDataFromKPT);
            Worker.ProgressChanged += new ProgressChangedEventHandler(ProcessCompleted);
            Worker.RunWorkerAsync(Worker);  
        }   

        private void Button_Click_1(object sender, RoutedEventArgs e)
        {
            InitializeWorker();   
        }
    }
}

此时MedEntities Db = new MedEntities();在使用块之后进入文件，即使我放置断点也不会执行代码。

请指导我如何制作代码功能

在@Markus的帮助下解决了这个问题。谢谢

这是我使用32位客户端库并在64位上进行调试的平台问题。

后台工作程序未使用Oracle Connection
