Dapper批量删除如何汇报进度

Question

我正在使用 Dapper Plus 使用来自另一个 table 的查询进行批量插入，我的问题是如何报告进度。如您所见，我正在使用后台工作进程运行我的代码工作正常，但是由于批量删除方法没有 reportprogress 事件，我将如何处理它。

public StockDeativationForm()
{
        InitializeComponent();
        this._backgroundWorker.DoWork += new DoWorkEventHandler(this.BackgroundWorkerDoWork);
        this._backgroundWorker.ProgressChanged += new ProgressChangedEventHandler(this.BackgroundWorkerProgressChanged);
        this._backgroundWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(this.BackgroundWorkerRunWorkerCompleted);

 }

private void BackgroundWorkerDoWork(object sender, DoWorkEventArgs e)
{
     ProcessStockItems();
}

private void BackgroundWorkerProgressChanged(object sender, ProgressChangedEventArgs e)
{
        this.progressBar2.Value = e.ProgressPercentage;

 }

private void BackgroundWorkerRunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
        this.CompleteProcess();
 }


private void CompleteProcess()
{
        MessageBox.Show("Stock items Deleted", "Stock Item Delete", MessageBoxButtons.OK, MessageBoxIcon.Asterisk);
        base.Close();
 }

public StockDeativationForm()
{
        InitializeComponent();
        this._backgroundWorker.DoWork += new DoWorkEventHandler(this.BackgroundWorkerDoWork);
        this._backgroundWorker.ProgressChanged += new ProgressChangedEventHandler(this.BackgroundWorkerProgressChanged);
        this._backgroundWorker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(this.BackgroundWorkerRunWorkerCompleted);

}

private void ProcessStockItems()
{
    string conStr = ConfigurationManager.AppSettings["DeleteStock"];
    using (var connection = new SqlConnection(conStr))
    {

      DialogResult _dialogResult = MessageBox.Show(null, "Are you sure you want to delete stock? This will delete all stock items", "Delete Stock", MessageBoxButtons.YesNo);
       if (_dialogResult == DialogResult.Yes)
       {

  connection.BulkDelete(connection.Query<StockItems>("Select ItemID FROM StockItem").ToList());
        }
     }
 }

使用这种bulkdelete方法如何报告进度

  connection.BulkDelete(connection.Query<StockItems>("Select ItemID FROM StockItem").ToList());

你是对的，

也许使用日志事件可行？

StringBuilder log = new StringBuilder();

connection.UseBulkOptions(options => options.Log = s => {
    if(s.Contains("...xyz...")) {
        log.AppendLine(s);
    }   
}).BulkDelete(connection.Query<StockItems>("Select ItemID FROM StockItem").ToList());

另一种解决方案是向我们的支持团队报告此请求并要求报告 Progress/Notify 事件。
