Как добавить / вставить многопоточность при запуске или выполнении в WinForm (см. Мой код)

Question

Когда я запускаю свои коды и нажимаю кнопку "Выполнить", он зависает при запуске (особенно, когда я запускаю больше файлов), и я больше не могу щелкнуть мою основную форму, ему нужно сначала завершить выполнение, прежде чем взаимодействовать с моей основной формой. Я исследовал, что мне нужно многопоточность. Как я вставлю код многопоточности или фона, чтобы я мог по-прежнему взаимодействовать с моей формой.?

Здесь ниже кнопка выполнения, где, когда я щелкаю по ней, запускается выполнение моих скриптов и замораживается моя форма, когда она не закончена.

Answer 2

Перетащите BackgroundWorker в форму, добавьте следующий код в событие Execute_Click.

  try
  {
    BackgroundWorker1.RunWorkerAsync() ;
  }   
  catch
  {
    BackgroundWorker1.WorkerSupportsCancellation = True
    BackgroundWorker1.CancelAsync()
  }

Добавьте событие Do_Work своему фоновому работнику.

  private void BackgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
  {
        //You need to add CheckForIllegalCrossThreadCalls to allow
        BackgroundWorker access the objects you used in the form.

        Label.CheckForIllegalCrossThreadCalls = false;
        ProgressBar.CheckForIllegalCrossThreadCalls = false;
        RichTextBox.CheckForIllegalCrossThreadCalls = false;
        TextBox.CheckForIllegalCrossThreadCalls = false;

        try
    {                
        //Execution Pane
        timer1.Start();
        progressBar1.Maximum = checkedListBox1.CheckedItems.Count;

        richTextBox2.Text = "";
        string file_name = "\\test1.sql";
        file_name = textBox1.Text + file_name;
        {                 
            string line;
            line = null;

            foreach (Object item in checkedListBox1.CheckedItems)
            {

                string sql_name = "\\test1.sql";
                sql_name = textBox1.Text + sql_name;
                StreamWriter SaveFile = new StreamWriter(sql_name);
                SaveFile.WriteLine(":r \"" + textBox1.Text + "\\" + item + "\"");
                SaveFile.Close();

                line += item + "\n";

                StreamReader sql = new StreamReader(sql_name);
                //richTextBox1.Text = sr.ReadToEnd();
                sql.Close();
                sql.Dispose();

                //Create a batchfile for execution of consolidated script 
                string execute = "\\Script_Runner.bat";

                SaveFile2.WriteLine("sqlcmd -S localhost -E -i " + textBox1.Text + "\\" + "test1.sql");
                //Environment.NewLine + "pause");
                SaveFile2.Close();

                //running the batchfile
                string ScriptRun = "\\Script_Runner.bat";
                ScriptRun = textBox1.Text + ScriptRun;
                Process.Start(ScriptRun);

                progressBar1.PerformStep();
                this.Refresh();

            }

            richTextBox2.Text = line;
            richTextBox2.Text += "\nData Patch Completed.";

            transfer = label3.Text;
            NotificationForm NF = new NotificationForm();
            NF.Show();

        }

    }
    catch (Exception ex)
    {
        string filePath = @"C:\Error.txt";
        filePath = textBox1.Text + filePath;

        using (StreamWriter writer = new StreamWriter(filePath, false))
        {
            writer.WriteLine("Message :" + ex.Message + Environment.NewLine + "StackTrace :" + ex.StackTrace +
               "" + Environment.NewLine + "Date :" + DateTime.Now.ToString());
            writer.WriteLine(Environment.NewLine + "-----------------------------------------------------------------------------" + Environment.NewLine);
        }
    }
