BackgroundWorker 未完全执行。C＃

是BackgroundWorker执行某个代码。完成后，它必须将变量写入label. 但它不会发生。然后我决定把代码拆成BackgroundWorker小块，执行完一段代码后，Console.WriteLine显示段数（ ），只有8个，前7个是条件检查，最后一个是输出。然后当我编译程序时，我在输出中看到：

1
2
3
4
5
6
7

它与什么有关？

启动worker的方法：

 private void Form1_Load(object sender, EventArgs e)
        {
            guna2GradientCircleButton2.PerformClick();
            RegistryChecker.RunWorkerAsync();
        }
