如何将父表单设置为在C＃中从类打开的表单？

Question

我有一个父表单protected override void OnActivityResult(int iRequestCode, Android.App.Result oResultCode, Intent oIntent) { base.OnActivityResult (iRequestCode, oResultCode, oIntent); iValue = oIntent.Extras.GetInt("MYVALUE", -1); //=> 1234567890 } ，它会调用一个类AddEmployee，而类会打开另一个（子）表单Worker。我想将InformationFetching设置为AddEmployee的父格式，但我收到了跨线程错误。

InformationFetching

有人可以建议我在这里缺少什么吗？

根据评论，我建议这样：

private void brnContinue_Click(object sender, EventArgs e)
{
  Worker workerObject = new Worker(this);
  Thread thrd = new Thread(() =>
  {
    Invoke(new MethodInvoker(delegate
    {
      addNewAccount();  // Do something heavy for 30s
      workerObject.DoWork();
    }));
  });
  thrd.Start();
}

private void addNewAccount()
{
  validatorClass objClass = new validatorClass();
  bool isSuccess = false;
  isSuccess = objClass.verifyDetails(parameters);
}
