C# Webbrowser/IE 状态栏多次显示 "Done"，完成的真正含义是什么？

Question

C# webbrowser 中的 StatusTextChanged 事件显示多次完成，准确地说是 31 次，我看到几乎与 [=21= 中 x 的总和一样多].

我怎么知道什么时候真正完成了？或者，如果这不可能，我怎么知道特定元素何时呈现。

网上还有其他类似的问题，但只有一半的 hackey 结果。

谢谢@Golda，

您链接的 exact 答案无效，因为加载不是异步的，如果您添加周期性暂停，网络浏览器将不会继续加载。该线程上标记为答案的回复不是我要求的，但是结合这两个答案让我得到了我想要的东西，每隔 n 秒检查是否呈现具有特定属性的特定标记的代码。

  private void button1_Click(object sender, EventArgs e)
        {
            Navigate n = new Navigate();
            n.Done += delegate
            {
                MessageBox.Show("");
            };
    //wb is the webbrowser, nav is the url
            n.Wait(wb, nav, 1);

        }

        public class Navigate
        {
            public delegate void NavigateDoneEvent();
            public event NavigateDoneEvent Done;

            private Timer wait;
            HtmlElement e2 = null;

            public void Wait(WebBrowser Browser, string Url, double Seconds)
            {
                Browser.Navigate(Url);

                wait = new Timer();
                wait.Interval = Convert.ToInt32(Seconds * 1000);

                wait.Tick += (s, args) =>
                {
                    if (Form1.wb.Document != null)
                    {
                        HtmlElementCollection c1 = Form1.wb.Document.GetElementsByTagName("element tag type");

                        foreach (HtmlElement e3 in c1)
                        {
                            if (e3.GetAttribute("className") == "class name")
                            {
                                if (e3.InnerText.Contains("something"))
                                {
                                    e2 = e3;
                                    wait.Enabled = false;
                                    MessageBox.Show(e2.InnerText);
                                    Done();
                                }
                            }
                        }
                    }
                };

                wait.Enabled = true;
            }
        }
