在不同的线程运行与控制浏览器控件 [英] Run and control browser control in different thread

问题描述

我有一些subclassess我的主GUI类。有+ - 。3线程正在收集各种网络资源和API网关等数据。

I have my main gui class with some subclassess. There are +- 3 threads that are collecting data from various internet sources and API gateways etc.

现在，这些线程之一，我想运行一个WebBrowser控件，这样我就可以添加一些autobrowsing功能，我的计划。每个子线程应该能够打开自身一个网页浏览器的。所以，我创建了一个第二个C＃窗口形式，它仅包含控制网页浏览

Now, out of one of these threads, I want to run a webbrowser control, so I can add some autobrowsing functionality to my program. Each of the sub threads should be capable of opening a webbrowser on its own. So I created a second c# windows form, which contains only the webbrowsing control.

我已经使用ApartmentState.STA上WebBrowser控件这个新的线程设置。不过，该窗体2没有响应

I already use the ApartmentState.STA setting on this new thread for the webbrowser control. However, the form2 is unresponsive.

我试着打电话给Application.Run（）;从这个线程，这使得web浏览器/窗体2响应。但后来我的主线程停止运行。

I tried to call Application.Run(); from this thread, and this makes the webbrowser/form2 responsive. But then my main thread stops running.

所以，我在如何进行一个有点不确定。是我想在所有可能的？

So I'm a bit unsure on how to proceed. Is what I want possible at all ?

推荐答案

这应该工作

var th = new Thread(() =>
{
    WebBrowserDocumentCompletedEventHandler completed = null;

    using (WebBrowser wb = new WebBrowser())
    {
        completed = (sndr, e) =>
        {
            //Do Some work

            wb.DocumentCompleted -= completed;
            Application.ExitThread();
        };

        wb.DocumentCompleted += completed;
        wb.Navigate(url);
        Application.Run();
    }
});

th.SetApartmentState(ApartmentState.STA);
th.Start();
th.Join();

这是说，我会用的 WebClient的或的 HttpWebRequest的连同 HtmlAgilityPack 下载和解析HTML资源

that said, I would use WebClient or HttpWebRequest together with HtmlAgilityPack to download and parse html resources
