后台线程C#
后台线程C#
提问于 2011-07-27 06:38:29
我正在开发一个软件C#窗口。我想同时运行那里的6个网页浏览器。有6个不同的网站导航在每个浏览器，我想在他们同时填充值。使用线程，所有浏览器都在运行，网站导航正确。但我的问题是，这个值是在每个浏览器中一个一个地填充。请建议我如何同时填充每个站点中的所有值以及后台线程(线程以隐藏模式运行)。

}这里的/* frmBz是MDi的父级
这里我只放了两个函数，因为空间很小
我正在使用这个
Thread m_thread1 = new Thread(new ThreadStart(hotfrog_com));
m_thread1.SetApartmentState(ApartmentState.STA);
Thread m_thread2 = new Thread(new ThreadStart(yahoolocal_com));
m_thread2.SetApartmentState(ApartmentState.STA);

m_thread4.SetApartmentState(ApartmentState.STA);
Thread m_thread5 = new Thread(new ThreadStart(yellowusa_com));
m_thread5.SetApartmentState(ApartmentState.STA);
Thread m_thread6 = new Thread(new ThreadStart(bbyp_com));
m_thread6.SetApartmentState(ApartmentState.STA);启动线程*选择的网站是list*

下面是在自己的线程中运行Method WebSiteOne的基本知识。我建议你阅读一下线程，有很多很好的例子可以开始。
Thread threadWebSiteOne = new Thread(new ThreadStart(WebSiteOne));
threadWebSiteOne.Start();使用BackGroundWorker进行更新。
BackgroundWorker bw = new BackgroundWorker();
bw.DoWork += bw_DoWork;
bw.RunWorkerCompleted += bw_RunWorkerCompleted; //Gets called when work completed
bw.RunWorkerAsync();
static void bw_DoWork (object sender, DoWorkEventArgs e) {
//Load Webpage X EG : hotfrog_com();

你为什么要用浏览器来做这个？您不能直接对服务器使用HTTP请求吗？浏览器只是提供一个UI，这是需要的，只有‘人’应该填写字段在我看来。
在您的情况下，如果您提交数据的网站将您正在填写的表单公开为某种形式的best服务(不过，这是最好的案例场景：)，这将是最好的。

也许您已经添加了一个后台线程，然后在这个线程中逐个打开浏览器？
尝试System.Threading.Threadpool.QueueUserWorkItem()，然后将您对浏览器的调用放在下面。
