我正在开发一个软件C＃windows。我想同时在那里运行6个网络浏览器。每个浏览器都有6个不同的网站导航，我想同时填写它们的价值。 使用线程所有浏览器都在运行，网站正常导航。但我的问题是，每个浏览器中的值都是逐个填充的。请建议我如何在每个站点同时填充所有值以及背景线程（线程以隐藏模式运行）

为什么要使用浏览器呢？你不能直接向服务器使用HTTP请求吗？浏览器只提供一个UI，只有在我认为“人”应填写字段时才需要。
在您的情况下，最好是您提交数据的网站会将您填写的表格公开为某种类型的网络服务（但这是最好的情况:)）。

以下是在自己的线程中运行Method WebSiteOne的基础知识。
我建议你阅读一下线程，有许多好的例子可以开始。
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();
}

也许你已经添加了一个后台线程，然后在这个帖子中逐个打开浏览器？
尝试System.Threading.Threadpool.QueueUserWorkItem()然后将您的呼叫拨入此浏览器。
答案 3 :(得分：1)
问题是你的线程根本没有任何有用的工作，因为它们会立即将所有相关的东西编组回UI线程。我已经缩短了下面的代码，以便于查看。
void bbyp_com()
{
frmBrowser1 frmB = new frmBrowser1();
try
{
if (InvokeRequired)
{
this.Invoke(new MethodInvoker(bbyp_com));
return;
}
// All of the useful work happens here.
}
catch
{
// Stuff omitted here for brevity.
}
}
注意工作线程如何在任何实际工作发生之前立即调用Control.Invoke以递归重新进入UI线程上的方法。最重要的是，工作线程实际上等待UI线程在工作线程本身终止之前完成。效果比 1 更糟糕，因为从一开始就在UI线程上做了所有事情，因为创建了一个新线程，只不过是浪费资源。
天真的解决方案是省略对工作线程中Control.Invoke的调用，让它完成所有工作。但唉，这也行不通，因为大多数有用的工作都需要对UI元素做一些事情，正如你可能知道的那样，UI元素以外的任何东西都是禁止的。
你必须从根本上改变你的策略。
