我正在开发一个C＃windows软件。我想同时在那里运行6个Web浏览器。在每个浏览器中有6个不同的网站导航，我想同时填充它们的值。 使用线程所有浏览器正在运行并且网站正确导航。但我的问题是，价值在每个浏览器中逐一填充。请建议我我如何同时填补所有值在每个站点，也后台线程（在隐藏模式下，线程运行）C＃的背景线程＃

/*这里frmBz是MDI父

这里我只放了两个功能，因为空间不足

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); 

Thread m_thread3 = new Thread(new ThreadStart(ezlocal_com)); 
m_thread3.SetApartmentState(ApartmentState.STA); 

Thread m_thread4 = new Thread(new ThreadStart(merchantcircle_com)); 
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);

要启动主题 * selectedwebsites是列表 *

while (selectedwebsites.Count > 0) 
{ 
    try 
    { 
     if (selectedwebsites[j] == "hotfrog.com") 
     { 
      counter++; 
      m_thread1.Start(); 
      selectedwebsites.RemoveAt(j); 
      break; 
     } 

     if (selectedwebsites[j] == "local.yahoo.com") 
     { 
      counter++; 
      m_thread2.Start(); 
      selectedwebsites.RemoveAt(j); 
      break; 
     } 

     if (selectedwebsites[j] == "ezlocal.com") 
     {

您能否显示您遇到问题的代码？ –

Web浏览器是否以单一形式托管？ –

+0

@Erno是的，我采取了单一的表单名称（frmBrowser1），并有一个web浏览器。我还采取另一种形式（frmBrowser），它是MDI的父项。我在每个函数中创建了frmbrowser1的实例（代码中显示），并使其成为frmBrowser形式的子项。请检查代码。 – Neetesh

下面是裸露的基本知识，在自己的线程运行Method WebSiteOne。 我建议你阅读关于线程，有很多很好的例子来开始。

Thread threadWebSiteOne = new Thread(new ThreadStart(WebSiteOne)); 
threadWebSiteOne.Start();

使用BackGroundWorker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(); 
}

线程m_thread1 = new线程（新的ThreadStart（hotfrog_com））; m_thread1.SetApartmentState（ApartmentState.STA）; – Neetesh

我认为导航后我使用Application.doEvent（），所以它可能会逐一完成 – Neetesh

也许你已经添加一个后台线程，然后打开浏览器一一在此线程？

尝试System.Threading.Threadpool.QueueUserWorkItem()然后把你的电话打到浏览器中。

其导航所有6个网站6网络浏览器，但它并没有在所有浏览器中同时填写细节。它一个接一个。我使用Application.DOEvent可能是这是原因 – Neetesh

你为什么用这个浏览器？你不能直接使用HTTP请求到服务器吗？浏览器只提供一个用户界面，只有在我认为应该填写“人”时才需要。

在你的情况下，如果你提交数据的网站会公开你作为某种web服务填写的表单（但这是最好的情况:)）。

我有大约100个网站，我想提交的数据使用软件。所以我正在使用线程，并希望使用后台线程 – Neetesh

如果你有这么多的网站（假设你自己维护它们），为什么你不公开一个web服务，所以你可以让你的请求服务，而不是调用另一个处理您的请求。拥有服务将使您的代码更容易阅读和维护 – thekip

不，我不维护网站，我只是自动化他们。 – Neetesh

问题是您的线程根本没有任何有用的工作，因为他们立即将所有相关的东西封送回UI线程。我在下面缩短了您的代码，使其更易于查看。

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. 
    } 
}

通知辅助线程立即电话如何Control.Invoke任何实际工作发生之前递归地重新输入UI线程的方法。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。从一开始，因为创建新线程不过是浪费资源而已，从一开始就只是在UI线程上执行所有操作，效果更糟糕。

天真的解决方案是在工作线程中省略对Control.Invoke的调用并让它完成所有工作。但是，唉，由于大多数有用的工作都需要对UI元素进行操作，所以这也不起作用，因为您可能知道，UI元素除了UI线程之外都被禁止。你将不得不从根本上改变你的策略。
