C＃的背景線程＃

我正在開發一個C＃windows軟件。我想同時在那裏運行6個Web瀏覽器。在每個瀏覽器中有6個不同的網站導航，我想同時填充它們的值。 使用線程所有瀏覽器正在運行並且網站正確導航。但我的問題是，價值在每個瀏覽器中逐一填充。請建議我我如何同時填補所有值在每個站點，也後臺線程（在隱藏模式下，線程運行）C＃的背景線程＃

/*這裏frmBz是MDI父

這裏我只放了兩個功能，因爲空間不足

我正在使用這個

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);

要啓動主題 * selectedwebsites是列表 *

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

您能否顯示您遇到問題的代碼？ –

Web瀏覽器是否以單一形式託管？ –

+0

@Erno是的，我採取了單一的表單名稱（frmBrowser1），並有一個web瀏覽器。我還採取另一種形式（frmBrowser），它是MDI的父項。我在每個函數中創建了frmbrowser1的實例（代碼中顯示），並使其成爲frmBrowser形式的子項。請檢查代碼。 – Neetesh

下面是裸露的基本知識，在自己的線程運行Method WebSiteOne。 我建議你閱讀關於線程，有很多很好的例子來開始。

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(); 
}

我認爲導航後我使用Application.doEvent（），所以它可能會逐一完成 – Neetesh

也許你已經添加一個後臺線程，然後打開瀏覽器一一在此線程？

嘗試System.Threading.Threadpool.QueueUserWorkItem()然後把你的電話打到瀏覽器中。

其導航所有6個網站6網絡瀏覽器，但它並沒有在所有瀏覽器中同時填寫細節。它一個接一個。我使用Application.DOEvent可能是這是原因 – Neetesh

你爲什麼用這個瀏覽器？你不能直接使用HTTP請求到服務器嗎？瀏覽器只提供一個用戶界面，只有在我認爲應該填寫「人」時才需要。

在你的情況下，如果你提交數據的網站會公開你作爲某種web服務填寫的表單（但這是最好的情況:)）。

我有大約100個網站，我想提交的數據使用軟件。所以我正在使用線程，並希望使用後臺線程 – Neetesh

如果你有這麼多的網站（假設你自己維護它們），爲什麼你不公開一個web服務，所以你可以讓你的請求服務，而不是調用另一個處理您的請求。擁有服務將使您的代碼更容易閱讀和維護 – thekip

不，我不維護網站，我只是自動化他們。 – Neetesh

問題是您的線程根本沒有任何有用的工作，因爲他們立即將所有相關的東西封送回UI線程。我在下面縮短了您的代碼，使其更易於查看。

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. 
    } 
}

通知輔助線程立即電話如何Control.Invoke任何實際工作發生之前遞歸地重新輸入UI線程的方法。最重要的是，工作線程實際上等待UI線程在工作線程本身終止之前完成。從一開始，因爲創建新線程不過是浪費資源而已，從一開始就只是在UI線程上執行所有操作，效果更糟糕。

天真的解決方案是在工作線程中省略對Control.Invoke的調用並讓它完成所有工作。但是，唉，由於大多數有用的工作都需要對UI元素進行操作，所以這也不起作用，因爲您可能知道，UI元素除了UI線程之外都被禁止。你將不得不從根本上改變你的策略。
