Question

我没有理由对我的应用程序崩溃提出了一个问题，我只退出了退出代码 -2146233082（0x80131506）没有更多（今天看到）。所以我问StackOverflow，有人告诉我，错误是BackGroundWorker中的代码

Start.Back.PerformClick（）无法正常工作。并且没有一个BGW代码实际上在工作线程上运行。

。所以我改变它，但我会知道它是否可以因为它仍然崩溃没有任何异常和任何东西（我在Windows事件日志中看到我捕获未处理的异常）我只回忆了代码-2146233082（0x80131506），仅此而已表单关闭或结束事件被触发，它停止。。

我用作浏览器“GeckoFX”

   private void Start_Back_Click(object sender, EventArgs e)
    {                         
        List<Links> tempList = getListFromWeb();

        if (!backgroundWorker1.IsBusy)
        { 
            backgroundWorker1.RunWorkerAsync(tempGoogle);
        } 
    }

 private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        { 
            List<Links> temp = (List<Links>)e.Argument; 
            foreach (Links link in temp)
            {                 
                if (backgroundWorker1.CancellationPending)
                {
                    e.Cancel = true; return;                    
                }
                _busy.WaitOne();

                AddTabSafeThread(link.url); 

            }
            Thread.Sleep(1000); 

            SearchSafeThread(ListToSearch); 
       }


private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
        {   //Check Stuff Error and Cancelled
            if (e.Error != null)
            {... }
            else if (e.Cancelled)
            { ....}
            else //Else remove all tab
            {  
              bool canRemove = this.TabCount >= 1;
            if (canRemove)
            { 
                WebBrowserTabPage tab = this.SelectedWebBrowserTagPage; 
                this.TabPages.Remove(tab);
                tab.Dispose();
            }

             **Start.Back.PerformClick();** //Click on button again to start another time the backgroundworker 
}
    private void AddTabSafeThread(Browser tempBrowser)
    { 
        if (this.tabs.InvokeRequired)   //TabControl is tabs
        {

        this.tabs.Invoke(new m_SafeTab(AddTabSafeThread), new object[] { tempBrowser });
        }
        else
         //in TabControl Class i create the WebBrowser And i call Navigate
        {   this.tabs.addTab(tempBrowser.url);    
              //Do Stuff
        }

WebBrowser和BackGroundWorker Crash中的Invoke
