在访问Process.MainWindowTitle如下...

When accessing Process.MainWindowTitle as follows...

Process[] processes = Process.GetProcessesByName( "iexplore" );

...然后遍历结果数组，我总是最后的 MainWindowTitle 是空的阵列中的所有，但一个项目。就我而言，我有两个Internet Explorer窗口打开，其中一个单独的标签，一个在它两个选项卡。

...and then loop over the resulting array, I always end up with the MainWindowTitle being empty for all but one item in the array. In my case I've got two Internet Explorer windows open, one with a single tab and one with two tabs in it.

运行我的code我总是得到MainWindowTitle的，我有最后一个活动的窗口和标签 - 所有的人保持空白。奇怪的是，在该MainWindowTitle充满进程ID总是一样的 - 如果我启动运行我的code之前，其他IE浏览器窗口或标签，进程ID总是相同的：

Running my code I always get the MainWindowTitle for the window and tab that I had last active - all the others remain empty. The strange thing is that the process ID in which the MainWindowTitle is filled is always the same - if I activate the other IE window or tab before running my code, the process ID is always the same:

  if ( !processes.Any() )
  {
    MessageBox.Show( "TODO - No matching process found" );
    return;
  }

  if ( processes.Count() > 1 )
  {
    foreach ( Process currentProcess in processes )
    {
      // More than one matching process found
      checkedListBox1.Items.Add( currentProcess.Id + " - " + currentProcess.MainWindowTitle + " - " + currentProcess.ProcessName );
    }

    return;
  }

因此​​，输出可能是第一次运行，如：

Output could therefore be for the first run like:

4824 - - IEXPLORE 3208 - - IEXPLORE 4864 - 谷歌 - Windows Internet Explorer的 - IEXPLORE

下次运行（与事先选择的其他IE窗口）：

Next run (with the other IE window selected beforehand):

4824 - - IEXPLORE 3208 - - IEXPLORE 4864 - id Software公司 - 的​​Windows Internet Explorer - IEXPLORE

我读过关于this帖子，但我没有得到任何进一步的与我的问题（而且似乎进入一个有所不同的方向是这样）。

I've read about this post, but I didn't get any further with my problem (and it seems to go into a somewhat different direction anyway).

为什么我总是只能得到一个非空MainWindowTitle？

Why do I always only get one non-empty MainWindowTitle?

推荐答案

一个选项，以实现这一目标reliabely（见上述评论）是实施的 BHO - ESP。在 DWebBrowserEvents2 :: WindowStateChanged 事件是有用的在这种情况下。

One option to make this happen reliabely (see comments above) is to implement a BHO - esp. the DWebBrowserEvents2::WindowStateChanged Event is usefull in this scenario.

BHO是一堆COM接口的实现，并获得加载到浏览器进程/每个标签......实现它们在C ++ IMO最好的方式。

BHOs are implementations of a bunch of COM interfaces and get loaded into the browser process/each tab... best way to implement them is in C++ IMO.

但肯定是可以这样做的。NET（虽然不推荐）：

But it is certainly possible to do so in .NET (although not recommended):
