在选项卡从C＃现有的IE窗口中启动URL

问题描述

下面code打开一个链接在现有的浏览器窗口时browserExe指向火狐，Safari或Chrome。当指向IEXPLORE.EXE（IE7）一个新的窗口被打开。

The following code opens a link in an existing browser window when browserExe is pointing to Firefox, Safari or Chrome. When pointing to IEXPLORE.EXE (IE7) a new windows is opened.

ProcessStartInfo pi = new ProcessStartInfo(browserExe, url);
Process.Start(pi);

这将打开现有的窗口，一个标签如预期，当IE为默认浏览器。

This opens a tab in an existing window as intended, when IE is the default browser.

ProcessStartInfo pi = new ProcessStartInfo(url);
Process.Start(pi);

如何我重用现有的IE窗口，当IE是不是默认的浏览器？

How to i reuse an existing IE windows, when IE is NOT the default browser?

推荐答案

使用SHDOCVW库（在此提及它，你可以找到它在Windows \ System32下），你可以得到实例的列表，并调用导航与newtab参数：

Using shdocvw library (add reference to it, you can find it in windows\system32) you can get the list of instances and call navigate with the newtab parameter:

ShellWindows iExplorerInstances = new ShellWindows();
if (iExplorerInstances.Count > 0)
{
  IEnumerator enumerator = iExplorerInstances.GetEnumerator();
  enumerator.MoveNext();
  InternetExplorer iExplorer = (InternetExplorer)enumerator.Current;
  iExplorer.Navigate(url, 0x800); //0x800 means new tab
}
else
{
  //No iexplore running, use your processinfo method
}

编辑：在某些情况下，你可能要检查shellwindow对应于一个真实的IEXPLORER一个没有任何其他的Windows外壳程序（W7中的所有实例都回来了，不知道现在的人）

---

in some cases you may have to check if the shellwindow corresponds to a real iexplorer an not to any other windows shell (in w7 all instances are returned, don't know now for others).

   bool found=false;
   foreach (InternetExplorer iExplorer in iExplorerInstances)
   {
       if (iExplorer.Name == "Windows Internet Explorer")
       {
           iExplorer.Navigate(ur, 0x800);
           found=true;
           break;
       }
   }
   if(!found)
   {
      //run with processinfo
   }
