获取当前选择WindowsExplorer从C＃应用程序？ [英] Get current selection in WindowsExplorer from a C# application?

问题描述

时有可能得到，目前在Windows资源管理器中选择从我的C＃应用​​程序的文件列表？

Is it possible to get a list of the files that are currently selected in Windows Explorer from my C# app?

我已经与Windows资源管理器，如C＃托管语言交互的不同方法进行了大量的研究。起初，我在这里看着外壳扩展的实现（和的here 为例），但显然这是从内部管理code一个坏主意，可能是矫枉过正反正我的情况。

I have done a lot of research on different methods of interacting with Windows Explorer from a managed language like C#. Initially, I was looking at implementations of shell extensions (here and here for example), but apparently that is a bad idea from within managed code, and is probably overkill for my situation anyway.

接下来，我看着的PInvoke / COM解决方案，并发现这篇文章，这使我这个code：

Next, I looked into PInvoke/COM solutions, and found this article, which led me to this code:

        SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();

        string filename;
        ArrayList windows = new ArrayList();

        foreach(SHDocVw.InternetExplorer ie in shellWindows)
        {
            filename = Path.GetFileNameWithoutExtension(ie.FullName).ToLower();
            if(filename.Equals("explorer"))
            {
                Console.WriteLine("Hard Drive: {0}", ie.LocationURL);
                windows.Add(ie);

                var shell = new Shell32.Shell();
                foreach (SHDocVw.InternetExplorerMedium sw in shell.Windows())
                {
                    Console.WriteLine(sw.LocationURL);
                }

            }
        }

...但个别的InternetExplorer 对象有没有方法来获得当前的文件选择，虽然他们可以用来获取有关窗口的信息。

...But the individual InternetExplorer objects have no methods to get the current file selection, though they can be used to get information about the window.

然后我发现这篇文章做正是我需要的，但在C ++。以此为出发点，我试图通过添加 SHELL32.DLL 在我的项目的引用，做一些翻译。我结束了以下内容：

Then I found this article doing exactly what I needed, but in C++. Using this as a starting point, I attempted to do some translation by adding shell32.dll as a reference in my project. I ended up with the following:

        SHDocVw.ShellWindows shellWindows = new SHDocVw.ShellWindows();

        string filename;
        ArrayList windows = new ArrayList();

        foreach(SHDocVw.InternetExplorer ie in shellWindows)
        {
            filename = Path.GetFileNameWithoutExtension(ie.FullName).ToLower();
            if(filename.Equals("explorer"))
            {
                Console.WriteLine("Hard Drive: {0}", ie.LocationURL);
                windows.Add(ie);
                var shell = (Shell32.IShellDispatch4)new Shell32.Shell();
                Shell32.Folder folder = shell.NameSpace(ie.LocationURL);
                Shell32.FolderItems items = folder.Items();
                foreach (Shell32.FolderItem item in items)
                {
                    ...
                }
            }
        }

这是稍微靠近，因为我能够得到的窗口文件夹对象，并为每个项目，但我还是不明白的方式来获得当前的选择。

This was slightly closer, because I am able to get a Folder object for the window, and for each item, but I still do not see a way to get the current selection.

我可能会寻找完全错了地方，但我一直在关注的唯一线索我。任何人都可以点我到适当的PInvoke / COM解决方案？

I may be looking entirely in the wrong place, but I've been following the only leads I have. Can anyone point me to the appropriate PInvoke/COM solution?

推荐答案

终于想出了一个解决方案，这要归功于这个问题：的获取选定文件夹中的项目与WinAPI的。

Finally figured out a solution, thanks to this question: Get selected items of folder with WinAPI.

我结束了以下内容，在为了得到当前所选的文件的列表：

I ended up with the following, in order to get a list of currently selected files:

IntPtr handle = GetForegroundWindow();

List<string> selected = new List<string>();
var shell = new Shell32.Shell();
foreach(SHDocVw.InternetExplorer window in shell.Windows())
{
    if (window.HWND == (int)handle)
    {
        Shell32.FolderItems items = ((Shell32.IShellFolderViewDual2)window.Document).SelectedItems();
        foreach(Shell32.FolderItem item in items)
        {
            selected.Add(item.Path);
        }
    }
}

显然 window.Document 对应的资源管理器窗口，这是不是很直观里面实际的文件夹视图。但不是误导性的变量/方法的名称等，这个完美的作品。

Apparently window.Document corresponds to the actual folder view inside the explorer window, which isn't very intuitive. But other than the misleading variable/method names, this works perfectly.
