从 Windows 桌面获取所选文件的列表 [英] Get list of selected files from Windows Desktop

问题描述

我正在尝试从 Windows 桌面和资源管理器 Windows 获取所选文件的列表.要求是我应该能够从活动的资源管理器窗口或桌面检索当前选择.

I am trying to get a list of selected files from the Windows Desktop and the Explorer Windows. The requirement is that I should be able to retrieve the current selection from the active explorer window or the Desktop.

在浏览了在线资源后，我设法将以下代码组合在一起，但它没有提供桌面中所选项目的列表.

I have managed to put together the following code, after going through online resources, but it does not provide a list of selected items from the Desktop.

ArrayList selected = new ArrayList();
var shell = new Shell32.Shell();
IntPtr handle = IntPtr.Zero;
handle = GetForegroundWindow();
int intHandle = handle.ToInt32();

//For each explorer
foreach (InternetExplorer window in new ShellWindowsClass())
{

    if (window.HWND == (int)handle)
    {
        Shell32.FolderItems items = ((Shell32.IShellFolderViewDual2)window.Document).SelectedItems();
        foreach (Shell32.FolderItem item in items)
        {
            selected.Add(item.Path);
        }
    }
}

除此之外，我尝试了以下操作，但它只提供了所有打开的资源管理器窗口中所有选定元素的列表，而忽略了桌面.

Other than that, I tried the following but it just gives a list of all selected elements in all open explorer windows while ignoring the Desktop.

string filename; = Path.GetFileNameWithoutExtension(window.FullName).ToLower();
if (filename.ToLowerInvariant() == "explorer")
{
    Shell32.FolderItems items = ((Shell32.IShellFolderViewDual2)window.Document).SelectedItems();
    foreach (Shell32.FolderItem item in items)
    {
        //MessageBox.Show(item.Path.ToString());
        selected.Add(item.Path);
    }
}

所以我总是以资源管理器窗口中的列表结束，即使没有打开资源管理器窗口也没有得到任何结果.当前的技术似乎完全忽略了桌面.

So I just always end up with a list from the explorer windows and get no results even when no explorer windows are open. The current techniques seem to be ignoring the Desktop altogether.

如果有人能帮我从当前活动的窗口/桌面中获取所选文件的列表，我将不胜感激.

I would really appreciate it if someone could help me out to get a list of selected files from the currently active window/desktop.

谢谢.

推荐答案

桌面很容易，因为它仍然是一个列表视图，只需找到正确的句柄.列表视图是桌面句柄的子视图.

It is easy for desktop since it is still a listview, just find the correct handle. list view is a child of the desktop handle.

Desktop
+- Progman (for backward compatibility)
   +- Shell Def View
      +- SysListView32 (even under 64 bit)

那么你就可以在列表视图上做所有的列表视图操作了.但其他资源管理器窗口不包含列表视图.相反，他们使用带有 DirectUIHWND 类的窗口，这对许多人来说是个谜.我刚刚找到了一篇文章，描述了解开这个谜团的方法.

then you can do all listview operations on the list view. but other explorer windows does not contain a list view. Instead they use window with class DirectUIHWND which is a mystery to many. I've just found a post that describes a way to the unravel that mystery.
