我正在使用SharpShell编写一个小的新shell上下文菜单项,将当前选定的文件复制到新的子文件夹,然后提示用户输入目录的新名称。
搜索StackOverflow,我找到this回答。但是,我想在SharpShell中做同样的事情。
我将以某种方式向SVSI_EDIT
发射SharpShell.Interop
,我可以在Pidl
深处找到它,但我不确定这是如何工作的。我无法找到任何文档或代码示例。
(编辑:我认为如何从文件名中获取task :name, [:arg, :arg] => :dependency do
...
end
将是一个良好的开端,但也许我根本不需要它?)

您可以使用 SharpShell 开始创建项目,以注册新的shell上下文菜单,如此tutorial。
在这里,我们必须定义一个实现SharpContextMenu
的类。为简单起见,我们将为任何文件类型创建菜单并始终显示它:
[ComVisible(true)]
[COMServerAssociation(AssociationType.AllFiles)]
public class CopyFilesExtension : SharpContextMenu
{
protected override bool CanShowMenu()
{
return true;
}
protected override ContextMenuStrip CreateMenu()
{
var menu = new ContextMenuStrip();
var copyFiles = new ToolStripMenuItem { Text = "Copy Files To Folder..." };
copyFiles.Click += (sender, args) => CopyFiles();
menu.Items.Add(copyFiles);
return menu;
}
private void CopyFiles()
{
...
}
}
但我确信你已经完成了所有这些,这里的问题是实现CopyFiles()
方法。
执行此操作的一种方法是显示一个对话框,询问文件夹的名称,如下所示:
然后,像这样实施CopyFiles()
:
private void CopyFiles()
{
using (var dialog = new CopyFileDialog())
{
if (dialog.ShowDialog() == DialogResult.OK)
{
var folder = Path.GetDirectoryName(SelectedItemPaths.First());
var newFolder = Path.Combine(folder, dialog.FolderName);
Directory.CreateDirectory(newFolder);
foreach (var path in SelectedItemPaths)
{
var newPath = Path.Combine(newFolder, Path.GetFileName(path));
File.Move(path, newPath);
}
}
}
}
在上面的代码中,我们询问了文件夹的名称,然后创建了文件夹,最后将所选文件移动到该文件夹。
但是,如果您想在 Windows资源管理器中使用重命名命令来执行此操作,我们可以先导入一些所需的 Win32 < / em>功能:
class Win32
{
[DllImport("shell32.dll", CharSet = CharSet.Unicode)]
public static extern IntPtr ILCreateFromPath([In, MarshalAs(UnmanagedType.LPWStr)] string pszPath);
[DllImport("shell32.dll")]
public static extern int SHOpenFolderAndSelectItems(IntPtr pidlFolder, uint cidl, IntPtr[] apidl, int dwFlags);
[DllImport("shell32.dll")]
public static extern void ILFree(IntPtr pidl);
}
ILCreateFromPath
允许我们从文件名中获取 PIDL 。SHOpenFolderAndSelectItems
允许我们选择文件并发送重命名命令。ILFree
释放未受管理的PIDL
已创建。使用这些 Win32 函数,我们可以按如下方式定义CopyFiles()
:
private void CopyFiles()
{
var folder = Path.GetDirectoryName(SelectedItemPaths.First());
var newFolder = Path.Combine(folder, "New Folder");
Directory.CreateDirectory(newFolder);
foreach (var path in SelectedItemPaths)
{
var newPath = Path.Combine(newFolder, Path.GetFileName(path));
File.Move(path, newPath);
}
RenameInExplorer(newFolder);
}
private static void RenameInExplorer(string itemPath)
{
IntPtr folder = Win32.ILCreateFromPath(Path.GetDirectoryName(itemPath));
IntPtr file = Win32.ILCreateFromPath(itemPath);
try
{
Win32.SHOpenFolderAndSelectItems(folder, 1, new[] { file }, 1);
}
finally
{
Win32.ILFree(folder);
Win32.ILFree(file);
}
}
我们无法使用SharpShell.Interop.Shell32
,因为此类中唯一可用的方法是ShellExecuteEx()
,用于启动新进程。

使用问题中cited example的SelectItemInExplorer
功能,非常基本实现如下所示。尽可能重写任何P / Invoke功能,以尽可能多地使用SharpShell的现有声明。
