我必须做的最困难的事情之一是使用PowerShell访问Windows API。我想使用Shell32.dll中的API擦除回收站。还有其他方法,但它们通常绕过正常的Windows进程,在这种情况下,我想以“正确”的方式做到这一点。
几个小时后,我想出了这个。
$TypeDefinition=@"
using System;
using System.ComponentModel;
using System.Runtime.InteropServices;
namespace shell32 {
//Put all the variables required for the DLLImports here
enum RecycleFlags : uint { SHERB_NOCONFIRMATION = 0x00000001, SHERB_NOPROGRESSUI = 0x00000002, SHERB_NOSOUND = 0x00000004 }
public static class RecycleBin {
[DllImport("Shell32.dll",CharSet=CharSet.Unicode)]
internal static extern uint SHEmptyRecycleBin(IntPtr hwnd, string pszRootPath, RecycleFlags dwFlags);
}
public class ShellWrapper : IDisposable {
// Creates a new wrapper for the local machine
public ShellWrapper() { }
// Disposes of this wrapper
public void Dispose() {
GC.SuppressFinalize(this);
}
//Put public function here
public uint Empty() {
uint ret = RecycleBin.SHEmptyRecycleBin(IntPtr.Zero, null, RecycleFlags.SHERB_NOCONFIRMATION | RecycleFlags.SHERB_NOPROGRESSUI | RecycleFlags.SHERB_NOSOUND);
return ret;
}
// Occurs on destruction of the Wrapper
~ShellWrapper() {
Dispose();
}
} //Wrapper class
}
"@
Add-Type -TypeDefinition $TypeDefinition -PassThru | out-null
$RecycleBin=new-object Shell32.ShellWrapper
$RecycleBin.Empty()
这个怎么样?不重置任何权限,适用于所有用户和所有驱动器。我在2012 R2 +上测试了它
$dis = gwmi Win32_LogicalDisk -Filter 'DriveType=3' | select -ExpandProperty DeviceID
$rec = @()
foreach ($d in $dis)
{
$rec += gci "$d\`$Recycle.Bin" -Force
}
foreach ($r in $rec)
{
gci $r.FullName -Force -Recurse | rm -Force -Confirm:$false
}
