使用Powershell以编程方式清除回收站

问题描述 投票:4回答:2

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。

c# winapi powershell recycle-bin shell32.dll

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
}
