Wählen Sie bestimmte Dateien im Explorer mit Powershell

Question

I spezifischen mehrere Dateien im Windows-Explorer tun auswählen möchten, dass ich diese verwendet:

explorer.exe/select „c: \ Pfad \ Datei zu \ .txt“

In PowerShell habe ich diese:

$filenames = @("D:\imgs\a.jpg", "D:\imgs\b.jpg") 
foreach($fl in $filenames) 
{ 
Start-Process -FilePath C:\Windows\explorer.exe -ArgumentList "/select, ""$fl""" 
} 

es funktioniert gut, aber zwei explorer.exe werden zur gleichen Zeit für jede Dateien im Array $filenames ausgeführt. Ich möchte ausgewählte Dateien in einem einzelnen Explorer abrufen.

Answer 1

Im selben Explorer-Befehl können Sie nicht mehrere Datei/Ordner-Auswahl verwenden, aber wir können die Funktion SHOpenFolderAndSelectItems in shell32.dll dafür verwenden. Ich habe eine C# in Powershell-Schnipsel eingewickelt (original C# Kern: https://gist.github.com/vbfox/551626)

Die hier Zeichenfolge mit dem C# -Code:
