Wie kann ich meine exe ausführen Via Powershell?

Since Powershell does not generate an error message in your case, your program seems to be started at least successfully (to stop yourself without any message)

If you run your program via “Start-Process”, this happens in another window. If the program does not itself have mechanisms to keep the relevant window open, it may snap so quickly that you do not get any (error) messages to face!

Start process is used only if the result of the program execution should not have any influence on the calling script. (apart from -Wait)

Should the called program operate its issues within the console of the running script, use the & call operator or .-dotsourcing .

Demo.ps1

$Code = @'
using System;
class TestProg{
    public static void Main(string[] args){
        Console.WriteLine("Hallo Welt");
        Console.WriteLine("...beliebige Taste zum Beenden");
        Console.ReadKey(); //Fenster offen halten
    }
}
'@


$ProgramPath=".\Hallo Welt.exe"
 #unser kleines Beispielprogramm Quick&Dirty compilieren (funktioniert nicht  mit Powershell 6 und  höher!)
Add-Type -typeDefinition $Code  -OutputType ConsoleApplication -OutputAssembly "Hallo Welt.exe" 


#Aufrufen von (nichtsystem)-Programmen in Powershell
 #parallel/entkoppelt zum aufrufenden Powershell-Prozess (eigenes Fenster,Environment, etc.)
Start-Process -FilePath $ProgramPath -wait


 #innerhalb von Powershell in einem untergeordneten (wirkungs)Bereich (childscope)
& $ProgramPath


 #innerhalb von Powershell im aktuellen Scope
. $ProgramPath
pause

…who needs VisualStudio to compile C#? 😅

There’s someone hanging out of the window.

Look at my “playground”:

In Batch and Powershell, you should certainly not try to measure with me!
