GetProc01-codevoorbeeld (C#)

De volgende code toont de implementatie van de GetProc01-voorbeeld-cmdlet. U ziet dat de cmdlet wordt vereenvoudigd door het werkelijke proces ophalen over te laten aan de methode System.Diagnostics.Process.Getprocesses*.

Notitie

U kunt het C#-bronbestand (getproc01.cs) voor deze Get-Proc-cmdlet downloaden met behulp van de Microsoft Windows Software Development Kit voor Windows Vista en .NET Framework 3.0 Runtime Components.

using System.Management.Automation;             //Windows PowerShell namespace

using System.ComponentModel;

// This sample shows how to create a simple cmdlet. To test this 
// cmdlet, the snapin must be registered.  First, run the command:
//     installutil GetProcessSample01.dll
// Then run:
//     Add-PSSnapin GetProcessSnapIn01
// After the snapin has been loaded, you can run:
//     get-proc
