PowerShell: How to Create and Use Classes

PowerShell has the capability to create .Net Framework classes using the Add-Type Jump cmdlet. To create classes, the C# language can be used to define the classes. C# is part of Visual Studio, but having Visual Studio is not necessary to create classes for use in PowerShell. The C# class definitions can be part of the PowerShell script file. No DLL files to worry about installing.

$PeopleDefinition=@"
using System;
using System.Collections;
using System.Collections.Generic;

namespace People
{
    public enum Gender

    {
        Unknown,
        Male,
        Female
    }

    public class Person  {}
    public class Persons {}
    public class People  {}
    public static class Factory {}
}
"@

Add-Type -TypeDefinition $PeopleDefinition
Remove-Variable PeopleDefinition
$People = [People.Factory]::BuildPeople()
$Person = $People["Person"]

.NET Namespace-Powershell

All Scripts in this Blog written using .NET Namespace so we don't have the Module Dependency.

Now a days there are so many Modules are available in Powershell. For our daily operation those are very helpful.If we using built-in Module there are few challenges like If we are used "ActiveDirectory" Module; that module is available in Domain Controler or you need to install that manually. In this case if we want manage our AD; we need "ActiveDirectory" Module. That is the reason I am putting this topic in this blog. If you are used .NET namespace you don't need the Module.

If we are used .NET name space instead of Powershell Module which is available in all Windows 2008 System. Also we don't have any Module available in Windows 2008 for manageing the Microsoft PKI.

Given few important Namespaces those can make our life easier & we can write our own code without the Powershell Module.

1. We can manage our Active Directory

NameSpace
[System.DirectoryServices.ActiveDirectory]
