# 1. Example 1: Creating a GUI form using .NET classes

#This PowerShell script demonstrates how to create a simple GUI form using .NET classes. The form contains a label, text box, and button. When the button is clicked, the text entered in the text box is displayed in the label.

# Load .NET assembly for creating GUI forms
Add-Type -AssemblyName System.Windows.Forms

# Create a new form object
$form = New-Object System.Windows.Forms.Form

# Set form properties
$form.Text = "My Form"
$form.Size = New-Object System.Drawing.Size(300, 200)

# Create label object and add to form
$label = New-Object System.Windows.Forms.Label
$label.Location = New-Object System.Drawing.Point(10, 10)
$label.Text = "Enter text:"
$form.Controls.Add($label)

# Create text box object and add to form
$textbox = New-Object System.Windows.Forms.TextBox
$textbox.Location = New-Object System.Drawing.Point(10, 30)
$form.Controls.Add($textbox)

# Create button object and add to form
$button = New-Object System.Windows.Forms.Button
$button.Location = New-Object System.Drawing.Point(10, 60)
$button.Text = "Display Text"
$form.Controls.Add($button)

# Add event handler for button click event
$button.Add_Click({
    $label.Text = $textbox.Text
})

# Show the form
$form.ShowDialog()

2. Example 2: Using .NET classes to interact with Windows Registry

This PowerShell script demonstrates how to use .NET classes to read and write values in the Windows Registry.

# Load .NET assembly for working with registry keys/values
Add-Type -AssemblyName Microsoft.Win32.Registry

# Define registry key path and value name
$keyPath = "HKCU:\Software\MyApp"
$valueName = "MyValue"

# Check if registry key exists; create it if it doesn't exist
if (!(Test-Path $keyPath)) {
    [Microsoft.Win32.Registry]::CurrentUser.CreateSubKey("Software\MyApp")
}

# Write value to registry key
[Microsoft.Win32.Registry]::SetValue($keyPath, $valueName, "Hello World")

# Read value from registry key and display it in console output
$value = [Microsoft.Win32.Registry]::GetValue($keyPath, $valueName)
Write-Host "Value read from registry: $value"

3. Example 3: Using .NET classes to interact with Active Directory

This PowerShell script demonstrates how to use .NET classes to query Active Directory for user information.

# Load .NET assembly for working with Active Directory objects/classes
Add-Type -AssemblyName System.DirectoryServices.AccountManagement

# Define domain name and user name to search for
$domainName = "mydomain.local"
$userName = "jdoe"

# Create principal context object for domain authentication/authorization
$contextType =[System.DirectoryServices.AccountManagement.ContextType]::Domain
$principalContext =[System.DirectoryServices.AccountManagement.PrincipalContext]::new($contextType,$domainName)

if ($principalContext) {
    # Find user by username
    $userPrincipal =[System.DirectoryServices.AccountManagement.UserPrincipal]::FindByIdentity($principalContext,$userName)

    if ($userPrincipal) {
        # Display user properties in console output
        Write-Host "User found: $($userPrincipal.Name)"
        Write-Host "Email address: $($userPrincipal.EmailAddress)"
        Write-Host "Last logon date: $($userPrincipal.LastLogonDate)"
    }
    else {
        Write-Host "User not found."
    }
}
else {
    Write-Host "Unable to connect to domain."
}
