$smtpServer = “smtp.example.com”
$mailFrom = “[email protected]”
$mailTo = “[email protected]”
$subject = “Test email from PowerShell”
$body = “This is a test email sent using PowerShell and .NET Framework.”
$mailMessage = New-Object System.Net.Mail.MailMessage $mailFrom, $mailTo
$mailMessage.Subject = $subject
$mailMessage.Body = $body
$smtp = New-Object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($mailMessage)
“`
4. PowerShell Cmdlets and Advanced Functions
One of the defining characteristics of PowerShell is the concept of cmdlets (pronounced “command-lets”). Cmdlets are .NET classes and functions that can be accessed through PowerShell as simple commands. Users can create custom cmdlets by extending System.Management.Automation.Cmdlet class, which is part of the .NET Framework.
Additionally, PowerShell provides advanced functions, also known as script cmdlets, which mimic the behavior and structure of compiled cmdlets without the necessity of creating a .NET assembly. These functions allow users to harness the power of the .NET Framework within their scripts, without extensive knowledge of C# or Visual Basic programming.
5. Extending PowerShell with .NET Assemblies
PowerShell’s reliance on the .NET Framework extends beyond accessing libraries and classes. Users can create custom .NET assemblies that extend PowerShell’s functionality even further. By developing modules and snap-ins, users can create a tailored experience that caters to their specific automation and scripting requirements.
For example, imagine you have developed a .NET assembly that interacts with a specific database system. Instead of rewriting your code entirely in PowerShell, you can create a custom cmdlet or module that interacts with your .NET code, thereby making it accessible within PowerShell.
To sum up, not only is PowerShell built on the .NET Framework, but its integration with the framework allows for a powerful scripting language that leverages the capabilities of .NET. From accessing .NET classes and libraries to creating custom cmdlets and modules, PowerShell has become an indispensable tool for automation enthusiasts and developers alike. By understanding the intricate relationship between PowerShell and the .NET Framework, you can fully utilize the potential that this connection offers.
