Simple - Give 3 example powershell scripts that shows "how to work with .NET Classes"

1. Example 1: Using .NET classes to manipulate files and directories

# This script demonstrates how to use .NET classes to manipulate files and directories

# Create a new directory
$dirPath = "C:\Temp\NewDirectory"
[System.IO.Directory]::CreateDirectory($dirPath)

# Create a new file
$filePath = "C:\Temp\NewDirectory\NewFile.txt"
[System.IO.File]::Create($filePath)

# Write some text to the file
$fileContent = "This is some text that will be written to the file."
[System.IO.File]::WriteAllText($filePath, $fileContent)

# Read the contents of the file
$fileContent = [System.IO.File]::ReadAllText($filePath)
Write-Host $fileContent

# Delete the file and directory
[System.IO.File]::Delete($filePath)
[System.IO.Directory]::Delete($dirPath)


2. Example 2: Using .NET classes to work with dates and times

# This script demonstrates how to use .NET classes to work with dates and times

# Get the current date and time
$currentDateTime = Get-Date

# Display the current date and time in various formats
Write-Host "Current date and time:"
Write-Host "   Long date format: $($currentDateTime.ToLongDateString())"
Write-Host "   Short date format: $($currentDateTime.ToShortDateString())"
Write-Host "   Long time format: $($currentDateTime.ToLongTimeString())"
Write-Host "   Short time format: $($currentDateTime.ToShortTimeString())"

# Add 10 days to the current date
$newDateTime = $currentDateTime.AddDays(10)

# Display the new date in various formats
Write-Host "New date:"
Write-Host "   Long date format: $($newDateTime.ToLongDateString())"
Write-Host "   Short date format: $($newDateTime.ToShortDateString())"


3. Example 3: Using .NET classes to work with regular expressions

# This script demonstrates how to use .NET classes to work with regular expressions

# Define a regular expression pattern
$pattern = "\d+"

# Define some test strings
$testStrings = @("1234", "abcd", "5678", "!@#$")

foreach ($string in $testStrings) {
    # Test if the string matches the pattern
    if ([System.Text.RegularExpressions.Regex]::IsMatch($string, $pattern)) {
        Write-Host "$string matches pattern."
    } else {
        Write-Host "$string does not match pattern."
    }
}

# Extract all numbers from a string using regular expressions
$stringWithNumbers = "abc123def456ghi789jkl"
$numbersOnlyPattern = "\d+"
$matches = [System.Text.RegularExpressions.Regex]::Matches($stringWithNumbers, $numbersOnlyPattern)
foreach ($match in $matches) {
    Write-Host $match.Value
}
