PowerShell - String Operations

You have a string $data = " red; green ; light blue ; yellow ". How do you split it into an array of clean (trimmed) color names using PowerShell?

A$data.Split(';') | ForEach-Object { $_.Trim() }

B$data.Replace(' ', '').Split(';')

C$data.Split(';').Trim()

D$data.Trim().Split(';')

Step-by-Step Solution

Solution:

Step 1: Split string by semicolon
Use $data.Split(';') to get array: [" red", " green ", " light blue ", " yellow "] with spaces.
Step 2: Trim spaces from each element
Pipe to ForEach-Object with .Trim() to remove spaces from each color name.
Step 3: Check other options
The option $data.Split(';').Trim() tries to call .Trim() on the array (invalid). The option $data.Replace(' ', '').Split(';') removes all spaces, merging multi-word colors like "light blue" into "lightblue" (wrong). The option $data.Trim().Split(';') trims only ends of the whole string.
Final Answer:
$data.Split(';') | ForEach-Object { $_.Trim() } -> Option A
Quick Check:
Split then trim each element = clean array [OK]

Quick Trick: Split first, then trim each part separately [OK]
