String concatenation in PowerShell

Introduction

String concatenation lets you join two or more pieces of text into one. This helps you build messages or combine data easily.

Creating a full name from first and last names.

Building a file path from folder and file names.

Making a sentence from separate words or phrases.

Combining user input with fixed text for messages.

Syntax

PowerShell

$fullString = $string1 + $string2

Use the plus sign (+) to join strings.

You can also use double quotes with variables inside for easy joining.

Examples

Joins two fixed text pieces into one greeting.

PowerShell

$greeting = "Hello, " + "world!"

Joins first and last name with a space in between.

PowerShell

$firstName = "Jane"
$lastName = "Doe"
$fullName = $firstName + " " + $lastName

Uses double quotes to insert variable directly into the string.

PowerShell

$name = "John"
$message = "Welcome, $name!"

Sample Program

This script joins first and last names with a space and prints the full name.

PowerShell

$firstName = "Alice"
$lastName = "Smith"
$fullName = $firstName + " " + $lastName
Write-Output "Full name is: $fullName"

Important Notes

Remember to add spaces manually if you want them between words.

Using double quotes with variables inside is often easier than using + for many parts.

You can join more than two strings by repeating the + operator.

Summary

Use + to join strings simply.

Double quotes allow easy variable insertion.

Add spaces yourself when joining words.
