PowerShell Concatenate String 

PowerShell strings can be one of the most common data types: to display messages, ask for input, or deliver data to files.

In this article, you will discover that strings are useful for more than just reading and presenting. You can also concatenate them for various purposes. So let’s have a look at PowerShell concatenate String.

What Is PowerShell Concatenate String?

Strings are created by surrounding a group of characters in single or double quotations. 

The String object represents the String’s final value. The [System.String] type [String] is the type of the.NET object known as the String object.

Therefore, string concatenation turns several independent string objects into a single string by connecting two or more strings. 

PowerShell has a variety of techniques for concatenating strings. So considering how you intend to use string concatenation will determine which approach suits you because each is unique.

PowerShell Concatenate String

Use + Operator To Concatenate String

The + operator is the simplest technique to concatenate strings. The + operator can only be used for concatenation when all elements are strings. If the + operator is used on two or more variables of the integer type, the script will mathematically process the statement.

To do this, run the script to inspect the output after pasting the code into the Script tab of your PowerShell ISE. The quantity of strings varies, nevertheless, depending on the need.

Example: 

$concatString = $str1 + $str2 + $str3

Write-Output $concatString

Output:

First Second Third

Use Separators To Concatenate String

You may utilize separators like commas (,) instead of the + operator when concatenating texts. Also, always wrap your string values in double quotations to avoid the variable interpreting your split string values as a listed property. 

Example: 

$concatString = “$str1 , $str2 , $str3”

Write-Output $concatString

Output:

First, Second, Third

Use String Substitution To Concatenate String 

As an alternative, string substitution can achieve another concatenation method. This technique will also function for string concatenation with various data types.

Example: 

$int1 = 0

$concatString = “$($int1) , $($str2)”

Write-Output $concatString

Output:

0, Second

Use -join Operator To Concatenate String 

There are two ways to combine many strings using the -Join operator.

The array of strings you wish to concatenate comes after the -Join command, which is the first method to utilize. There is no opportunity to provide a delimiter when using the -Join operator. 

There will be no space between any of the strings in the matrix since they are all glued together.

Example: -Join <String[ ]>

Specifying the delimiter used is the second way to utilize the -Join operator. The collection of strings will be combined, but each String will have the designated delimiter character placed between it.

Example: <String[ ]> -Join <Delimiter>

Use -f Operator to Concatenate String

The -f operator is another tool for string concatenation. String variables are used as parameters on a pre-built given string when using the -f operator.

The number included in the curly brackets indicates the String’s index. The index of the first String to be considered is 0, the index of the second String is 1, etc. 

Example: 

$concatString = “{0}.{1}.{2}.” -f $str1,$str2,$str3

Write-Output $concatString

First.Second.Third

Use Concat To Concatenate String

Finally, the Concat gives another string concatenation method and what is special about this is that there will be no limitation on the amount of chosen strings to concatenate. 

Example: 

$s1= “first string::”

$s2= “second string::”

$s3= “third string::”

$s4= “fourth string.”

$res=[string]::Concat($s1, $s2, $s3, $s4)

$res

Output: 

PS C: \scripts> .con4.ps1

first string: :second string: : third string: fourth string.

FAQs

Is It Difficult To Learn PowerShell?

Despite being an incredibly useful and strong technology, Windows PowerShell may be challenging to grasp. Several little details can make PowerShell behave in entirely unexpected ways. 

Not to mention that the platform usually has new cmdlets. So yes, it can be quite challenging to learn and master PowerShell. 

What Does += Mean in PowerShell?

The assignment operator += adds the supplied value to the current value of a variable or increases its value. The result relies on the variable’s String or numeric type and whether it has a specific number (a scalar) or many values (a collection).

What Does $_ Mean in PowerShell?

The “$_” is the pipeline parameter in PowerShell. The automatic variable “$PSItem” in PowerShell is an alias for the “$_” variable. It may be used in various ways, including filtering items and making references to certain objects.
