In PowerShell 5.0 and higher, an object instance may be created using the new static method:

$stringBuilder = [System.Text.StringBuilder]::new() 

For earlier versions of PowerShell, the object instance may be created using the following syntax:

$stringBuilder = New-Object System.Text.StringBuilder 

PowerShell has added the static method (discussed later in this chapter); it can be used if required, but it isn't documented on the MSDN page for StringBuilder.

Once an instance of StringBuilder has been created, it can be viewed:

PS> $stringBuilder = New-Object System.Text.StringBuilder
PS> $stringBuilder

The StringBuilder object has a number of other constructors. These are used to adjust the initial state of the instance.
