How to terminate variable expansion to create a string in Powershell

Question

How do I tell powershell the end of a variable to be expanded into a string when it sits next to other alphabetic characters?

$StringToAdd = "iss"
$CompeteString = "Miss$StringToAddippi"

Thanks!

Answer 1

Use curly braces, { and }, to delimit the variable expansion. For example:

PS C:\> $StringToAdd = "iss"
PS C:\> $CompeteString = "Miss${StringToAdd}ippi"
PS C:\> $CompeteString
Mississippi

Answer 2

You can use $()

PS C:\> $StringToAdd = "iss"
PS C:\> $CompeteString = "Miss$($StringToAdd)ippi"
PS C:\> $CompeteString
Mississippi

The sub-expression operator for double-quoted strings is described here. Whatever is in the brackets should be evaluated first. This can be a variable or even an expression.

PS C:\> $CompeteString = "Miss$($StringToAdd.length * 2)ippi"
PS C:\> $CompeteString
Miss6ippi
