PowerShell outputting array items when interpolating within double quotes

by

So when you are using interpolation, by default it interpolates just the next variable in toto. So when you do this:

"$test[0]"

It sees the $test as the next variable, it realizes that this is an array and that it has no good way to display an array, so it decides it can’t interpolate and just displays the string as a string. The solution is to explicitly tell PowerShell where the bit to interpolate starts and where it stops:

"$($test[0])"

Note that this behavior is one of my main reasons for using formatted strings instead of relying on interpolation:

"{0}" -f $test[0]
