Question

Im trying to join a number of elements of an array into a string using this;

$a = 'h','e','l','l','o' $b = [string]::join('', $a[0,1,2,3]) 

But I get a ‘Missing ‘)’ in method call’ error. The join documentation only mentions joining all the elements of an array, not elements at specific indexes. Can this be done?

Cheers

Andy

Answer 1

Wrap the content of ‘$a[0,1,2,3]’ with ‘$()’ or ‘()’

PS> [string]::join('', $($a[0,1,2,3])) hell PS> [string]::join('', ($a[0,1,2,3])) hell 

— Or —

you can use range operator ‘..’

PS> [string]::join('', $a[0..3]) hell
