How do I convert an array object to a string in PowerShell?

Question

How can I convert an array object to string?

I tried:

$a = \"This\", \"Is\", \"a\", \"cat\"
[system.String]::J         


        

Answer 1

$a = 'This', 'Is', 'a', 'cat'

Using double quotes (and optionally use the separator $ofs)

# This Is a cat
"$a"

# This-Is-a-cat
$ofs = '-' # after this all casts work this way until $ofs changes!
"$a"

Using operator join

# This-Is-a-cat
$a -join '-'

# ThisIsacat
-join $a

Using conversion to [string]

# This Is a cat
[string]$a

# This-Is-a-cat
$ofs = '-'
[string]$a
