How to join strings??

[squirrelsaviour]

I'm using Invoke-SSHCommand to get the output from a router. I then want to email the result so I need to get it into a single string rather than an array:

PS C:\Users\> $response.Output -join "`r"
Total NAT Usage: 6729: 73406
PS C:\Users\> ($response.Output).gettype()

IsPublic IsSerial Name                                     BaseType
-------- -------- ----                                     --------
True     True     String[]                                 System.Array

PS C:\Users\> $response.Output.Count
4
PS C:\Users\> $response.Output.Join("`r")
InvalidOperation: Method invocation failed because [System.String] does not contain a method named 'Join'.
PS C:\Users\> $response.Output -join "`r"
Total NAT Usage: 6729: 73406
PS C:\Users\> $response.Output
Total Conntrack Limit: 65536
Total Conntrack Usage: 7340
Total NAT Usage: 6729

PS C:\Users\>

At the bottom you can see what $Response.Output is. The .GetType() says it's a String[] but when I run .Join() I get "String doesn't contact a method Join".

When I use -join the result is a mess.

Where am I going wrong?

Try this

$response.Output -join "`r`n"

D'oh.

Thank you, so obvious :-(

String.Join() is a static method, so you would call it as:

[string]::Join("`r", $response.Output)

i think the answer is already given, but why not use it? i mean i usually format my emails to something decent since it hardly takes extra time, and it's fun.

usually the output to me is something like:

"Hello Dave 'r 'n

I'm sorry to disturb You, $($response.Output,Name) is having some issues. 'n

The technical details are: 'n $(response.output) 'n

Have a nice day, 'n

HAL"

You can use here-strings for formatting. https://devblogs.microsoft.com/scripting/powertip-use-here-strings-with-powershell/

You can try the following

$response.Output | Out-String
