How to split a string content into an array of str

问题:

I have a string that has email addresses separated by semi-colon:

$address = "[e-mail]; [e-mail]; [e-mail]"

How can I split this into an array of strings that would result as the following?

[string[]]$recipients = "[e-mail]", "[e-mail]", "[e-mail]"

回答1:

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

回答2:

[string[]]$recipients = $address.Split('; ',[System.StringSplitOptions]::RemoveEmptyEntries)

回答3:

Remove the spaces from the original string and split on semicolon

$address = "[e-mail]; [e-mail]; [e-mail]"
$addresses = $address.replace(' ','').split(';')

Or all in one line:

$addresses = "[e-mail]; [e-mail]; [e-mail]".replace(' ','').split(';')

$addresses becomes:

@('[e-mail]','[e-mail]','[e-mail]')
