Powershell在线发送“if”用于send-mailmessage

Question

如果有要传递的变量，PowerShell中是否可以在cmdlet调用中添加参数？

E.g。

Send-MailMessage -To $recipients (if($copy -ne "") -cc $copy) ....

不是你上面写的方式，但你可以splat the parameters，用条件构建哈希，这样你只需要调用一次send-mailmessage。我几个月前写的一个脚本的例子：

#Set up default/standard/common parameters
$MailParams = @{
"Subject"="This is my subject";
"BodyAsHtml" = $true;
"From" = $MailFrom;
"To" = $MailTo;
"SmtpServer" = $SMTPServer;
};

#On the last day of the month, attach a logfile.
if ((Get-Date).AddDays(1).Day -eq 1) {
$attachment = $LogFilePath;
$ReportContent = "Full log for the the preceding month is attached.<br><br>" + $ReportContent;
$MailParams.Add("Attachments",$attachment);
}

send-mailmessage @MailParms

所以在你的情况下，它将是：

$MailParams = @{
"Subject"="This is my subject";
"From" = $MailFrom;
"To" = $recipients;
"SmtpServer" = $SMTPServer;
};

if (($copy -ne [string]::empty) -and ($copy -ne $null)) {
$MailParms.Add("CC",$copy);
}

send-mailmessage @MailParms
