Question

我有一段代码比较两个值，如果条件满足，它会发送一封电子邮件。但它不起作用，感谢帮助。

代码：

$filesize =  Get-ChildItem $filename | Select-Object Length | Format-Wide
$filesize
$num=1265
$num
if("$filesize" -gt "$num")
{

$SMTPServer = "10.20.19.94"

$SMTPPort = 25

$username = "vcenter@somosadc.com"



#Define the receiver of the report

$to = "jeevan.m2@hcl.com"

$subject = "VM Snapshot Report"

$body = "VM Snapshot Report"

$attachment = new-object Net.Mail.Attachment($filename)

$message = New-Object System.Net.Mail.MailMessage

$message.subject = $subject

$message.body = $body

$message.to.add($to)

$message.from = $username

$message.attachments.add($attachment)



$smtp = New-Object System.Net.Mail.SmtpClient($SMTPServer, $SMTPPort);

$smtp.EnableSSL = $false

#$smtp.Credentials = New-Object System.Net.NetworkCredential($Username, $Password);

$smtp.send($message)

write-host "Mail Sent"
}

输出：

1262                                                                                                                                 
1265
Mail Sent

如果$ filesize = 1262小于$ num = 1265，为什么会发送电子邮件。它杀了我。

Answer 1

因为您没有比较两个数字，所以您要比较两个字符串。

从第一个管道中删除Format-Wide命令，并删除if条件中参数周围的引号：

$filesize = Get-ChildItem $filename | Select-Object Length
$num = 1265
if($filesize.Length -gt $num) {
  <# ... #>
}

Power Shell：如果条件变量比较不起作用
