Power Shell: If condition variable comparison not working - powershell

Question

I have a piece of code comparing two values, and if the condition is satisfied it sends out an email. But it is not working, help is appreciated.
code:
$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"
}
output:
1262
1265
Mail Sent
Why is it sending email if $filesize=1262 is less than $num=1265. It is killing me.

Answer 1

Because you're not comparing two numbers, you're comparing two strings.
Remove the Format-Wide command from the first pipeline, and remove the quotes around the arguments in your if condition:
$filesize = Get-ChildItem $filename | Select-Object Length
$num = 1265
if($filesize.Length -gt $num) {
<# ... #>
}
