Powershell脚本检查文件的修改日期，如果更改则发送电子邮件

# 设置文件路径和电子邮件相关信息
$filePath = "C:\path\to\file.txt"
$senderEmail = "sender@example.com"
$receiverEmail = "receiver@example.com"
$smtpServer = "smtp.example.com"

# 获取文件的最后修改日期
$file = Get-Item $filePath
$lastModified = $file.LastWriteTime

# 获取当前日期和时间
$currentDateTime = Get-Date

# 比较文件的最后修改日期和当前日期
if ($lastModified -gt $currentDateTime) {
    # 创建电子邮件对象
    $email = New-Object System.Net.Mail.MailMessage
    $email.From = $senderEmail
    $email.To.Add($receiverEmail)
    $email.Subject = "文件已修改"
    $email.Body = "文件 $filePath 已于 $lastModified 修改。"

    # 创建SMTP客户端对象并发送电子邮件
    $smtpClient = New-Object System.Net.Mail.SmtpClient($smtpServer)
    $smtpClient.Send($email)
}
