Variables 发送邮件失败，因为缺少附件（变量出错）

我正在用

Send MailMessage

有些文件存在，有些文件不存在，因此如果其中一个文件丢失，

Send MailMessage

将失败

如果文件丢失，是否有办法执行

测试路径

并清理

$attachments

我的代码：

$Attachments = "$longlist_file","$PingList_File","$quicklist_file", `
  "$nConf_import_host_file","$nConf_import_service_file", `
  "$nconf_export_host_file","$nconf_export_service_file"

# Sending mail
send-mailmessage -to $ToAddress -from $FromAddress -smtpserver $SMTPServer `
  -subject $MessageSubject -Body $MessageBody -Attachments $Attachments

---

创建仅包含现有文件的新列表：

$realFiles = $Attachments | ? {Test-Path -Path $_}

然后发送

send-mailmessage -to $ToAddress -from $FromAddress -smtpserver $SMTPServer -subject $MessageSubject -Body $MessageBody -Attachments $realFiles

$realFiles = $Attachments | ? {Test-Path -Path $_}

send-mailmessage -to $ToAddress -from $FromAddress -smtpserver $SMTPServer -subject $MessageSubject -Body $MessageBody -Attachments $realFiles

像这样的事情应该可以做到：

$Attachments = @("$longlist_file","$PingList_File","$quicklist_file","$nConf_import_host_file","$nConf_import_service_file","$nconf_export_host_file","$nconf_export_service_file")
$TestedAttachments = @()
foreach($file in $Attachments)
{
    try
    {
        $file = get-content -path $file
        write-host "File $($file) exists, adding to tested list"
        $TestedAttachments += $file
    }
    catch[system. exception]
    {
        write-host "File $(file) was not found."
    }
}
send-mailmessage -to $ToAddress -from $FromAddress -smtpserver $SMTPServer -subject $MessageSubject -Body $MessageBody -Attachments $TestedAttachments

问候

    }
}
send-mailmessage -to $ToAddress -from $FromAddress -smtpserver $SMTPServer -subject $MessageSubject -Body $MessageBody -Attachments $TestedAttachments

问候 阿卡斯可能

$Attachments = $longlist_file","$PingList_File","$quicklist_file", `
  "$nConf_import_host_file", "$nConf_import_service_file", `
  "$nconf_export_host_file", "$nconf_export_service_file" `
  | Where-Object { Test-Path $_ }

大概

$Attachments = $longlist_file","$PingList_File","$quicklist_file", `
  "$nConf_import_host_file", "$nConf_import_service_file", `
  "$nconf_export_host_file", "$nconf_export_service_file" `
  | Where-Object { Test-Path $_ }

杰出的谢谢大家的帮助。我投票选择这个作为答案，因为它是如此的简短和紧凑。太棒了！谢谢大家的帮助。我之所以选择这个作为答案，是因为它是如此的简短和紧凑。当你只想测试文件是否存在时，阅读文件是不必要的。您可以使用

Test Path

cmdlet来验证文件是否存在。如果只想测试文件是否存在，则无需读取该文件。您可以使用

测试路径
