$emailFrom = "user@host.com"
$emailTo = "destination@host.com"
$subject = "subject"
$body = "message"
$smtpServer = "mail.host.com"
$smtp = new-object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($emailFrom,$emailTo,$subject,$body)

我知道,通过以下命令,我可以找到我所有硬盘上的可用空间：

Get-WmiObject WIN32_logicaldisk | sort -desc freespace | select -first 3 | format-table -autosize deviceid,devicetype,providername,freespace,size,volumename;

当我尝试这样做：

$body = Get-WmiObject WIN32_logicaldisk | sort -desc freespace | select -first 3 | format-table -autosize deviceid,volumename;

但我收到的所有电子邮件都是以下内容：

Microsoft.PowerShell.Commands.Internal.Format.FormatStartData Microsoft.PowerShell.Commands.Internal.Format.GroupStartData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData 
Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.GroupEndData Microsoft.PowerShell.Commands.Internal.Format.FormatEndData

如何使用powershell通过电子邮件获取我的免费空间？
