我正在尝试通过命令行执行以下命令
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe Send-MailMessage -from "mail.me" -to "mail.me" -Subject "PS test !" -Body "Hi this is a power shell mail test" -SmtpServer "mail.domain.com"
但是我收到以下错误:
Send-MailMessage : A positional parameter cannot be found that accepts arguement « test ».
Au niveau de ligne : 1 Caractère : 17

例如:
$a1 = @(1,2,3,4,5,6,7,8)
$a2 = @(1,2,3)
