Those Annoying thing in Powershell

Powershell v2.0 has a cmdlet that allows you to send an email



    Sends an e-mail message.

    Send-MailMessage [-To] <string[]> [-Subject] <string> -From <string> [[-Body] <string>] [[-SmtpServer] <string>] [-Attachments <string[
    ]>] [-Bcc <string[]>] [-BodyAsHtml] [-Cc <string[]>] [-Credential <PSCredential>] [-DeliveryNotificationOption {None | OnSuccess | OnFa
    ilure | Delay | Never}] [-Encoding <Encoding>] [-Priority {Normal | Low | High}] [-UseSsl] [<CommonParameters>]

    The Send-MailMessage cmdlet sends an e-mail message from within Windows PowerShell.

    Online version:

    To see the examples, type: "get-help Send-MailMessage -examples".
    For more information, type: "get-help Send-MailMessage -detailed".
    For technical information, type: "get-help Send-MailMessage -full".

Ok so today I has a collection that I had stored in a variable

[12:39:03] ~> $myvar | gm 

   TypeName: Selected.System.Management.Automation.PSCustomObject

And when I tried this:

[12:40:18] ~> Send-MailMessage –From "maishsk@maishsk.local" -To "maishsk@maishsk.local" -Subject "test" -SmtpServer smtp.maishsk.local -Body ($myvar)

I was presented with this:

Send-MailMessage : Cannot convert 'System.Object[]' to the type 'System.String' required by parameter 'Body'. Specified method is not supported.
At line:1 char:114
+ Send-MailMessage –From “maishsk@maishsk.local” –To “maishsk@maishsk.local” -Subject "test" -SmtpServer smtp.maishsk.local -Body <<<<  ($myvar)
    + CategoryInfo          : InvalidArgument: (:) [Send-MailMessage], ParameterBindingException
    + FullyQualifiedErrorId : CannotConvertArgument,Microsoft.PowerShell.Commands.SendMailMessage

Thanks to my trusted friend Shay Levy (who always has the time to help out and is never tired of my questions - “I hope…” ) he explained to me why this was happening.

The object that is expected in the Body parameter is a TypeName: System.String object. I also could have seen that if I had looked properly in the help of the cmdllet -- [[-Body] <string>] --

So the solution was very simple. Out-String

[12:49:11] ~> $myvar | Out-String | gm 

   TypeName: System.String

And with that it was not a problem to send the mail

[12:50:18] ~> Send-MailMessage –From "maishsk@maishsk.local" -To "maishsk@maishsk.local" -Subject "test" -SmtpServer smtp.maishsk.local -Body ( $myvar | out-string )

Is it not wonderful that you learn something new every day!

Back to work….

Small Edit:

<------ RANT -------->

Just clarify this is not a Powershell problem – it does exactly what it is supposed to.
Tthe annoying part is that it takes a while to figure out the problem is.
