send-mailmessage用System.String []替换html样式标签。

Question

I am trying to use send-mailmessage to send an email in powershell (v2).

I run a MySQL Query, and convert it to html as follows:

$htmlbody = $mysqlresult | `
ConvertTo-Html -property field1, `
field2, `
field3 `
-pre "<style>table{border: 3px solid #000000;}</style>"

I then send an email as:

Send-MailMessage -to "$ToAddress" `
    -From "$FromAddress" `
    -Subject "Subject Line" `
    -BodyasHtml "$htmlbody" `
    -SmtpServer "$SMTP"   

The email sends, and I get my email with the data in a table. But the ... section gets replaced with System.String[]

As far as I can tell, there's no 'funny' characters in there. Can anyone explain why this is?

Select your properties before piping the objects into ConvertTo-Html :

$htmlbody = $mysqlresult |
            select field1, field2, field3 |
            ConvertTo-Html -Pre '<style>...</style>'

Depending on what datatype of the fields actually have you may need to mangle string arrays into strings first, for instance via calculated properties . Example:

$htmlbody = $mysqlresult |
            select field1, field2, @{n='field3';e={$_.field3 -join ' '}} |
            ConvertTo-Html -Pre '<style>...</style>'
