HTML电子邮件中的PowerShell显示表

Question

好吧,这可能已经得到了解答,但我是新手并且正在努力学习,所以我想我不会"得到"它.我有一个包含信息表的变量(我从SQL查询中获取).我可以将变量输出到屏幕并查看表格,但是当我尝试在正文中构建HTML电子邮件时,它会出现乱码.

这是代码:

# This code sets up the HTML table in a more friendly format
$style = "<style>BODY{font-family: Arial; font-size: 10pt;}"
$style = $style + "TABLE{border: 1px solid black; border-collapse: collapse;}"
$style = $style + "TH{border: 1px solid black; background: #dddddd; padding: 5px; }"
$style = $style + "TD{border: 1px solid black; padding: 5px; }"
$style = $style + "</style>"

# This code defines the search string in the IssueTrak database tables
$SQLServer = "Blah"
$SQLDBName = "Blah"
$SQLUsername = "Blah"
$SQLPassword = "Blah"
$SQLQuery = "SELECT u.FirstName,u.LastName,u.EMail,COUNT(UserID) as Count
        FROM dbo.Issues i with(nolock)
        JOIN DBO.Users u with(nolock) on u.UserID = i.NextActionBy
        where i.Status='Open'
        group by u.FirstName,u.LastName,u.EMail
        order by Count(*) desc"

# This code connects to the SQL server and retrieves the data
$SQLConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; uid = $SQLUsername; pwd = $SQLPassword"

$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection

$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd

$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()

# This code outputs the retrieved data
$DataSet.Tables | Format-Table -Auto

# This code emails a report regarding the results of the retrieved data
$smtpServer = "Blah"
$smtpFrom = "Blah"
$smtpTo = "Blah"
$messageSubject = "IssueTrak Open Issues By Next Action Report"
$message = New-Object System.Net.Mail.MailMessage $smtpfrom, $smtpto
$message.Subject = $messageSubject
$message.IsBodyHTML = $true
$message.Body = "Here is a listing of open issues in IssueTrak, sorted by Next Action.<br><br>"
$message.Body = $message.Body + $html

$smtp = New-Object Net.Mail.SmtpClient($smtpServer)
$smtp.Send($message)

屏幕上的输出如下所示:

35

FirstName   LastName   EMail                                Count
---------   --------   -----                                -----
John        Doe        John.Doe@blah.com                       51
Jane        Doe        Jane.Doe@blah.com                       20

...但是电子邮件正文如下:

Here is a listing of open issues in IssueTrak, sorted by Next Action.

Microsoft.PowerShell.Commands.Internal.Format.FormatStartData Microsoft.PowerShell.Commands.Internal.Format.GroupStartData

Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData 

...等等.我究竟做错了什么？

Answer 1

这是我如何做到的:

# Create a DataTable
$table = New-Object system.Data.DataTable "TestTable"
$col1 = New-Object system.Data.DataColumn Name,([string])
$col2 = New-Object system.Data.DataColumn Dept,([string])
$table.columns.add($col1)
$table.columns.add($col2)

# Add content to the DataTable
$row = $table.NewRow()
$row.Name = "John"
$row.Dept = "Physics"
$table.Rows.Add($row)
$row = $table.NewRow()
$row.Name = "Susan"
$row.Dept = "English"
$table.Rows.Add($row)

# Create an HTML version of the DataTable
$html = "<table><tr><td>Name</td><td>Dept</td></tr>"
foreach ($row in $table.Rows)
{ 
    $html += "<tr><td>" + $row[0] + "</td><td>" + $row[1] + "</td></tr>"
}
$html += "</table>"

# Send the email
$smtpserver = "smtpserver.domain.com"
$from = "user@domain.com"
$to = "user@domain.com"
$subject = "test"
$body = "Hi there,<br />Here is a table:<br /><br />" + $html
Send-MailMessage -smtpserver $smtpserver -from $from -to $to -subject $subject -body $body -bodyashtml

Answer 2

我认为这是一个更好的解决方案（参见参考文献 1）

$DataSet.Tables[0] |select * -ExcludeProperty RowError, RowState, HasErrors, Name, Table, ItemArray | ConvertTo-Html 

使用 ExcludeProperty 我们可以从我们的表中排除嘈杂的列，而无需特别指定我们想要的列
