好的，这可能已经回答了，但我是新手并且正在努力学习，所以我想我没有“得到”它。我有一个包含信息表的变量（我从 SQL 查询中得到它）。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使用它构建 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
...但电子邮件正文如下所示：
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？
