Question

我已经有一个Powershell脚本执行sql查询并格式化结果并通过电子邮件将其发送到指定为脚本命令行arg的电子邮件地址。如果需要，它还会附加结果的CSV。

我正在尝试为powershell脚本构建一个web前端，而不是cmd行使用的粉丝。我在ASP网页上使用C＃。从命令行运行脚本工作正常，但是当我从网页运行脚本时，我收到TSQL错误。我调试了脚本，知道它正在运行带有正确参数的脚本，但是当它遇到Invoke-SqlCmd命令行开关时失败。我没有在stackoverflow或谷歌的其他部分看到任何错误。建议？

PowerShell脚本：

$serverName="server"
$dbName="perfmon"

$mailServer="exchange"
$mailUser="testUser"
$mailPass="pass"

$workingPath="D:\scripts"
$scriptFile=$workingPath + "\queryStats.sql"
$tmpSql=$workingPath + "\tmpSql.sql"
$timeout="600"

$mailPass=ConvertTo-SecureString $mailPass -AsPlainText -Force
$cred=New-Object System.Management.Automation.PSCredential($mailUser,$mailPass)


$fromEmail="perfmonDB@test"
$toEmail=$args[0]
$getCSV=$args[1]


#add SQL snap ins
Add-PSSnapin SqlServerProviderSnapin100
Add-PSSnapin SqlServerCmdletSnapin100

$sqlCommand= "Invoke-Sqlcmd -ServerInstance $serverName -Database $dbName -InputFile $tmpSql -QueryTimeout $timeout"
echo "$sqlCommand" >> $workingPath\log.txt
$results=Invoke-Expression $sqlCommand

$emailResults = $results | format-table| Out-String
$emailResults = $results | convertto-html -property MachineName, InstanceName, CounterName, Average, Minimum, Maximum| Out-String
if($getCSV -eq "Yes")
{
  $csvResults = $results | Convertto-csv
  $results | Export-Csv $workingPath\results.csv
  Send-MailMessage -To ($toEmail) -Subject "Perfmon Query Results" –From ($fromEmail) -Body $emailResults -Credential $cred -SmtpServer ($mailServer) -BodyAsHtml -Attachments $workingPath\results.csv
}
else {
Send-MailMessage -To ($toEmail) -Subject "Perfmon Query Results" –From ($fromEmail) -Body $emailResults -Credential $cred -SmtpServer ($mailServer) -BodyAsHtml

}
Remove-item $workingPath\tmpSql.sql
Remove-item $workingPath\results.csv

无法调用从c＃调用SQL查询的powershell脚本
