Question

我有这个从powershell查询SQL：

PARAM([String] $env_code, [String] $db_server)

$connectionString = "ConnectTheShizz"
$connection = new-object system.data.SqlClient.SQLConnection($connectionString)
$sqlCommand = "SELECT Yada FROM YadaYada"

$command = new-object system.data.sqlclient.sqlcommand($sqlCommand,$connection)
$connection.Open()

$adapter = New-Object System.Data.sqlclient.sqlDataAdapter $command
$dataset = New-Object System.Data.DataSet
$adapter.Fill($dataSet) | Out-Null

$connection.Close()

$strStuff = $DataSet.Tables[0].rows| ft -HideTableHeaders

我不确定$ strStuff是什么（它是什么DataType或者其他什么）。如果我只是将它打印到控制台，我会得到一个看起来像一个整数的数组（虽然在数据库中，这些是字符串，所以我不确定这是否是他们回来的那样）：

但如果我试图让它们成为字符串：

$strStuff | ForEach-Object {$_.ToString()}
Microsoft.PowerShell.Commands.Internal.Format.FormatStartData
Microsoft.PowerShell.Commands.Internal.Format.GroupStartData
Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData
Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData
...

如果我只是假设他们是字符串，并尝试继续前进，我就明白了：

$strCusips -join ','
Microsoft.PowerShell.Commands.Internal.Format.FormatStartData,Microsoft.PowerShell.Commands.Internal.Format.GroupStartData,Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData,Microsoft.PowerShell.Commands.Internal.Format.FormatEntryData,...

编辑：

为了更清楚，这就是我所拥有的：

这就是我想要的（一个以逗号分隔的单个字符串）：

0003128,0005588,0016308,0021216,...

编辑2：

使用.GetType()我明白了：

IsPublic IsSerial Name                                     BaseType            
-------- -------- ----                                     --------            
True     True     Object[]                                 System.Array

| Get-Member这样做：
