how comes row data becomes System.Data.DataRow in stead of value.

Hi all, i already googled this and tried allot but no succes yet. Perhaps i can find help here ? Here it goes:

i dont have to much expirience on powershell, i'm a DBA and i feel that powershel can help me in my daily job !

I need to restart servers via restart-computer  and use a variable as the computer name. This variable comes from a select query on a database.  however i always get " The RPC server is unavailable." I repeated the command and did write-host and found that my variable returns:

System.Data.DataRow

for each record in the database.

this is the code:

$BootRegime= 'TST'
$RebootStatsServer = 'Dbserver01'
$RebootStatsDB = 'Database01'
$SelectQuery = "SELECT server FROM ServerStatus where regime ='$BootRegime'"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlGetListConnection.ConnectionString = "Server=$RebootStatsServer;Database=$RebootStatsDB;Integrated Security=True"
$SqlGetListConnection.open()
$SqlGetListCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlGetlistCmd.CommandText = $SelectQuery
$SqlGetListCmd.Connection = $SqlGetListConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlgetlistCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$srv=$dataset.tables[0]
Foreach ($server in $srv)
{
write-host "$server"
}
$SqlGetListConnection.close()

ty in advance!
