Powershell Select-Object from array not working

I am trying to seperate values in an array so i can pass them to another function.

Am using the select-Object function within a for loop to go through each line and separate the timestamp and value fields.

However, it doesn't matter what i do the below code only displays the first select-object variable for each line. The second select-object command doesn't seem to work as my output is a blank line for each of the 6 rows.

Any ideas on how to get both values

$ReportData = $SystemStats.get_performance_graph_csv_statistics( (,$Query) )


### Allocate a new encoder and turn the byte array into a string
$ASCII = New-Object -TypeName System.T开发者_开发技巧ext.ASCIIEncoding
$csvdata = $ASCII.GetString($ReportData[0].statistic_data) 

$csv2 = convertFrom-CSV $csvdata


$newarray = $csv2 | Where-Object {$_.utilization -ne "0.0000000000e+00" -and   $_.utilization -ne "nan" }


    for ( $n = 0; $n -lt $newarray.Length; $n++)
    {
       $nTime =  $newarray[$n]
       $nUtil =  $newarray[$n]
       $util = $nUtil | select-object Utilization
       $util
       $tstamp = $nTime | select-object timestamp
       $tstamp

    }

Let me slightly modify the processing code, if it will help.

$csv2 | 
  Where-Object {$_.utilization -ne "0.0000000000e+00" -and   $_.utilization -ne "nan" } |
  Select-Object Utilization,TimeStamp

It will produce somewhat different output, but that should be better for working with. The result are objects with properties Utilization and TimeStamp. You can pass them to the another function as you mention.

Generally it is better to use pipes instead of for loops. You don't need to care about indexes and it works with arrays as well as with scalar values.

If my updated code won't work: is the TimeStamp property really filled with any value?
