Powershell Array to Datatable

In Powershell what is the best way to import all array values into a Datatable?  I've created the Datatable with a specific format so I can pass it into a stored procedure.  I'm pulling in some server information from multiple servers and this is getting added to an array object.  The number of columns in both match.  

I thought something along the lines of this might work but it's not.  

$DBStats | ForEach-Object {$dt.ImportRow($_)}

Open in new window


$DBStats is my object array, $dt is my Datatable.

EDIT: I've been able to add to the Datatable now from the array using the below function.  Is there a better way of doing this?  

Function LoadDataTable
{
	PARAM($dt,$DBStats)
	$DBStats | ForEach-Object {
		$row = $dt.NewRow()
		$row.Item('Parent') = $_.Parent.ToString()
		$row.Item('Name') = $_.Name.ToString()
		$row.Item('Size') = $_.Size.ToString()
		$dt.Rows.Add($row)
		}
}

An improvement is not to use foreach-object but foreach, as this performs better on already existing data (versus data created on the fly):
Function LoadDataTable(dt,$DBStats)
{
  foreach ($data in $DBStats)
  {
     $row = $dt.NewRow()
     $row.Item('Parent') = $data.Parent
     $row.Item('Name') = $data.Name
     $row.Item('Size') = $data.Size
     $dt.Rows.Add($row)
  }
}

Open in new window

This could be made more dynamic:
Function LoadDataTable(dt,$DBStats)
{
  $cols = $DBStats | select -first 1 | get-member -MemberType NoteProperty | select -Expand Name
  foreach ($data in $DBStats)
  {
     $row = $dt.NewRow()
     foreach ($col in $cols)  { $row.Item($col) = $data.$col }
     $dt.Rows.Add($row)
  }
}
