Count the number of columns in an array with PowerShell - powershell

Question

I have the following code:
$array = Get-Process
Now, I want to count the number of columns. I have tried:
$array.Columns.Count
$array.Columns
And all without luck.
What should I do to get the correct number of columns? That should be 8.

I have modified the code to:
$Processes = #(Get-Process | Select-Object -Property Name, Description, ProductVersion, #{Name="Application";Expression={$_.Description + " " + $_.ProductVersion}},#{Name="Executable";Expression={(($_."Path").split("\"))[-1]}} |Where {$_.Executable})
$Array = #()
$Record = [ordered] #{"Name" = "";
"Application" = ""}
ForEach ($ProcesName in $Processes)
{
$Record."Name" = $ProcesName.Name
$Record."Application" = $ProcesName.Application
$objRecord = New-Object PSObject -Property $Record
$Array += $objRecord
}
Clear-Host
Write-Host "Number of columns: $($Array.Column.Count)"
Write-Host "Number rows: $($Array.Count)"
The result is the same: both the column and row are the same. And that is not correct. I want to use the technique in a new script with much more columns.

Answer 1

$array is an array of objects of type System.Diagnostics.Process. There aren't columns as such. The objects have properties which you may choose to display in columns using $array | ft or as a list $array | fl *. You can count the properties like this:
$array | Get-Member -MemberType Property | measure
If you'd like the answer to be 8 then you can do this:
$array | select Handles, NPM, PM, WS, CPU, Id, SI, Name | Get-Member -MemberType NoteProperty | measure
