powershell - Count occurence of data in array

Question

I have an array like this:

OptiPlex 790
Precision WorkStation T7500
Precision WorkStation T7400
Precision T1500
Precision WorkStation T3500
CELSIUS R650
VMware Virtual Platform
Precision T1500
OptiPlex GX620

I want to get the count of array and will add that in new array.

Element:Count
OptiPlex 790 1 
Precision WorkStation T7500 1 
Precision WorkStation T7500 1

I want to store this value in new array. So, i will use it later/somewhere else.

$array = @()
for ($i=1; $i -le $rowMax-1; $i++) {
    $Model = $sheet.Cells.Item($rowModel+$i, $colModel).text
    Write-Host ("I am reading data on row: " + $i)
    $array += $Model
}

$array | Group

At the moment above script is working fine but I don't know how I can add this data to new array.

Answer 1

There is a Group-Object cmdlet which you can use for that:

$array | group | select Name, Count

Output:

Name                        Count
