Store results of split function in variables - shell

Question

I have files in a directory like below:
first-file-name
2nd-file-name
3rd-file-name
.
.
n-file-name
I need to store each portion of file name in a separate variable because I want to insert these values in separate columns of table.
For this, I used the below script to get the each portion of a file name:
$var1=$item.BaseName.Split("-",3)[0]---------first
$var2=$item.BaseName.Split("-",3)[1]---------file
$var3=$item.BaseName.Split("-",3)[2]---------name
and can save these values in a variable. But the question is how can I do this for all files, if I use foreach loop then the variable values will be overwritten???
foreach(item in $items)
{
$var1=$item.BaseName.Split("-",3)[0]---------first
$var2=$item.BaseName.Split("-",3)[1]---------file
$var3=$item.BaseName.Split("-",3)[2]---------name
}
Here, in $items I got the file path using get-childitem.

Answer 1

I would create a PsCustomObject with the three parts:
$parts = $items | ForEach-Object {
[PsCustomObject]#{
FirstPart = $item.BaseName.Split("-",3)[0]
SecondPart = $item.BaseName.Split("-",3)[1]
ThirdPart = $item.BaseName.Split("-",3)[2]
}
}
now $parts is an array of these objects so you can access them using e. g.
$parts[0].FirstPart
