How to enter get-childitem in to a string - powershell

Question

I am tring to create a script that will output the name of .txt files via for loop that counts the number of files and creates an option to open .txt file from just one click.
$s = (Get-ChildItem -Path C:\*.txt -Name | Measure-Object -Line).Lines
for($i=0; $1 -gt 5 ;$i++)
{
$c = [string[]](Get-ChildItem -Path C:\*.txt -Name)
[void] $objListBox.Items.Add('$i')
Write-Output $c
}
I am stuck with Get-childitem like in $c to get the list of file names into a variable so i can split or get the line for user option.
Thanks in advance

i am not sure what exactly you want from the script,
but here is my approach to set the items in $objListBox
$txtFiles=Get-ChildItem -Path C:\stackoverflow -Recurse -Filter *.txt
#Option 1 FullPath to Items
$txtFiles.fullname | ForEach-Object { $objListBox.Items.Add($_) }
#Option 2 Just the Name to Items
$txtFiles.name | ForEach-Object { $objListBox.Items.Add($_) }
#Option 3 Just the Name without Extentension to Items
$txtFiles.basename | ForEach-Object { $objListBox.Items.Add($_) }
#Count for All Files
$txtFiles.Count

You can use the .ToString
method to convert any given object to a string. If you want $c to be a string, the code you are looking for would look something like this:
$c = (Get-ChildItem -Path C:\*.txt -Name).ToString

Made a form for you that is created with a dynamic size and additionally a scrollbar if there is no space left. buttons that start the txt file and close the form. More comments in the code.
$basePath = "C:\"
$SearchString = Join-Path $basePath "*.txt"
$filenames = #(Get-ChildItem -Path $SearchString -Name | Sort)
$count = $filenames.count
#All you need for System.Windows.Forms to work
Add-Type -AssemblyName System.Windows.Forms
# Variables for generating size
$ButtonHeight = 35
$ButtonWidth = 450
$WindowTitle = "Choose a file"
$BottomSpace = $StartHeight = 10
$LeftSpace = $RightSpace = 30
$CurrentHeight = $Startheight
$FormHeight = 60 + $BottomSpace + $StartHeight + $ButtonHeight * $count
$FormWidth = 20 + $LeftSpace + $RightSpace + $ButtonWidth
# Create the form
$form = New-Object System.Windows.Forms.Form
$form.Text = $WindowTitle
$form.Size = New-Object System.Drawing.Size($FormWidth,$FormHeight)
$form.FormBorderStyle = "Fixed3d" # Sizeable: User may change size - Fixed3d: User may not change size
$form.StartPosition = "CenterScreen"
$Form.AutoScroll = $True # Scrollbars when you need it
$form.Topmost = $true #always on top
$form.MaximizeBox = $false #Allows to maximize window
# Generate the buttons in a foreach and arrange them
foreach ($filename in $filenames) {
$GeneratedButton = New-Object System.Windows.Forms.Button
$GeneratedButton.Location = New-Object System.Drawing.Size($LeftSpace,$CurrentHeight)
$GeneratedButton.Size = New-Object System.Drawing.Size($ButtonWidth,$ButtonHeight)
$GeneratedButton.Text = $filename
# Action to take when button is clicked -- Open file and close form
$GeneratedButton.Add_Click({ Start-Process (Join-Path $BasePath $this.text) ; $form.Close() })
$form.Controls.Add($GeneratedButton)
$CurrentHeight += $ButtonHeight
}
# Activate the Form when loaded
$form.Add_Load({
$form.Activate()
})
# Show the form when loaded, but hide any results
$form.ShowDialog() > $null # Trash any output
