Unable to get the selected item directly

I just learned about powershell gui programming. The following code can be executed successfully, but the result of the execution is not the text of the item in the list.

like this:

@{Name=a1; Status=True}

@{Name=a2; Status=False}

I need to output the text of the item directly.

a1

a2

I tried a lot of methods but no results Thanks in advance

function Show-7_psf {

If you want any other property then replace with name 

$buttonOk_Click = {
   $checkedlistbox1.CheckedItems | Where-Object { $_."Name" | Write-Host }
}

Change this line

$checkedlistbox1.CheckedItems | Write-Host

To 

$checkedlistbox1.CheckedItems.Name | Write-Host

This is because you are calling the object in the $csv array but not selecting the Property so you are returning the entire object in the array.
