I'm having a problem with unexpected order of things being run and returned in the below Powershell script.
The Write-ArrayToTable function is to output the data in the arrays in a pretty table-like fashion via custom object.
The problem is when I call my Write-ArrayToTable function, it then does not return the data until AFTER the Read-Host command returns.
Below is the output from a run of the script, and the code itself is below that. The table output should be displayed BEFORE the Read-Host call but is instead held until the end and then displayed.
What am I missing? Any help greatly appreciated!
Output:
Test: y
Label1 Label2
------ ------
Test1 Test3
Test2 Test4
y
Code:
Function Write-ArrayToTable{
param(
[String[]]$Names,
[Object[][]]$Data
)
for($i = 0;; ++$i){
$Props = [ordered]#{}
for($j = 0; $j -lt $Data.Length; ++$j){
if($i -lt $Data[$j].Length){
$Props.Add($Names[$j], $Data[$j][$i])
}
}
if(!$Props.get_Count()){
break
}
[PSCustomObject]$Props
}
}
$arr1 = #("Test1","Test2")
$arr2 = #("Test3","Test4")
Write-ArrayToTable "Label1","Label2" $arr1,$arr2
Read-Host "Test"

Instead of dropping you objects like this:
[PSCustomObject]$Props
You can be more explicit:
$Props | Out-String
If you want to print all objects in one table, collect them first, before printing:
Function Write-ArrayToTable{
param(
[String[]]$Names,
[Object[][]]$Data
)
$myProps = for($i = 0;; ++$i){
$Props = [ordered]#{}
for($j = 0; $j -lt $Data.Length; ++$j){
if($i -lt $Data[$j].Length){
$Props.Add($Names[$j], $Data[$j][$i])
}
}
if(!$Props.get_Count()){
break
}
[PSCustomObject]$Props
}
$myProps | Format-Table
}
