How to return a string instead of system.object[] using powershell?

Question

I have a function

function Build-Exec($path,$param1,$param2,$param3,$param4)
{
    $var = @($path,$param1,$param2,$param3,$param4) -join " "  
    return $var 
}

when i call it it returns

System.Object[]

How can i make it return a string?

example usage

$var1 = Build-Exec("1","2","3","4","5") 

Write-Output $var1

Cannot reproduce. Maybe the variable names are mistyped, but since the sample doesn't have actual usage, it's just a guess. — vonPryz

The problem is that isn't how you define or call parameters for a function in PowerShell

function Build-Exec
{
    Param ($path,$param1,$param2,$param3,$param4)
    $var = @($path,$param1,$param2,$param3,$param4) -join " "  
    return $var 
}

Calling the function

$var1 = Build-Exec "1" "2" "3" "4" "5"
Write-Output $var1
1 2 3 4 5

When you include the commas, you are passing the first param a string array.
