the [boolean] turned to be [string] ?

getvmdisktype.ps1

function getvmdisktype{
　　[boolean]$blndisktype=$true
    return $blndisktype
}

getvmdisktype.vb

    public function getvmdisktype() boolean
        strresult = runscript(getvmdisktype.ps1)
        return strresult
    end function

error:string "true  " can't turn be 'boolean' . 

why return "$blndisktype" become 'string'? , why there two" "after "true"?

hello.

you call getvmdisktype.ps1 not function, external powershell script. it's output converted [string] when printed stdout.
