PowerShell哈希表顺序

Question

The below script is running in a for-each loop and the output heading is not coming in the right order. I want the output order as I mentioned in the hash table. I want the CSV table column heading in right order , not the data inside the table.

Like 1.Machine_Name, 2.Ping_Status, 3.OS_Name

How can I solve this?

$Result = @{
            MACHINE_NAME     = "$_"
            PING_STATUS      = "MACHINE ONLINE"
            OS_NAME = "$OSNAME"
        }

$Details += New-Object PSObject -Property $Result
$Details | export-csv -Path $pathofcsv -NoTypeInformation

Answer 1

Use an ordered hash table:

$Result = [ordered]@{             
            MACHINE_NAME     = "$_" 
            PING_STATUS      = "MACHINE ONLINE"
            OS_NAME = "$OSNAME"
        }

$Details += New-Object PSObject -Property $Result
$Details | export-csv -Path $pathofcsv -NoTypeInformation

Answer 2

要强制执行顺序，请使用Select-Object ：

$Details | Select-Object MACHINE_NAME, PING_STATUS, OS_NAME | export-csv -Path $pathofcsv -NoTypeInformation
