虽然我可以把所有的数据显示到终端上;导出时，Hostname列将填充System.Object[]。我需要添加到更多的列，但在以前的尝试你也填充示例：oUTPUT_eXAMPLE

获取主机信息

$hosts = Get-VMHost

初始化一个空数组来存储数据

$serviceTags = @()

遍历每台主机

foreach ($hostsname in $hosts) 
 {
    **#Retrieve Datacenter, hostName and Model**
    $mydatacenter = Get-Datacenter -VMHost $hosts
    write-host "Completed Datacenter..."
    $vhostName = $hosts.Name
    write-host "Completed Hosts..."
    $model = $hosts.ExtensionData.Summary.Hardware.Model
    write-host "Completed Model..."   
    $serviceTag = ($hostsname| Get-View).Hardware.SystemInfo.OtherIdentifyingInfo |
        Where-Object { $_.IdentifierType.Key -eq "ServiceTag" } |
        Select-Object -ExpandProperty IdentifierValue
    write-host "Completed ServiceTag"

   # Create a custom object with Datacenter, host name Model and service tag

    $serviceTagInfo = [PSCustomObject]@{
       DataCenter = $mydatacenter
       HostName = $vhostName
       Model = $model
       ServiceTag = $serviceTag
       }

    # Add the object to the array
    $serviceTags += $serviceTagInfo

}
# Export the data to CSV
$serviceTags | Export-Csv -Path "c:\Users\myuser\Documents\ServiceTags2.csv" -NoTypeInformation
