我有一个带有功能的模块，该功能使用库中的HPRESTCmdlets模块收集HP服务器上的固件版本。该函数为对象分配一个类型名称“Hardware.Firmware”。我正在使用ps1xml进行自定义查看。
该功能由Begin，Process和End脚本块组成。当针对一组对象运行该函数时（通过foreach），第一个对象总是在输出中延迟到控制台，它实际上在End块运行后显示。每个顺序对象都按预期运行。如果针对单个对象运行，我也会收到相同的延迟。
如果删除自定义typename，则第一个对象没有延迟并且处理正确。关于为何在使用自定义类型时处理第一个对象有延迟的任何想法，我该如何避免？
以下是该函数的代码：
function Get-HPFirmware {
[CmdletBinding()]
Param(
[Parameter(Mandatory = $true, Position = 0)]
[Alias('Name', 'Server', 'Ip')]
[string]$iLoName,
[Parameter(Mandatory = $true)]
[ValidateNotNullorEmpty()]
[Alias('User')]
[System.Management.Automation.PSCredential][System.Management.Automation.Credential()]
$Credential,
[switch]$IgnoreCertFailures

答案 0 :(得分：1)
在PetSerAl上面设置ps1xml中的列宽确实解决了问题。原因是，当你有一个自定义格式并且你没有指定宽度时，PowerShell必须等到它看到每个对象，这样才能找出尝试和制作每个列的宽度。
除了宽度，命令在管道Get-HPFirmware |上看起来像这样格式表-Autosize |的Out-Default。自动调整大小会阻塞管道上的输出，直到达到Out-Default。
