转换格式表中的WMI创建日期 [英] Convert WMI Creationdate in Format-Table

问题描述

我正在尝试将我的计算机中的所有 svchost 进程放入格式良好的表中，该表包含格式化的日期时间，但到目前为止还没有这样做。

I'm trying to get all svchost processes from my machine into a nicely formatted table, containing a formatted datetime but so far have failed to do so.

这就是我将所有进程放入数组的方式

This is how I get all the processes into an array

$processes = @(gwmi -cl Win32_Process -f "name='svchost.exe'")

及其后按照我的要求打印日期时间但作为列表

and following prints the datetime as I'd like it them but as a list

$processes | % {$_.Caption, $_.ConvertToDateTime($_.CreationDate)} 
svchost.exe
vrijdag 4 september 2015 20:47:03
svchost.exe
vrijdag 4 september 2015 20:47:03
svchost.exe

，而将以下语句打印为我希望它们作为表，但不设置日期时间的格式

while following prints the statements as I'd like them as a table but without the formatting of the datetime

$processes | ft Caption, CreationDate -a
Caption     CreationDate             
-------     ------------             
svchost.exe 20150904204703.429503+120
svchost.exe 20150904204703.861565+120

我一辈子都无法弄清楚如何打印

I can't for the life of me figure out how to print it as

Caption     CreationDate             
-------     ------------             
svchost.exe vrijdag 4 september 2015 20:47:03
svchost.exe vrijdag 4 september 2015 20:47:03

推荐答案

使用选择对象代替 ForEach-Object 。这样一来，您可以选择对象的特定属性，还可以添加计算出的属性：

Use Select-Object instead of ForEach-Object. That allows you to select specific properties of your objects and also to add calculated properties:

Get-WmiObject -Class Win32_Process -Filter "name='svchost.exe'" | 
  Select-Object Caption,
                @{n='CreationDate'; e={$_.ConvertToDateTime($_.CreationDate)}}

如果您想这样做使用 ForEach-Object ，您必须创建新对象：

If you want to do this with ForEach-Object you'll have to create new objects:

Get-WmiObject -Class Win32_Process -Filter "name='svchost.exe'" | 
  ForEach-Object {
    New-Object -Type PSCustomObject -Property @{
      'Caption'      = $_.Caption
      'CreationDate' = $_.ConvertToDateTime($_.CreationDate)
    }
  }
