结果中缺少 Powershell 脚本属性

Question

我不确定脚本有什么问题。我有一个包含 Name,Count,Owner 的 3 列 csv 文件。目标是获得每个名字的最高计数，然后输出所有 3 列，但是 Owner 列不输出。我只得到 Name, Total。如果有人能帮助我指出问题所在，我将不胜感激，非常感谢。

$total = Import-Csv -Delimiter ',' -Path "file.csv"

$total = $total | Group-object -Property Name | Select Name,  @{ N = 'Total';E = {($_.Group | Measure-Object -Property count -Maximum).Maximum }},Owner

csv 文件的内容：

"Name","Count","Owner"
"ctx_Prd-DG","1","User1"
"PRD-Fa","5","User2"
"ING-PROD","3","User2"
"PROD-DG03","0","User2"
"PROD-DG01","0","User2"
"PRD-2018-DG","1","User3"
"PRD-7-DG","5","User3"
"PRD-7-DG-PR15","0","User3"
"PRD-CS-DG","0","User3"
"PRD-INSIGHT-DG","0","User3"
"PRD-LIVE-DG","0","User3"
"DC01-DG","0","User4"
"Test - DG","0","User4"
"PRD-CS-DG","0","User3"
"INSIGHT-DG","0","User3"
"ctx_Prd-DG","1","User1"
"PRD-Fa","1","User2"
"ING-PROD","0","User2"
"PROD-DG03","0","User2"
"PROD-DG01","0","User2"
"PRD-2018-DG","7","User3"
"PRD-7-DG","5","User3"
"PRD-7-DG-PR15","0","User3"
"PRD-CS-DG","0","User3"
"PRD-INSIGHT-DG","0","User3"
"PRD-LIVE-DG","2","User3"
"DC01-DG","1","User4"
"Test - DG","8","User4"
"PRD-CS-DG","20","User3"
"INSIGHT-DG","0","User3"

Answer 1

你考虑过这个选项吗？

$total = Import-Csv -Path file.csv
$grouped = $total | Group-Object -Property Name
$output = $grouped | Select-Object Name, @{ N = 'Total'; E = {$_.Count} }, @{ N='Owner'; E= {($_.Group).Owner}}

关于 "Name,Expression" 语法，这是 SO 中发布的一个有用的问题。

Select-Object expression

Answer 2

只是$total | Group-Object -Property Name没有属性"Owner"

# `Get-Member -MemberType Properties` shows properties of an object.
$group = $total | Group-Object -Property Name
$group | Get-Member -MemberType Properties

# See how `Group-Object` groups each item,
$group[1].Group
$group[2].Group

所以你的代码会像下面这样

$csv =  Import-Csv "file.csv"
$total = $csv | Group-Object -Property Name | Select Name,  @{
  N = 'Total'
  E = { ($_.Group | Measure-Object -Property count -Maximum).Maximum }
}, @{
  N = 'Owner'
  E = { $_.Group.Owner[0] }
}
