powershell - 如何创建适用于格式表的 PowerShell 数据结构

问题描述

当我执行“$states2 | ft”时，我得到了这个：

Name                           Value
----                           -----
NY                             State
AZ                             State

当我宁愿得到这个时：

Name    Acres   Population   Founded  FullName
----    -----   ----------   -------  --------
NY        50           100      1645  New York
AK       100           512      1745  Alaska

我究竟做错了什么？

这是我的类形式的数据结构：

class State {
    [Int64]$Acres
    [Int64]$Population
    [Int16]$Founded
    [string]$FullName
    }

$States2 = @{}
$States2.AK = [State] @{Population = 512; Founded = 1745; Acres = 100; FullName = "Alaska"}

$States2.NY = [State]::new()
$States2.NY.Acres       = 50
$States2.NY.Population = 100
$States2.NY.Founded    = 1652
$States2.NY.FullName   = "New York"

提前致谢

解决方案

您需要将缩写名称作为类定义的一部分：

class State {
    [string]Name
    [Int64]$Acres
    [Int64]$Population
    [Int16]$Founded
    [string]$FullName
}

$States2 = @{}
$States2.AK = [State] @{Name = "AK"; Population = 512; Founded = 1745; Acres = 100; FullName = "Alaska"}

$States2.NY = [State]::new()
$States2.NY.Name       = "NY" 
$States2.NY.Acres      = 50
$States2.NY.Population = 100
$States2.NY.Founded    = 1652
$States2.NY.FullName   = "New York"

如果您只想显示哈希表中的值，请执行以下操作：$States2

$States2.Values |Format-Table
