PowerShell类；不动产；“系统.集合.专门化.定购词典”；；如何添加字典条目

（由于我已经在网上搜索了相当多的答案，但没有得到任何正确方向的提示，我允许自己问你以下问题：）

我有这样一个PowerShell类：

class settings
{
    [string]$CFG_Name
    [string]$CFG_Template_Path
    [string]$CFG_Target_Path
    [System.Collections.Specialized.OrderedDictionary]$ConfigSettings
}

$CurrentSettings = New-Object settings    <-- works fine
$CurrentSettings.CFG_Name = 'MPD'    <-- works fine
$CurrentSettings.CFG_Template_Path = $CFG_Template_MPD_Path    <-- works fine
$CurrentSettings.CFG_Target_Path = $CFG_MPD_Path    <-- works fine

$CurrentSettings.ConfigSettings.Add("TID",$EFT_TID)    <-- doesn't work

$CurrentSettings.ConfigSettings = New-Object System.Collections.Specialized.OrderedDictionary

然后我实例化这个类，并希望像这样使用它：

class settings
{
    [string]$CFG_Name
    [string]$CFG_Template_Path
    [string]$CFG_Target_Path
    [System.Collections.Specialized.OrderedDictionary]$ConfigSettings
}

$CurrentSettings = New-Object settings    <-- works fine
$CurrentSettings.CFG_Name = 'MPD'    <-- works fine
$CurrentSettings.CFG_Template_Path = $CFG_Template_MPD_Path    <-- works fine
$CurrentSettings.CFG_Target_Path = $CFG_MPD_Path    <-- works fine

$CurrentSettings.ConfigSettings.Add("TID",$EFT_TID)    <-- doesn't work

$CurrentSettings.ConfigSettings = New-Object System.Collections.Specialized.OrderedDictionary

---

$CurrentSettings=新对象设置解决方案如下：

在添加第一个字典条目之前，必须按如下方式初始化属性：

class settings
{
    [string]$CFG_Name
    [string]$CFG_Template_Path
    [string]$CFG_Target_Path
    [System.Collections.Specialized.OrderedDictionary]$ConfigSettings
}

$CurrentSettings = New-Object settings    <-- works fine
$CurrentSettings.CFG_Name = 'MPD'    <-- works fine
$CurrentSettings.CFG_Template_Path = $CFG_Template_MPD_Path    <-- works fine
$CurrentSettings.CFG_Target_Path = $CFG_MPD_Path    <-- works fine

$CurrentSettings.ConfigSettings.Add("TID",$EFT_TID)    <-- doesn't work

$CurrentSettings.ConfigSettings = New-Object System.Collections.Specialized.OrderedDictionary

然后可以添加条目：

$CurrentSettings.ConfigSettings.Add("TID",$EFT_TID)

你也可以做
.ConfigSettings=[ordered]@{TID=$EFT\u TID}
重复我看不出世界上哪里应该重复我的问题。与此无关。
