Scope/persistence 数据问题
Scope/persistence of data issue
我不确定要搜索什么来解决这个问题。我有一个 scope/persistence 的数据问题，其中用于填充我的数据结构的变量覆盖了数据结构 (ImageFileName) 中的其他项目。这是我的代码：

我可以看到在运行 9 行之后，$result 中的每个 ImageFileName 都是相同的。我该怎么做才能维护从方法返回的内容？现在我正在尝试使用 New-Object，但它并没有解决问题。
这是 $resultHelp 的样子：
[0] $true (I'm not sure why it puts true at the top) [1]
@(HelpCode=9;ScreenNumber=1;TextID=HELP_...JA;PictureID=HELP_...RIB)
[2]
@(HelpCode=9;ScreenNumber=2;TextID=HELP_...ROLL;PictureID=HELP_...ROLL)
[3]
@(HelpCode=9;ScreenNumber=3;TextID=HELP_...EDGE;PictureID=HELP_...UT)
...
我正在使用 Powershell 5.1 和 VSCode。
更新：
我再次检查，在 Get-ImageName 中，它返回一个类似“Contact_Service”...bmp 的文件名，看起来它被放入 psObject ImageFileName...($imageNamePath) ，对于找到的其他图像也是如此。当我最后查看时，$result 对那个 ImageFileName 具有所有相同的值。和以前说“Contact_Service”..bmp 的那个现在是另一回事，与 $result.
中的其他匹配
更新 2：
有几个错误：
New-Object : A constructor was not found. Cannot find an appropriate
constructor for type System.Drawing.Image
和
New-Object : A constructor was not found. Cannot find an appropriate
constructor for type System.String.
对于我在主代码中尝试处理对象覆盖问题的地方
更新 3：
在我将 psobject 整理好后，我将其放入带有 Export-Excel 的电子表格中。我只是想提供此信息，以便您知道我为什么将其放在 psobject 中：
$xlsx = $result | Export-Excel -Path $outFilePath -WorksheetName $errCode -Autosize -AutoFilter -FreezeTopRow -BoldTopRow -PassThru # -ClearSheet can't ClearSheet every time or it clears previous data
我想通了。
问题是，即使我找到不同的 $imageNamePaths 以分配给 属性 作为每个 PictureID 的 ImageFileName，并在 foreach 循环中的 psobject 中分配这些属性，我最终还是得到了每个 ImageFileName 属性（覆盖）都一样。这修复了它。
New-Object psobject -Property $([ordered]@{
ScreenNumber = $($row.ScreenNumber)
KPMKey = $($row.TextID)
EnglishUS = $($longText)
PictureID = $($row.PictureID)
ImageFound = ""
ImageFileName = "$($imageNamePath)" ####added double quotes
})
双引号让不同的 $imageNamePath 值保留而不是 over-written。我不太清楚为什么。
谢谢@Mathias，我将抑制我的 -Match 的输出，以查看是否从函数返回的数据顶部删除了 $true。 :)
