我试图弄清楚如何从具有适当列的 PowerShell 对象创建 .csv。我想创建一个包含三列（用户 ID、国家/地区、计数）的 .csv 文件。它还需要先按用户 ID 排序，然后按国家/地区（A 到 Z）。在下面的示例代码中，我希望输出如下所示：
用户 ID、国家、计数 鲍勃，中国，2 乔，加拿大，1 乔，美国，1
$path = "C:\test\test.csv"
Set-Content -Path $path -Value “UserId, Country”
Add-Content -Path $path -Value "Joe, United States", "Bob, China", "Bob, China", "Joe, Canada"
(Import-Csv -Path $path) | Group-Object -Property UserID, Country -NoElement | Select-Object * -ExcludeProperty Values, Group | Select-Object @{Name="User ID, Country";Expression={$_.Name}}, Count | Export-Csv -Path $path -NoTypeInformation -Force
Get-Content -Path $path不幸的是，当我运行它时，用户 ID 和国家/地区位于以下同一列中：
“用户 ID，国家/地区”，“计数” "乔，美国","1" “鲍勃，中国”，“2” "乔，加拿大","1"
我相信问题源于Select-Object @{Name="User ID, Country";Expression={$_.Name}}. 我怎样才能让它按照上面的要求排列在三列中？顺便说一句，我不完全理解问题代码的语法。如果您能解释@{Name="User ID, Country";Expression={$_.Name}}它的作用，我将不胜感激。
编辑 这是我的实际代码，以防万一这有助于解决问题。
