PowerShell读取CSV并遍历数组的流程步骤

# 1.1 读取CSV文件并提取Group列的值到数组
$groups = Import-Csv -Path "你的文件路径.csv" | Select-Object -ExpandProperty Group
 
# 1.2 遍历数组并输出所有元素
foreach ($group in $groups) {
    Write-Output "当前组: $group"
}
 
# 2.1 或者使用管道简洁写法（效果相同）：
Import-Csv "你的文件路径.csv" | ForEach-Object { 
    Write-Output "当前组: $($_.Group)" 
}

Name,Group
Alice,Admin
Bob,Developer
Charlie,Admin

当前组: Admin
当前组: Developer
当前组: Admin
当前组: Manager

$groups | Where-Object { $_ } | ForEach-Object { Write-Output "组: $_" }

$uniqueGroups = Import-Csv groups.csv | Select-Object -ExpandProperty Group | Sort-Object -Unique

$uniqueGroups = Import-Csv "D:\Workspace\Data\powershell\group.csv" | Select-Object -ExpandProperty Group | Sort-Object -Unique
 
# 1.2 遍历数组并输出所有元素
foreach ($group in $uniqueGroups) {
    Write-Output "当前组: $group"
}
