用于对多个组的成员进行计数且无重复项的PowerShell脚本

# 创建一个空的哈希表
$memberCount = @{}

# 定义多个组的成员
$group1Members = "User1", "User2", "User3"
$group2Members = "User2", "User3", "User4"

# 遍历组的成员，进行计数
foreach ($member in $group1Members) {
    # 检查成员是否已存在于哈希表中
    if ($memberCount.ContainsKey($member)) {
        # 如果已存在，则增加计数
        $memberCount[$member]++
    } else {
        # 如果不存在，则添加到哈希表，并设置计数为1
        $memberCount[$member] = 1
    }
}

foreach ($member in $group2Members) {
    if ($memberCount.ContainsKey($member)) {
        $memberCount[$member]++
    } else {
        $memberCount[$member] = 1
    }
}

# 输出计数结果
foreach ($member in $memberCount.Keys) {
    Write-Host "成员 $member 的计数为 $($memberCount[$member])"
}
