Powershell包含-是否匹配部分字符串和列表？

Question

我的脚本中有这样的情况：

$Excludes = "Commvault","Veeam"

$testuser = 'DOMAIN\vCommvaultConnect'
$Excludes | ForEach-Object {
    If ($testuser.Contains($_)) {
    Write-Host "Found"
    }
}

这是最有效的测试方法，还是有更快的方法将用户与这些排除的单词进行匹配？

使用正则表达式搜索组如何

$Excludes = "Commvault","Veeam"

$SearchRegex_Excludes = ($Excludes | % { "(" + ($_) + ")" }) -join "|"
# sample regex pattern result - (Commvault)|(Veeam)

$testuser = "DOMAIN\vCommvaultConnect"

if ( $testuser -match $SearchRegex_Excludes ) { "Found" } else { "Not Found " }
