将逗号分隔的字符串转换为列表

Question

我有以下powershell代码：

$Credentials = 'Credentials: myacct1,myacct2'

$runtimes = $Credentials -match "Credentials: (?<content>.*)"
$runtimeList = $matches['content']
Foreach ($runtime in $runtimeList)
{
    Write-Host $runtime
}

那只是返回myacct1,myacct2我想要它遍历列表的地方

myacct1
myacct2

Answer 1

我敢肯定，你只需要通过拆分匹配的字符串,使用String.Split()

$Credentials = 'Credentials: myacct1,myacct2'

$runtimes = $Credentials -match "Credentials: (?<content>.*)"
$runtimeList = $matches['content'].Split(",")
Foreach ($runtime in $runtimeList)
{
    Write-Host $runtime
}

# Output:
# myacct1
# myacct2

Answer 2

要提供更多PowerShell惯用的解决方案：

PS> 'Credentials: myacct1,myacct2' -replace '^Credentials: ' -split ','
myacct1
myacct2

• -replace '^Credentials: '从字符串中-replace '^Credentials: '前缀Credentials:用（隐含的）空字符串替换）。
• -split ','由分割剩余的字符串转换成令牌的阵列,
