在PowerShell中不使用if循环的代码问题

$variable = "value"

switch ($variable) {
    "value1" {
        # 执行代码块1
    }
    "value2" {
        # 执行代码块2
    }
    default {
        # 执行默认代码块
    }
}

$variable = "value"

$result = ($variable -eq "value1") ? "result1" : (($variable -eq "value2") ? "result2" : "default result")

$variable = "value"

$validValues = @("value1", "value2")

if ($validValues.Contains($variable)) {
    # 执行代码块
}
