PowerShell中的一个switch的例子

在这个例子中, 应该注意

• Switch语句里对数字范围条件的使用
• break的使用
• 字符串的拼接
• 数组的声明

 

$array = @(1,6,7,8,11,15,16)
foreach ($element in $array)
{
    switch($element)
    {
        {$_ -le 5} {Write-Host $($element.ToString() + " is less than 5.";break) -foreground Green}
        {$_ -le 10} {Write-Host $($element.ToString() + " is less than 10.";break) -foreground Yellow}
        {$_ -le 15} {Write-Host $($element.ToString() + " is less than 15.";break) -foreground Red}
    }
}
