Question

我有一个简单的PowerShell脚本，它查看机器的IP地址，然后根据子网将楼层分配给另一个变量。我目前有一个带有ip地址的数组和一个for语句，用于每个循环以匹配发言权并分配一个变量。我想将此作为哈希表或多维数组执行，但遇到了数组问题。尝试了几个不同的迭代，但我不能让它工作。它是最接近的。

$FloorIpTest = @{"10.7.20" = "20"; "10.7.21" = "21"; "10.7.22" = "10.7.22"}
[string]$testip = "10.7.20"
Foreach ($value in $FlooripTest.ContainsKey($testip)){write-host $Value.Values}

当我跑$FlooripTest.ContainsKey($testip)时，我收到了真实的

但我从上面得不到输出。任何建议将不胜感激。

Answer 1

你在找这样的东西吗？

$Floors = @{"10.7.20" = "20"; "10.7.21" = "21"; "10.7.22" = "22"}

$testip = "10.7.20.123"

$Floor = $Floors[$testip.Substring(0, $testip.LastIndexOf('.'))]
$Floor

首先使用get-member

查找可调用的方法和属性

$FloorIpTest = @{"10.7.20" = "20"; "10.7.21" = "21"; "10.7.22" = "10.7.22"}
$FloorIpTest | get-member


   TypeName: System.Collections.Hashtable

您已有哈希表。如果你想使用GetHashCode方法。但据我了解，您只想迭代所有成员。

$FloorIpTest = @{"10.7.20" = "20"; "10.7.21" = "21"; "10.7.22" = "10.7.22"}
[string]$testip = "10.7.20"
Foreach ($key in $FlooripTest.Keys)
{
    write-host "key: $key"
    write-host "value: $FlooripTest[$key]"
    write-host "hashcode: $FlooripTest[$key].GetHashCode()""
}
