foreach($itemin$array) {Write-Output$item}Write-Output$array[3] 同样,你可以使用索引来更新值 $array[2] = 13 这里我仅仅介绍了数组的一些皮毛,但是把我们下面将要讨论的hashtable引到了正确的话题上. 我们首先从一般的,被许多编程语言都采用的技术性描述开始,然后再转到powershell里对它的
$array = @(1, 2, 3, 4, 5) # 遍历数组 foreach ($element in $array) { # 判断条件,筛选偶数 if ($element % 2 -eq 0) { # 添加满足条件的元素到哈希表 $hashTable.Add($element, $element) } } # 输出筛选结果 $hashTable 在这个示例中,我们创建了一个空的哈希表$hashTable,然后遍历数组...
You’ll notice something funny about the last example: we had to cast or convert the sorted list into an array of strings. This is because the hashtable keys mechanism expects strings, not objects, as keys. There’s much more on casts later in this chapter. 你会注意到最后一个例子中有些...
$array= @(1,2,3,5,7,11) 将项放入数组后,可以使用foreach来循环访问该列表,或者使用索引访问数组中的各个元素。 powershell foreach($itemin$array) {Write-Output$item}Write-Output$array[3] 还可以使用索引以相同方式更新值。 powershell $array[2] =13 ...
$hash.CopyTo($array,0); foreach($item in $array) { "key:"+$item.Key; "value:"+$item.Value; } 我相信你已经很清楚的知道powershell中hashtable的遍历了。 如果需要了解hashtable的相关知识,请访问:http://technet.microsoft.com/zh-cn/library/ee692803(en-us).aspx ...
PS> ([array]$hash.Values)[2] one 在字典中使用索引表示法时,括号内的值会根据其类型进行解释。 如果值为整数,则将其视为值集合中的索引。 如果值不是整数,则它被视为键名称。 例如: PowerShell PS>$dictionary[1] two PS> ([array]$dictionary.Values)[1] two PS>$dictionary[[Object]1] one PS...

If the array is named $ip, then you access the first item in the array by using:PowerShell Copy $ip[0] You can use a hash table to store both IP addresses and the computer names as the following table depicts.Table 2: Using a hash table to store IP addre...

This is how we get the first item in our array:powershell Copy PS> $data = 'Zero','One','Two','Three' PS> $data[0] Zero The reason why we use zero here is because the first item is at the beginning of the list so we use an offset of 0 items to get to it. To get ...
