由于Hashtable是引用类型,因此对Hashtable的赋值涉及浅表副本;也就是说,赋值的变量引用的是同一个Hashtable,不创建Hashtable的副本。 例如, PowerShell $h1= @{ FirstName ="James"; LastName ="Anderson"; IDNum =123}$h2=$h1$h1.FirstName ="John"# change key's value in $h1$h2.FirstName# chang...

$hashtable.<key> <value> 例如: PowerShell 复制 $hash.Number 1 $hash.Color Blue 哈希表具有 Count 属性,指示 hashtable中的键值对数。 PowerShell 复制 $hash.count 3 hashtable 表不是数组,因此不能将整数用作 hashtable中的索引,但可以使用键名称为 hashtable编制索引。如果键是字符串值,请将...

cases, you wouldn’t want all strings to suddenly be converted into a stream of characters. Or for a hash table, you wouldn’t likely want that to be auto-converted into a sequence of key/value pairs. In most cases you would want these types to be treated as lightweight scalar objects...
