Describes how to create, use, and sort hashtables in PowerShell. Long description A hashtable, also known as a dictionary or associative array, is a compact data structure that stores one or more key-value pairs. For example, a hashtable might contain a series of IP addresses and computer...
$array[2] = 13 I just scratched the surface on arrays but that should put them into the right context as I move onto hashtables. What is a hashtable? I'm going to start with a basic technical description of what hashtables are, in the general sense, before I shift into the o...

直接赋值:输入类型和期望类型一致,可以直接交付。 基于语言的类型转换:当目标类型为void,Boolean,String,Array,Hashtable,PSReference(i.e.: [ref]),XmlDocument,Delegate和Enum时,基于语言的类型转换(.NET提供的)开始工作。 Parse 转换:如果目标类型包含了Parse()方法,则采用它。 Static Create 转换:如果目标类型包...

our new entry somehow became item 2 in a 4-item table. But that’s OK; before we go we’ll show you how to test for the existence of a key or a value regardless of their position in the hash table. And, just for the heck of it, we’ll show you how to sort the table as ...
