是否可以在 Dictionary 对象中包含一个数组 [英] Is it possible to have a array inside a Dictionary object

问题描述

我知道组合到类似的数据结构是不合逻辑的，但很想知道我们是否可以在 Dictionary 对象中包含一个数组元素.类似的东西:

I knew that combining to similar data structures wouldn't be logical but curious to know if we can have a array element inside Dictionary object. some thing like:

Set d = CreateObject("Scripting.Dictionary")

d.Add "Name", "John"
d.Add "Age", 31
d.Add "Company", Array("microsoft", "apple")

推荐答案

您离自己解决问题只有一个 WScript.Echo:

You are one WScript.Echo away from solving the question for yourself:

>> Set d = CreateObject("Scripting.Dictionary")
>> d.Add "Company", Array("microsoft", "apple")
>> WScript.Echo Join(d("Company"))
>>
microsoft apple

更新(感谢@Ansgar):

.Item()(和For Each)传递的元素是副本；和数组赋值也复制(不像其他语言那样引用).因此，更改存储在字典中的数组元素意味着分配一个新数组:

The elements delivered by .Item() (and For Each) are copies; and Array assignment copies too (does not take a reference as in other languages). So changing an array element stored in a dictionary means assigning a new array:

>> Set d = CreateObject("Scripting.Dictionary")
>> d.Add "Company", Array("microsoft", "apple")
>> WScript.Echo Join(d("Company"))
>> d("Company") = Array(d("Company")(1), "samsung")
>> WScript.Echo Join(d("Company"))
>>
microsoft apple
apple samsung

有时使用(另一个)字典、System.Collections.Arraylist 或自定义对象(所有对象都是引用，因此赋值可以访问原始元素)更方便.

Sometimes it's more convenient to use a(nother) dictionary, a System.Collections.Arraylist, or a custom object (all objects are references, so an assignment gives access to the original element).
