添加一个或多个元素到数组的开头

Easp.List.UnShift content
Easp.List.UnShift_ content

下列返回值仅 Easp.List.UnShift_ 方法

当 content 为字符串时，就是添加一个元素；当 content 为数组时，就是添加多个元素。

使用 Easp.List.UnShift_ 方法在原数组的数据加上新添加的数据，组成新的数组对象，不改变原数组的数据。

'创建一个List对象
Set list = Easp.List.New
list.Hash = "zero:零 one:壹 two:贰 three:叁"
 
'使用数组同时添加两个元素
list.UnShift Array("a:aaa", "b:bbb")
'取出为普通数组
arr = list.Hash
'循环输出
For i = 0 To Ubound(arr)
    Easp.WN("arr("& i &") => " & arr(i))
Next

arr(0) => a:aaa
arr(1) => b:bbb
arr(2) => zero:零
arr(3) => one:壹
arr(4) => two:贰
arr(5) => three:叁

'创建一个List对象
Set list = Easp.List.New
list.Hash = "zero:零 one:壹 two:贰 three:叁"
 
'取出为普通数组
Dim arr, arr2
arr = list.Hash '原数组
arr2 = list.UnShift_(Array("a:aaa", "b:bbb")).Hash '新数组
 
'循环输出
For i = 0 To Ubound(arr)
    Easp.WN("arr("& i &") => " & arr(i))
Next
Easp.WN "============"
For i = 0 To Ubound(arr2)
    Easp.WN("arr2("& i &") => " & arr2(i))
Next

arr(0) => zero:零
arr(1) => one:壹
arr(2) => two:贰
arr(3) => three:叁
============
arr2(0) => a:aaa
arr2(1) => b:bbb
arr2(2) => zero:零
arr2(3) => one:壹
arr2(4) => two:贰
arr2(5) => three:叁
