VBA: 字典的介绍与实例

基本语句

Sub dictest()' 其他可供参考的详细解说： http://club.excelhome.net/thread-868892-1-1.html' 字典简介' 字典对象相当于一种联合数组，它是由具有唯一性的关键字（Key）和它的项（Item）联合组成' VBA字典有6个方法Add , Keys, Items, Exists, Remove, RemoveAll' VBA字典有4个属性Count , Key, Item, CompareMode' 创建字典"d"Dim d As ObjectSet d = CreateObject("Scripting.Dictionary")' 添加d.Add "a", "example1"d.Add "b", 9'd.Add "b", 7 'add重复key会报错d("b") = 7    '这样会直接覆盖,不会报错'd.Item("b") = 7 '与上者相同d("c") = "example2"'通常使用Sting文本字符串作为字典key关键词，也可以使用数字、数值作为key'速度：纯数字>纯文本字符>>>文本/数值混合型' 输出Cells(1, 1) = d("a")'Cells(1, 1) = d.Item("a") '与上者相同Cells(1, 2) = d("b")Cells(1, 3) = d("c")' 字典成员个数Cells(1, 4) = d.Count'移除d.Remove ("b")'d.RemoveAll  '移除所有' key是否存在Cells(2, 1) = d.Exists("b")d.Add "b", 7Cells(2, 2) = d.Exists("b")' 替换keyd.Key("a") = "e"'所有key所在的数组和所有item所在的数组d_keys = d.KeysCells(3, 1) = d_keys(0)Cells(3, 2) = d_keys(1)d_items = d.ItemsCells(4, 1) = d_items(0)Cells(4, 2) = d_items(1)'更改字符串关键字比较时所使用的比较模式'd.CompareMode = 0(二进制）/1(文本)/2(数据库）End Sub

结果如下
