asp中Scripting.Dictionary字典对象使用示例

Dim objDict
Set objDict = WSH.CreateObject("Scripting.Dictionary")
  ' .Add(key, value)    
  objDict.Add "a", "value1"
  objDict.Add "b", "value2"
  objDict.Add "c", "value3"
  '直接通过key=b索引到value2
  WSH.Echo objDict.Item("b")
  objDict.Remove "b" ' 删除索引b及其对应的值
    
  ' 以下是遍历字典
  Dim objKeys, objItems, i
  objKeys = objDict.Keys
  objItems = objDict.Items
  For i = 0 To objDict.Count -1
    WSH.Echo "Key=" & objKeys(i) &_
             " AND Value=" & objItems(i)
  Next
  ' 判断指定的key是否存在
  If objDict.Exists("b") Then
    WSH.Echo "Found it"
  Else
    WSH.Echo "Not Exists!"
  End If
  objDict.RemoveAll  ' 清空字典内所有的key及其对应value
Set objDict = Nothing
