即使在 excel 关闭后存储/保存字典



我有一个字典,其中包含用户密钥 ->用户名引用。(我正在使用它来存储基于当前用户密钥在Windows目录中查找用户名后,因为我认为这是一个非常缓慢的过程,并且希望提高性能(

如果我在搜索中做对了,当我重新打开 excel 文件时,我的字典会被完全清除,对吗?

所以我想把它保存到其中一个工作表中,我想在下一个会话中重新创建它。(一列应保存用户密钥,另一列应保存名称(。

我的代码运行,但不在字段中写入任何值:

'will store the values on the rule sheets in row 4 following, columns BA and BB
Sub SaveDictToRulesSheet(dict As Object)
'startrow of list on excel sheet
startrow = 4
Dim i As Integer
i = 0
ActiveSheet.Name = "Rules"
        For Each key In dict.Keys
        Worksheets("Rules").Cells(startrow + i, "BA").Value = key
        Worksheets("Rules").Cells(startrow + i, "BB").Value = dict(key)
        i = i + 1
        Next key
i = 0
End Sub

任何帮助将不胜感激。

所以我想把它保存到其中一个工作表中,我想在下一个会话中重新创建它。(一列应保存用户密钥,另一列应保存名称(。

嗯,这部分似乎很简单。有点令人困惑的是你在字典中读到的地方。你参考它,但我不清楚值被加载到哪里。我将向你们展示我将如何做到这一点。希望这有所帮助,我已经正确理解了这个问题。

将字典列写入空白/当前工作簿并保存。然后创建一个新的 sub 来操作如下内容:

Sub Retrieve_Dict()
    Set wbkCSV = Workbooks.Open("Template.xlsx")
    Set wshCSV = wbkCSV.Worksheets("Rules")
    Set dict = CreateObject("Scripting.Dictionary")
    numrows = application.worksheetfunction.counta(wshCSV.Columns(27)) - 5
    numcols = 2
    set wshRange = wshCSV.Range("BA5").Resize(numrows,numcols)
    tempArray = wshRange.value
    for i = 1 to ubound(tempArray) ' Read rows, columns, send to dict.
        dict.key(tempArray(i, 1)) = tempArray(i, 2)' read values.
    Next i
    tempArray = Process(dict)  ' Func. updating dictionary values. 
    wshRange.value = tempArray
    wbkCSV.Close (True)
End Sub

当然,如果您打开外面的工作簿,然后传递工作表,则可以使上述子成为函数。该函数可以作为对象/脚本字典返回,具体取决于您的绑定。

另外,请注意,我可能弄错了偏移量/行数。但我认为,一般原则应该适用。

下面的代码:

  • TestDictionaryOps() - 测试从工作表中写入和读取
  • DictionaryToRange() - 将字典写入工作表
  • DictionaryFromRange() - 从工作表中读取字典

将其粘贴到新的标准模块中,然后在新工作表上运行它(Sheet4(

    DictionaryToRange d, Sheet4
