是否有函数或属性可以获取变量名称？
就像是
msgBox myVariable.name
or
msgBox nameOfVariable(myVariable)
返回"myVariable"当我用例如定义它时myVariable = "whatever"？
谷歌只是给变量引用带来了问题......
可能的类方法如下（已评论）：
-
添加类模块
在 VBA 集成开发环境中
单击插入->类模块
单击视图 -> 属性窗口
enter (Name)属性文本框并输入“变量”（或您可能喜欢的任何内容，但要与以下步骤保持一致）
-
在中输入以下代码Class代码窗格
Option Explicit
'declare the fields that will be attached to every instance of this class
Public name As String '<--| this will store the name of the variable to which you'll set the object of this class
Public value As Variant '<--| this will store the value associated with the variable to which you'll set the object of this class
'declare a `method` to write the `value` of the object in the named range named after the `name` field
Sub WriteRange(Optional wb As Variant) '<--| you can pass the reference of the workbook whose named ranges you want to exploit
If IsMissing(wb) Then Set wb = ActiveWorkbook '<--| if no workbook reference is passed then the currently active workbook is assumed
If TypeName(wb) = "Workbook" Then '<-- check for a proper workbook reference being passed)
On Error Resume Next '<-- to prevent unassigned named range throw an error
wb.Names(name).RefersToRange.value = value '<--| write the value of the `value` filed of the current instance in the named range of the passed workbook named after the `name` filed of the current instance
End If
End Sub

Exploit Variable代码中的类
作为利用的一个例子Variable三个变量的类，例如String第一个值，一个Integer第二个和 a 的值Double对于第三个值，在任何模块代码窗格中输入以下代码：
Option Explicit
Sub main()
Dim myVariable1 As Variable, myVariable2 As Variable, myVariable3 As Variable '<--| declare your variables of type "Variable": choose whatever name you may want
Set myVariable1 = CreateVariable("myVariable1", "this is a string value") '<-- set your 1st variable with its name (you must use the same name as the variable!) and value (myVariable1 will have a `String`type value)
Set myVariable2 = CreateVariable("myVariable2", 10) '<-- set your 2nd variable with its name (you must use the same name as the variable!) and value (myVariable2 will have a `Integer`type value)
Set myVariable3 = CreateVariable("myVariable3", 0.3)'<-- set your 3rd variable with its name (you must use the same name as the variable!) and value (myVariable3 will have a `Double` type value)
'exploit `WriteRange` method of your Class to write the object value into the corresponding named range: you must have set proper named ranges in your currently active workbook
myVariable1.WriteRange '<--| this will write the string "this is a string value" in named range "myVariable1" of your currently active workbook
myVariable2.WriteRange '<--| this will write the number '10' in named range "myVariable2" of your currently active workbook
myVariable3.WriteRange '<--| this will write the number '0.3' in named range "myVariable3" of your currently active workbook
End Sub
' helper Function to create an object of `Variable` class and initialize its `name` and `value` properties
Function CreateVariable(name As String, value As Variant) As Variable '<--| the function returns an object of `Variable` class
Set CreateVariable = New Variable '<--| this creates a new object of `Variable` class
With CreateVariable '<--| refer to the newly created object and ...
.name = name '<--| ... set its `name` property ...
.value = value '<--| ... and its `value` property
End With
End Function
