我知道很多人都问过关于这个错误的问题,但是根据这些问题的答案,我应该做好一切。
我创建了一个名为Variable的类来存储有关变量的多个信息片段。我有另一个名为Equipment的类,它存储这些变量的数组。以下是Equipment中的相关代码
Public name As String
Private variables() As Variable
Public Sub setVariables(vars() As Variable)
variables = vars
End Sub我还有一个创建Equipment实例的模块。以下是这方面的所有代码:
Public Sub fillEquipment()
'figure out how many units of equipment there are
numUnits = 0
atRow = 1
Do Until Range("A" & atRow).value = ""
numUnits = numUnits + 1
atRow = atRow + 1
Loop
'create array for equipment units
Dim units() As Equipment
ReDim units(0 To numUnits)
'figure out how many variables there are
numVars = 0
For Each col In Range("A1:ZZ1")
If col.value <> "" Then
numVars = numVars + 1
End If
Next col
'create an array of equipment one row at a time
atRow = 1
Do Until Range("A" & atRow).value = ""
'create and name equipment
units(atRow) = New Equipment
units(atRow).name = Range("A" & atRow).value
'create an array of vars
Dim variables() As Variable
ReDim variables(0 To numVars)
For atCol = 1 To numVars
variables(atCol) = New Variable
variables(atCol).name = Cells(1, atCol).value
variables(atCol).value = Cells(atRow, atCol).value
Next atCol
'add variables to equipment
units(atRow).setVariables (variables)
atRow = atRow + 1
Loop
'print for testing
For atRow = 1 To numUnits
Cells(atRow, 1).value = Equipment(atRow).name
For atCol = 1 To numCols
Cells(atRow, atCol + 1).value = Equipment(atRow).getVariables(atCol)
Next atCol
Next atRow
End Sub我的问题是:当我运行这个程序时,它会在variables ( units(atRow).setVariables (variables) )一词上给出一个编译器错误“Type失配:数组或用户定义的类型”。
我不明白我做错了什么。variables被定义为Variable对象类型的数组,这正是setVariables所要求的。
谢谢!我真的很感激你的帮助!!

你有额外括号。这在编译过程中没有错误:
Sub make(numUnits As Long, numVars As Long)
Dim units() As Equipment
ReDim units(0 To numUnits)
Dim atRow As Long, atCol As Long ' <-- new Dim, because of Option Explicit
'create an array of equipment one row at a time
atRow = 1
Do Until Range("A" & atRow).value = ""
'create and name equipment
units(atRow) = New Equipment
units(atRow).name = CStr(Range("A" & CStr(atRow)).value) ' <-- use CStr() anytime you need a string
'create an array of vars
Dim variables() As Variable
ReDim variables(0 To numVars)
For atCol = 1 To numVars
variables(atCol) = New Variable
variables(atCol).name = Cells(1, atCol).value
variables(atCol).value = Cells(atRow, atCol).value
Next atCol
'add variables to equipment
units(atRow).setVariables variables
atRow = atRow + 1 ' ^^^^^^^^^ not (variables) - no parens
Loop
End Sub关键问题是括号。但是,这也会为变量添加Dim语句。正如@BruceWayne所说,您应该始终使用Option Explicit。是的,在每个模块和每个类模块中都是如此。否则,就会丢弃编译器的调试辅助。
实际上,我还在每个模块的顶部使用了Option Base 0,主要是为了提醒自己在哪个系统中工作:)。
编辑我添加了一些CStr,它可以保护您免受奇怪的角落情况的影响。如果要进一步开发这段代码,我建议使用显式工作表变量,而不是依赖于隐式ActiveSheet。参见,例如,这个答案。
