VBA怎么传入数组数据

在VBA（Visual Basic for Applications）中，你可以通过以下几种方式传递数组数据：

1. **ByRef参数**：如果你需要修改数组元素，可以将数组作为ByRef参数传递。例如：

Public Sub ProcessArray(ByRef arr() As Variant)
    '...这里可以直接操作arr数组...
End Sub

Dim myArray(1 To 5) As Integer
Call ProcessArray myArray 'myArray会在过程内部被修改

2. **Pass By Value with Copy**：如果不想修改原数组，可以复制数组再传递：

Public Function ProcessCopyOfArray(arr() As Variant) As Variant
    Dim tempArray() As Variant
    ReDim tempArray(LBound(arr) To UBound(arr))
    tempArray = arr '创建了一个副本
    '...在这里处理tempArray...
    ProcessCopyOfArray = tempArray
End Function

Dim myArray(1 To 5) As Integer
Dim returnedArray() As Integer
returnedArray = ProcessCopyOfArray(myArray)

3. **使用数组初始化子范围**：如果函数返回新数组，可以在函数内部创建：

Public Function NewArrayWithData(arr() As Variant) As Variant()
    Dim newArray(sizeof(arr), 1) As Variant
    '...填充newArray...
    NewArrayWithData = newArray
End Function

Dim myArray(1 To 5) As Integer
Dim newArray() As Variant
newArray = NewArrayWithData(myArray)
