我在VB.NET中创建了一个DLL文件,我希望在Excel VBA中使用它。当我像一个函数一样使用它时,它工作得很完美,但当我使用带有ByRef
变量的sub时,它不起作用,Excel重新启动并出现错误。
VB.NET中的代码是:
Public Function distinctArr(ByVal arr As String()) As String()
Return arr.ToList.Distinct.ToArray
End Function
Public Sub sortArr(ByVal arr As String(), ByRef a As String())
Dim tolist As List(Of String) = arr.ToList
tolist.Sort()
a = tolist.ToArray
End Sub
这是VBA中的代码:
Dim objMda As Excelcode.mda
Set objMda = New Excelcode.mda
Dim distinc_Item() As String
Dim all_Items() As String
all_Items = rng_to_string(rng_rizmetre)
distinc_Item = objMda.distinctArr(all_Items) '''This line is working perfect
Dim Sorted_Item() As String
objMda.sortArr distinc_Item, Sorted_Item
代码有什么问题?
答案 0 :(得分:1)
最后我能找到答案。 vb.net中的代码
Public Class MainClass
Sub sortArr(ByVal arr As String(), ByRef sortedarr As String())
sortedarr = arr
Array.Sort(sortedarr)
End Sub
End Class
和excel vba中的代码:
Sub aaa()
Dim Mycode As excelcode.MainClass
Set Mycode = New excelcode.MainClass
Dim arr(2) As String
arr(0) = "m"
arr(1) = "a"
arr(2) = "d"
Dim sortedArr() As String
ReDim sortedArr(0)
Mycode.sortArr arr, sortedArr
End Sub
通过这段代码我可以将数组byval传递给vb.net dll然后vb.net传递排序数组。
