我正在尝试通过使用计算机名称操作当前路径来将当前共享文件夹路径转换为 unc 路径。但是会导致编译错误：公共函数 UNCpath() 中的“elem = UBound(CurrentPathA)”行上存在预期数组。你们能告诉我造成这个问题的原因是什么吗？也许分享更好的想法来获得 unc 路径？
Option Explicit
#If VBA7 Then
Private Declare PtrSafe Function fnGetComputerName Lib "kernel32" Alias "GetComputerNameW" (ByVal lpBuffer As LongPtr, ByRef nSize As Long) As Long
#Else
Private Declare Function fnGetComputerName Lib "kernel32" Alias "GetComputerNameW" (ByVal lpBuffer As Long, ByRef nSize As Long) As Long
#End If
Public Function GetComputerName() As String
Const MAX_COMPUTERNAME_LENGTH As Long = 31
Dim buf As String, buf_len As Long
buf = String$(MAX_COMPUTERNAME_LENGTH + 1, 0)
buf_len = Len(buf)
If (fnGetComputerName(StrPtr(buf), buf_len)) = 0 Then
GetComputerName = "ErrorGettingComputerName"
Else
GetComputerName = Left$(buf, buf_len)
End If
End Function
Public Function UNCpath() As String
Dim CompName As String, CurrentPath As String, CurrentPathA As String
CompName = GetComputerName()
CurrentPath = ThisWorkbook.Path
CurrentPathA = Split(CurrentPath, "\")
elem = UBound(CurrentPathA)
CurrentPath = CurrentPathA(elem)
UNCpath = "\\" & CompName & "\" & CurrentPath
End Function
或者使用文件系统对象：
Function GetUNCLateBound(strMappedDrive As String) As String
Dim objFso As Object
Set objFso = CreateObject("Scripting.FileSystemObject")
Dim strDrive As String
Dim strShare As String
'Separate the mapped letter from
'any following sub-folders
strDrive = objFso.GetDriveName(strMappedDrive)
'find the UNC share name from the mapped letter
strShare = objFso.Drives(strDrive & "\").ShareName
'The Replace function allows for sub-folders
'of the mapped drive
GetUNCLateBound = Replace(strMappedDrive, strDrive, strShare)
Set objFso = Nothing 'Destroy the object
End Function
我刚刚发现并修改了这个，这是应得的，是后期绑定的：
