VBA 获取指定路径下指定类型文件的据对路径

Function Get_File_Path_Arr(Path_String As String, File_type As String, File_Qty As Integer)
    Dim This_File_Path As String

    Dim File_Down As Integer
    File_Down = 0
      
    ReDim Arr(File_Qty) As String
    
    This_File_Path = Dir(Path_String & File_type)
    
    File_Down = File_Down + 1
    Arr(File_Down) = Path_String & This_File_Path
      
    Do While This_File_Path <> ""
        This_File_Path = Dir
        If This_File_Path = "" Then
            Exit Do
        End If
        File_Down = File_Down + 1
        Arr(File_Down) = Path_String & This_File_Path
    Loop
    Get_File_Path_Arr = Arr
End Function

可以直接调用调用获取数量
Function Get_File_Count(Path_String As String, File_type As String) As Integer
    Dim This_File_Path As String
    Dim File_Counts As Integer
    File_Counts = 0
    This_File_Path = Dir(Path_String & File_type)
    
    Do While This_File_Path <> ""
        File_Counts = File_Counts + 1
        This_File_Path = Dir
    Loop
    Get_File_Count = File_Counts
End Function
