索引无法访问.Files集合：

>> Set oFiles = goFS.GetFolder(".\").Files
>> n = oFiles(0).Name
>>
Error Number:       5
Error Description:  Invalid procedure call or argument

您需要For Each循环来填充随机访问集合，例如一个数组：

>> Set oFiles = goFS.GetFolder(".\").Files
>> ReDim aFiles(oFiles.Count - 1)
>> i = 0
>> For Each oFile In oFiles
>>     Set aFiles(i) = oFile
>> Next
>> n = aFiles(0).Name
>> WScript.Echo n
