我想为一块文件找到一个哈希并将该哈希保存在另一个文件中。我想直接这样做，而不必将块保存在单独的文件中。这是我的程序。

 Const chunksize = 1024000000
 dim istream,ostream
  Sub WriteChunk(data)
   Set oStream = CreateObject("ADODB.Stream")
   oStream.Open
   oStream.Type = 1 
   oStream.Write data

   Dim WshShell, oExec, input,objfile2,str1
   Set WshShell = CreateObject("WScript.Shell")
   Set oExec    = WshShell.exec("C:\Users\Administrator\desktop\experimenting\md5.exe_
                             -odup5.txt """ & ostream.write & """")

   input = ""
      Do While oexec.status=0
     WScript.Sleep 50
     Loop
     oStream.Close
   End Sub

    Set iStream = CreateObject("ADODB.Stream")
     iStream.Open
   iStream.Type = 1  'binary
    Const FOR_READING = 1

     strFolder = "C:\test" 

     Set objFSO = CreateObject("Scripting.FileSystemObject")

     Set objFolder = objFSO.GetFolder(strFolder)

     Set colFiles = objFolder.Files

     For Each objFile In colFiles
      iStream.LoadFromFile objfile.path
        Do Until istream.EOS
      WriteChunk iStream.Read(chunksize)


      loop 


     Next

     ShowSubFolders(objFolder)


   Sub ShowSubFolders(objFolder)

   Set colFolders = objFolder.SubFolders

       For Each objSubFolder In colFolders

      set colFiles = objSubFolder.Files

      For Each objFile2 In colFiles


      iStream.LoadFromFile objfile2.path
      Do Until istream.EOS
      WriteChunk iStream.Read(chunksize)



        loop 
        Next

        ShowSubFolders(objSubFolder)

       Next

     End Sub


       iStream.Close

ostream.write 不能用作参数。但我不明白什么可以代替那个..请帮助

Set oExec = WshShell.exec("C:\Users\Administrator\desktop\experimenting\md5.exe_
                     -odup5.txt """ & ostream.write & """")

以上将失败，因为您不能在字符串中使用换行。此外，ostream.write意味着您正在尝试向 ADODB Stream 对象写入内容。你真正想做的（假设我正确理解了你的问题并且你正在使用这个 md5.exe）是这样的：

WshShell.Run "C:\...\md5.exe -ochunk_md5.txt -d""" & data & """"

要将所有数据块的结果写入同一个文件，请执行以下操作：

WshShell.Run "%COMSPEC% /c md5.exe -o- -d""" & data & """>chunk_md5.txt", 1, True

或像这样：

Set md5 = WshShell.Exec("md5.exe -o- -d""" & data & """")
Do While md5.Status = 0
  WScript.Sleep 100
Loop
objFSO.OpenTextFile("chunk_md5.txt", 8, True).Write md5.StdOut.ReadAll

或者，您可以使用此 VBScript计算哈希并将结果写入文件。
