Exit Sub
end if
binRequestData=Request.BinaryRead(lngRequestSize)
binForm.Type = 1
binForm.Open
binForm.Write binRequestData 这是错误提示行

Dim bCrLf,strSeparator,intSeparator
bCrLf=ChrB(13)&ChrB(10)

intSeparator=InstrB(1,binRequestData,bCrLf)-1
strSeparator=LeftB(binRequestData,intSeparator)

------解决方案--------------------
binForm.Type = 1
binForm.Mode = 2
