推荐答案

好吧，看来您正在下载到本地文件系统.如果文件在数据库中，则需要将其拉出并使用Response.BinaryWrite而不是Response.TransmitFile来将其写入流中.

Well, it looks like you''re downloading TO the local file system. If your file is inside a DB, you need to pull it out and use Response.BinaryWrite instead of Response.TransmitFile to write it to the stream.
