兄弟呀,你的下载方式不对呀!,应该这样:
在downloadadd.aspx中
sub page_load(sender as object, e as eventargs)
dim str as string=request("strfile")
dim file as system.io.fileinfo=new system.io.fileinfo(str)
response.clear()
response.addheader("content-disposition","attachment;filename=" + file.name)
response.addheader("content-length","file.length.tostring())
response.contenttype="application/octet-stream"
response.writefile(file.fullname)
response.end
end sub
