第二種:
復制代碼 代碼如下:
<% '定義函數，用ADODB.Stream讀取二進制數據 Function ReadBinaryFile(FileName) Const adTypeBinary = 1 Dim BinaryStream Set BinaryStream = CreateObject("ADODB.Stream") BinaryStream.Type = adTypeBinary BinaryStream.Open BinaryStream.LoadFromFile FileName ReadBinaryFile = BinaryStream.Read End Function Response.AddHeader "Content-Disposition", "attachment;filename=2.gif"'文件名 Response.ContentType = "image/GIF" '設置（1） response.Binarywrite ReadBinaryFile(server.mappath("2.gif"))'就是你讀取存在本地的文件，防止被 別人知道真實路徑盜連的。 %>
