HttpResponse..::.BinaryWrite 方法将一个二进制字符串写入 HTTP 输出流。

下面的示例将一个文本文件读入缓冲区，然后将该缓冲区写入 HTTP 输出流。

FileStream MyFileStream;
long FileSize;

MyFileStream = new FileStream("sometext.txt", FileMode.Open);
FileSize = MyFileStream.Length;

byte[] Buffer = new byte[(int)FileSize];
MyFileStream.Read(Buffer, 0, (int)FileSize);
MyFileStream.Close();

Response.Write("<b>File Contents: </b>");
Response.BinaryWrite(Buffer);

asp文件下载改名

Response.ContentType = "application/x-msexcel"
Response.AddHeader "Content-Disposition","attachment; filename=aa.xls"
Const adTypeBinary = 1
Dim strFilePath

Set objStream = Server.CreateObject("ADODB.Stream")
objStream.Open
objStream.Type = adTypeBinary
objStream.LoadFromFile Trim(sfile)

Response.BinaryWrite objStream.Read

objStream.Close
Set objStream = Nothing
HttpResponse = true
