Answer 1

大致如下,請參考:FileStream fs = new FileStream("絕對路徑", FileMode.Open, FileAccess.Read);
BinaryReader r= new BinaryReader(fs);
Response.Buffer=true;
Response.AddHeader("Content-Disposition", "attachment; filename=文件名");
Response.Charset = "GB2312";
Response.ContentType = "application/octet-stream";
Response.BinaryWrite(r.ReadBytes(Convert.ToInt32(fs.Length)));
Response.Flush() ;

Answer 3

试试这个
        
        string createPath = Server.MapPath("../" + FilePath);//FilePath服务器上文件相对路径
        FileInfo DownloadFile = new FileInfo(createPath);
        Response.Clear();
        Response.ClearHeaders();
        Response.Buffer = true;
        Response.ContentType = "application/octet-stream";
        Response.AddHeader("Content-Disposition", "attachment;filename=" + Server.UrlEncode(FileName));//FileName带扩展名的文件名
        Response.AddHeader("Content-Length ", DownloadFile.Length.ToString());
        Response.TransmitFile(createPath);
        Response.Flush();
        Response.End();
