求助 ASP.NET下载数据库中文件

Response.Buffer = true;

            Response.Clear();            Response.ContentType = "application/octet-stream";

            Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(file.FileName.ToString() + "." + file.FileType.ToString(), Encoding.UTF8));

            Response.AppendHeader("Content-Length", file.File.Length.ToString());

            Response.BinaryWrite((Byte[])file.File);

            Response.Flush();

            Response.End();

从数据库中读出byte类型的file.File,但是下载的文件保存到本地后,文本文档txt,world的内容是System.Byte[]
是什么原因啊..求解 --------------------编程问答-------------------- //以字符流的形式下载文件
            FileStream fs = new FileStream(filePath, FileMode.Open);
            byte[] bytes = new byte[(int)fs.Length];
            fs.Read(bytes, 0, bytes.Length);
            fs.Close();
            Response.ContentType = "application/octet-stream";
            Response.AddHeader("Content-Disposition", "attachment;   filename=" + HttpUtility.UrlEncode(fileName, System.Text.Encoding.UTF8));
            Response.BinaryWrite(bytes);
            Response.Flush();
            Response.End();

//以字符流的形式下载文件

这个我有用MemoryStream尝试过.

 byte[] bytes = new byte[file.File.Length];

            MemoryStream m = new MemoryStream(file.File);

            m.Read(bytes, 0, file.File.Length);

            m.Close();

            Response.Buffer = true;

            Response.Clear();            

            Response.ContentType = "application/octet-stream";

            Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(file.FileName.ToString() + "." + file.FileType.ToString(), Encoding.UTF8));

            Response.AppendHeader("Content-Length", file.File.Length.ToString());

            Response.BinaryWritebytes);

            Response.Flush();

            Response.End();

但是结果得到的文本的内容还是System.Byte[]

补充：.NET技术 ,  ASP.NET
