打开或者另存为文件问题

Question

我的数据表是这样的
ID   File
1    a.doc
2    ab.doc
3    x.doc
......文件都是存在d:\wen\下的，请问大家怎么能显示成这样
序列号 文件
1    a.doc
2    ab.doc
3    x.doc用户点击a.doc等文件名后就可以打开或者另存为此doc文件

Answer 1

<a href="" ><%#Eval("File")%></a>

Answer 2

Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition","attachment; filename=abc.doc");//以附件形式打開 也就是彈出對話框
Response.AddHeader("Content-Disposition","inline; filename=abc.doc");//在線打開

Answer 3

5楼的兄弟，我的文件都是存在d:\wen\下的，我看你给的代码里面没有显示文件路径呀

Answer 4

你把要下载的文件转换成流bytes[] b = 文件流转换的字节数;
Response.OutputStream.Write(b , 0, b.Length);
Response.Flush();

Answer 5

 string fileName = Request.QueryString["fileName"].ToString();
            string filePath = Server.MapPath("~/Upload/UploadFile/") + fileName;
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath);
            if (fileInfo.Exists == true)
            {
                string[] fileNameSplit = fileName.Split('_');
                string myFileName=null;
                for (int i = 1; i < fileNameSplit.Length; i++)
                {
                    myFileName +=fileNameSplit[i];
                }
                const long ChunkSize = 102400;//100K 每次读取文件，只读取100K，这样可以缓解服务器的压力
                byte[] buffer = new byte[ChunkSize];
                Response.Clear();
                try
                {
                    System.IO.FileStream iStream = System.IO.File.OpenRead(filePath);
                    long dataLengthToRead = iStream.Length;//获取下载的文件总大小
                    Response.ContentType = "application/octet-stream";
                    Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(myFileName));
                    while (dataLengthToRead > 0 && Response.IsClientConnected)
                    {
                        int lengthRead = iStream.Read(buffer, 0, Convert.ToInt32(ChunkSize));//读取的大小
                        Response.OutputStream.Write(buffer, 0, lengthRead);
                        Response.Flush();
                        dataLengthToRead = dataLengthToRead - lengthRead;
                    }
                }
                catch (Exception ex)
                {
                    string error = ex.ToString();
                }
                finally
                {
                    Response.Close();
                }
            }写一个方法需要参数为fileName,放在一个页面(download)的PageLoad里，将XXX.DOC做成一个超链接，利用URL传值给(download)传去fileName即可
