下载 问题

Question

这是代码
string musicURL=reader1.GetString(0);
 musicURL是文件的相对路径，以musicURL="flv/2.wmv"为例；
怎么加代码在下面，才能实现下载功能
         
//Response.Redirect( musicURL);删
Response.ContentType = "application/octet-stream";
        Response.AddHeader("Content-Disposition", "attachment;FileName="+musicURL);
        Response.BinaryWrite();
        Response.End();

    public void DownloadExcelFile(string musicURL,string FName )
    {
        if (musicURL!= "" && musicURL!= null)
        {
            System.IO.FileInfo file = new System.IO.FileInfo(AppDomain.CurrentDomain.BaseDirectory + musicURL);
            if (file.Exists)
            {
                string ExtendName = file.Name;
                if (ExtendName.Length > 4)
                {
                    string FileName =FName ;
                    int i = ExtendName.LastIndexOf(".");
                    ExtendName = ExtendName.Substring(i);
                    FileName += ExtendName;
                }
                HttpContext.Current.Response.Clear();
                HttpContext.Current.Response.AddHeader("Content-Disposition", "attachment;                 
                filename=" + HttpUtility.UrlEncode(FileName, System.Text.Encoding.UTF8));
                HttpContext.Current.Response.AddHeader("Content-Length", file.Length.ToString());
                HttpContext.Current.Response.ContentType = "application/octet-stream";
                HttpContext.Current.Response.Filter.Close();
                HttpContext.Current.Response.WriteFile(file.FullName);
                HttpContext.Current.Response.End();
            }
            else
            {
                HttpContext.Current.Response.Write("对不起,文件" + AppDomain.CurrentDomain.BaseDirectory + fileName + "不存在");
            }
        }
    }
