byte[] filedata = (byte[])ds.Tables[0].Rows[0]["filedata"];
然后用下面的语句显示
Response.ContentType="application/msword";
Response.AddHeader("Content-Disposition", "inline;filename=" + Server.UrlEncode(filename).Replace("+"," "));
Response.BinaryWrite(filedata);
Response.End();

 

    if(dr["doctype"].ToString()=="application/msword")
    {
     Response.ContentType = "application/msword";
    }
    else
    {
     Response.ContentType = "application/vnd.ms-excel";
    }
    Response.AddHeader("Content-Disposition", dr["doctitle"].ToString());
    Response.Flush();
    Response.BinaryWrite((byte[])dr["doctext"]);
    Response.End();

 

public void ToWord(System.Web.UI.Control ctl) 
  {
   HttpContext.Current.Response.AppendHeader("Content-Disposition","attachment;filename=1.doc");

   ctl.RenderControl(hw);
   HttpContext.Current.Response.Write(tw.ToString());
   HttpContext.Current.Response.End();
  }

 Response.Clear();
