下载：

string strFileName = Server.UrlDecode(Server.UrlDecode(FileName));
                    Response.AppendHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(strFileName));
                    Response.ContentType = "application/force-download";
                    if (System.IO.File.Exists(strFilePath + strFileName))
                    {
                        BM1.IBLL.IFileViewBLL bll = BM1.Factory.BLLFactory.CreateIFileViewBLL();
                        ArrayList list = bll.Document(Session["CMP_ID"].ToString(), FileName.Split('.')[FileName.Split('.').Length-2].ToString(),Convert.ToDateTime(DG1.Items[i].Cells[4].Text));
                        foreach (object obj in list)
                        {
                            FileRgstVO fr = (FileRgstVO)obj;
                            bll.Down_Rec(Session["CMP_ID"].ToString(), Session["USER_ID"].ToString(), System.DateTime.Now, FileName.Split('.')[FileName.Split('.').Length - 2].ToString(),fr.GetVersion_No,fr.GetPath,fr.GetType,fr.GetRemark);
                        }

                        Response.WriteFile(strFilePath + strFileName);
                        Response.End();

上传：

    private void UploadFile(string To_Path) //上传文件
    {
        string path = To_Path + Request.Form["Tbx_FileName"].ToString()+"."+ Request.Form["TbxName"].ToString();
        if (File.PostedFile.ContentLength != 0)
        {           
            File.PostedFile.SaveAs(path);
        }
