汗 NRModel.File model = new NRModel.File();
                                    NRBLL.File bf = new NRBLL.File();
                                    Guid guid1 = Guid.NewGuid();
                                    Guid guid2 = Guid.NewGuid();
                                    Guid guid3 = Guid.NewGuid();
                                    Guid guid4 = Guid.NewGuid();
                                    model.Fileid = guid1;
                                    model.Folderid = guid2;
                                    model.Filepath = strpath;
                                    model.FileNam = fileName.ToString();
                                    model.FileSize = postedFile.ContentLength;
                                    model.Decription = this.decrition.Value;
                                    model.CreateOn = DateTime.Now;
                                    model.CreateBy = guid3;
                                    model.ModefyBy = guid4;
                                    if (bf.FN_AddNewRes(model) > 0)
                                    {
                                        //fileExtension = Path.GetExtension(fileName);
                                        //strMsg.Append("上传的文件类型：" + postedFile.ContentType.ToString() + "<br>");
                                        //strMsg.Append("客户端文件地址：" + postedFile.FileName + "<br>");
                                        //strMsg.Append("上传文件的文件名：" + fileName + "<br>");
                                        //strMsg.Append("上传文件的扩展名：" + fileExtension + "<br>");
                                        //strMsg.Append("上传文件的大小：" + postedFile.ContentLength.ToString() + "个字节" + "<br>");
                                        postedFile.SaveAs(System.Web.HttpContext.Current.Request.MapPath("~/ResourcesFolder/") + fileName);
                                        Page.RegisterStartupScript("提示", "<script language='javascript'>alert('上传成功!')</script>");
                                        Response.Write("<script language='javascript'>self.opener.location.reload();</script>");
                                        Response.Write("<script language='javascript'>window.close();</script>");
                                    }这个就是保存服务器文件路径到数据库的

楼主可以看看这个jquery插件
http://www.cnblogs.com/oec2003/archive/2010/01/06/1640027.html

Answer 6

这个东西是好用，问题是不利于平台移植，我现在就是做个无脑版的，随时可以从一台服务器COPY到另外一台，啥都不用改的呵呵，所以只想要代码版的，插件版的暂时就不考虑了，不过还是谢谢楼上我再等等hebaobao19880921下午的回复吧，本来都做得差不多了，最后一个步骤总有点问题，可能脑筋一下没转过弯来进了死胡同，呵呵，所以求助一下，谢谢各位：）

Answer 7

model.Decription = this.decrition.Value;
这个字段就是描述 你需要更多的描述 增加字段继续添加就可以了 如果你的意思只是说增加字段的问题的话
