C#实现百度ping功能

网站优化必做的事情之一，百度ping，主动推送给百度

文章添加时调用百度推送方法

        //保存
        protected void btnSubmit_Click(object sender, EventArgs e)
        {
            if (action == DTEnums.ActionEnum.Edit.ToString()) //修改
            {
                ChkAdminLevel("channel_" + this.channel_name + "_list", DTEnums.ActionEnum.Edit.ToString()); //检查权限
                if (!DoEdit(this.id))
                {
                    JscriptMsg("保存过程中发生错误啦！", string.Empty);
                    return;
                }
                JscriptMsg("修改信息成功！", "article_list.aspx?channel_id=" + this.channel_id);
            }
            else //添加
            {
                ChkAdminLevel("channel_" + this.channel_name + "_list", DTEnums.ActionEnum.Add.ToString()); //检查权限
                int id=DoAdd();  //此  id为添加文章返回的 此篇文章的id 需要修改添加文章的方法  返回id if (!(id>0))
                {
                    JscriptMsg("保存过程中发生错误！", string.Empty);
                    return;
                }
                //获取频道模板名称
                if (channel_id == 13 || channel_id == 16 || channel_id == 18 || channel_id == 25 || channel_id == 6)
                {
                    string channelTemp = new BLL.channel().GetModel(this.channel_id).name.ToString();
                    string articleUrl = new BasePage().linkurl(channelTemp + "_show", id);
                    string[] url = new string[100];
                    url[1] = "http://www.qishunnet.com" + articleUrl;//例如生成的url如http://www.qishunnet.com/knowledge_show_132.html
                    string info = DTcms.Common.BaiDu.sendUrlToBaidu(url);
                    JscriptMsg("添加信息成功！", "article_list.aspx?channel_id=" + this.channel_id + "&message=添加信息成功！百度推送返回信息=" + info + "url：" + url[1]);
                    return;
                }
                JscriptMsg("添加信息成功！", "article_list.aspx?channel_id=" + this.channel_id);
            }
        }
