int id = Convert.ToInt32(context.Request.QueryString["id"]);
IPukeInfoImageBLL puekeInfoImageBLL = new PukeInfoImageBLL();
string xmlstr = "[";
PukeInfoImage InfoImage = puekeInfoImageBLL.getPukeInfoByPukeID(id);
//DataContractJsonSerializer djson = new DataContractJsonSerializer(InfoImage.GetType());
xmlstr += "{id:'" + InfoImage.ID + "',userid:'" + InfoImage.UserID + "',imageName:'" + InfoImage.ImageName + "',textinfo:'" + InfoImage.TextInfo + "',datetime:'" + InfoImage.PublishDate + "',publish_type_id:'" + InfoImage.InfoPublishTypeID + "',remark:'" + InfoImage.Remark + "'},";
xmlstr = xmlstr.Remove(xmlstr.Length - 1);
xmlstr += "]";
context.Response.Write(xmlstr);
