asp.net处理代码
private void get_history_log(HttpContext context)
{
string id = DTRequest.GetFormString("id_arr");
DataTable dt = new BLL.article().Getdata_List("housing", 5, "id in(" + id + ")", "sort_id asc").Tables[0];
var list = new List<object>();
for (int i = 0; i < dt.Rows.Count; i++)
{
DataRow dr = dt.Rows[i];
list.Add(new { id = dr["id"], title = dr["title"], price = dr["price"] });
}
context.Response.Write(new JavaScriptSerializer().Serialize(list));
return;
}
