取数据AutoComplete.aspx前台代码只需要一句：

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="AutoComplete.aspx.cs" Inherits="GDC.CQMS.Web.UserControlsV4.PreCQ.AutoComplete" %>

后台代码：

 protected void Page_Load(object sender, EventArgs e)
        {
            string q = Request["q"].ToString();
            //List<string> list = new List<string>();
            string rlt = string.Empty;
            DataTable dt = prjsrv.GetCustomizedField(q);
            Response.Clear();
            Response.Charset = "UTF-8";
            Response.ContentEncoding = System.Text.Encoding.UTF8;
            Response.ContentType = "text/xml";
            Response.Write("<?xml version='1.0' encoding='utf-8'?>");
            Response.Write("<ArrayOfString xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns='http://tempuri.org/'>");
            string template = "{{value:'{0}',n:'{1}'}}" + System.Environment.NewLine;//+”\n”
            if (dt != null && dt.Rows.Count > 0)
            {
                foreach (DataRow dr in dt.Rows)
                {
                    rlt = "<string>" + string.Format(template, dr["CustomizedField"].ToString(), "n") + "</string>";
                    Response.Write(rlt);  
                }
            }

            Response.Write("</ArrayOfString>");  
            Response.Flush();
            Response.End();
        }
