flex通过HttpService与.net交互XML

客户端：

var hs:HTTPService=new HTTPService();  
                hs.url="http://localhost/test/Default.aspx";
    var parm:Object = {    
            }       

   hs.resultFormat="xml";
   hs.useProxy=false;

 hs.addEventListener(Event.RESULT,resultUsers);            
   hs.send(parm);

 

服务端：

接收客户端的参数：

Request.QueryString[""]—默认是get方式发送，

将datatable数据转换为xml反馈给客户端：

#region 将datatable转换为XML输出
//此datatable.writeXml方法导出的xml包含xml声明，flex可正确解析，绑定DataTable
                    Response.ContentType = "text/xml";
                    XmlTextWriter writer = new XmlTextWriter(Response.OutputStream, Response.ContentEncoding);
                    writer.Formatting = Formatting.Indented;
                    writer.Indentation = 4;
                    writer.IndentChar = ' ';
                    writer.WriteStartDocument();
                    dt.WriteXml(writer);
                    writer.Flush();
                    Response.End();
                    writer.Close();
  #endregion
