积少成多Flash(3) - ActionScript 3.0 基础之以文本形式、XML形式和JSON形式与ASP.NET通信

作者：webabcd


介绍
Flash ActionScript 3.0 以文本形式与ASP.NET通信、以XML形式与ASP.NET通信和以JSON形式与ASP.NET通信


示例
Text.aspx.cs

using System;
using System.Data;
using System.Configuration;

using System.Web.UI.HtmlControls;

public partial class Text : System.Web.UI.Page
{
        protected void Page_Load(object sender, EventArgs e)
        {
                string s = "name: " + Request.QueryString["name"] + "; age: " + Request.QueryString["age"];

                Response.ClearContent();
                Response.ContentType = "text/plain";
                Response.Write(s);
                Response.End();
        }
}
