Server.Transfer传值方法的使用

Default1：    protected void Button1_Click(object sender, EventArgs e)    {        string Str = "Hello World";        this.Context.Items.Add("Text",Str);        this.Server.Transfer("default2.aspx");    }     Default2：    protected void Page_Load(object sender, EventArgs e)    {        this.Response.Write(this.Context.Items["Text"].ToString());//HttpContext接收数据    }
