ASP.NET学习之页面传值(4)_Context传值

IndexPage.aspx页面：
必须在<form runat="server">中
<form runat="server">
        <div>
            <input id="Text1" type="text" runat="server"/>
            <input id="Text2" type="text" runat="server"/>
            <input id="Button1" value="传值" type="button" runat="server" onserverclick="ok_ServerClick"/>
        </div>
</form>

IndexPage.aspx.cs后台代码:
public void ok_ServerClick(object sender, EventArgs e)
        {
            //将要传递的值存放在Context中
            Context.Items["name"] = Text1.Value;
            Context.Items["pass"] = Text2.Value;
            //页面跳转
            Server.Transfer("ResultIndex.aspx");
        }
ResultPage.aspx.cs后台代码:
接收数据
protected void Page_Load(object sender, EventArgs e)
        {
            string name = Context.Items["name"].ToString();
            string pass = Context .Items["pass"].ToString();
            txt.Value = "用户名：" + name + "-----密码：" + pass; 
        }
