Session的存取删
首先创建ASP.NET空窗体然后建立web窗体分别建立两个如下SessionChildDemo.aspx SessionDemo.aspx
先看SessionChildDemo.aspx前台的代码如下
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SessionChildDemo.aspx.cs" Inherits="SessionChildDemo" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title></title>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:Button ID="Button1" runat="server" Text="取" OnClick="Button1_Click" />
</div>
</form>
</body>
</html>
后台的代码如下
protected void Button1_Click(object sender, EventArgs e)
{
Response.Write(Session["Title"]);
}
SessionDemo.aspx页面的前台代码如下
<body>
<form id="form1" runat="server">
<div>
<p>
<asp:Button ID="Button1" runat="server" Text="存" OnClick="Button1_Click" /></p>
<p>
<asp:Button ID="Button2" runat="server" Text="取" OnClick="Button2_Click" /></p>
<p>
<asp:Button ID="Button3" runat="server" Text="删" OnClick="Button3_Click" /></p>
</div>
</form>
</body>
后台的代码如下
public partial class SessionDemo : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
//存
Session["Title"] = "HelloWord";//声明一个session名称叫做Title 将hello Word内容赋给session
Session["Student"] = 1;
}
protected void Button2_Click(object sender, EventArgs e)
{
string content = Session["Title"].ToString();
Response.Write(content);
}
protected void Button3_Click(object sender, EventArgs e)
{
//清除整个网站的session
Session.Clear();
//清除某一个session根据名称
// Session.Remove("Title");
}
}
