ASP.NET WEB——项目中Cookie与Session的用法

<asp:TextBox runat="server" ID="userName" placeholder="cookie值"></asp:TextBox>
<hr />
<asp:Button runat="server" OnClick="Unnamed_Click" Text="存储Cookie"/>
<hr />
获取Cookie：<asp:Label runat="server" ID="show"></asp:Label>

protected void Unnamed_Click(object sender, EventArgs e)
{
    //创建Cookie
    HttpCookie cookie = new HttpCookie("userName");
    //设置值
    cookie.Value = this.userName.Text;
    //这个设置过期时间的
    cookie.Expires = DateTime.MaxValue;
    //添加到Cookie中
    Response.Cookies.Add(cookie);
    //直接获取
    this.show.Text = Response.Cookies["userName"].Value;
}

<asp:TextBox runat="server" ID="userName" placeholder="Session值"></asp:TextBox>
<hr />
<asp:Button runat="server" OnClick="Unnamed_Click" Text="存储Session" />
<hr />
获取Session：<asp:Label runat="server" ID="show"></asp:Label>

protected void Unnamed_Click(object sender, EventArgs e)
{
    //存储session
    Session["userName"] = this.userName.Text;
    //获取Session
    this.show.Text = Session["userName"].ToString();
}
