asp.net读取与写入cookie的实例

C#实现的读取与写入cookie的例子。

代码如下：

protected void Page_Load(object sender, EventArgs e)

{
    //打开登录页面时获取客户端cookie值并写入前台控件中
    HttpCookie cookie = Request.Cookies["name"];
    if (cookie == null)
    {
      UserName.Text = "";
    }
    else
    {
       UserName.Text = cookie.Value;
    }
}
 
protected void btnSubmit_Click(object sender, EventArgs e)
{
    string username = Request.QueryString["UserName"];
    string password = Request.QueryString["PassWord"];
    if (登录成功)
    {
       Response.Write("登陆成功"); //www.jbxue.com
       HttpCookie cookie=new HttpCookie("name",username);//获取用户的用户名
       cookie.Expires = DateTime.Now.AddDays(10);//设置cookie过期时间为10天后
       Response.Cookies.Add(cookie);//将cookie写入客户端
    }
    else
    {
        Response.Write("登陆失败");
    }
}
