今天闲着无聊．想起来了ASP.NET身份验证．感觉良好．贴出下列代码:
login.aspx HTML代码

login.aspx.cs代码如下
private void btnLoginBetter_Click(object sender, System.EventArgs e)
{
if (this.tbName.Text == "admin" && this.tbPass.Text == "admin")
{
FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(1,this.tbName.Text,DateTime.Now,DateTime.Now.AddMinutes(30),this.PersistCookie.Checked,"User");//创建一个验证票据
string cookieStr = FormsAuthentication.Encrypt(ticket);进行加密
HttpCookie cookie = new HttpCookie(FormsAuthentication.FormsCookieName,cookieStr);创建一个cookie，cookie名为web.config设置的名,值为加密后的数据cookieStr,
if (this.PersistCookie.Checked)//判断用户是否选中保存cookie
cookie.Expires = ticket.Expiration;//获取cookie过期时间
cookie.Path = FormsAuthentication.FormsCookiePath;//设置cookie保存路径
Response.Cookies.Add(cookie);
string strRedirect;
strRedirect = Request["ReturnUrl"];//取出返回url
if (strRedirect == null)
strRedirect = "Default.aspx";
Response.Redirect(strRedirect,true);
}
else
{
Response.Write("<script>alert('帐号或密码错误!');self.location.href='02login.aspx'</script>");
}
}
