表单验证

在用ASP.NET做WEB开发时,一般可以用FORM验证,它使用起来相对简单,也可以提升自己网站的安全性,下面是初学代码.请各位大侠多多指教.

 1<configuration>
 2   <system.web>
 3      <authentication mode = "Forms">
 4         <forms name="ProgAspNetCookie" loginUrl="csLoginForm.aspx" />
 5      </authentication>
 6
 7      <authorization>
 8         <deny users="?" />
 9      </authorization>
10   </system.web>
11</configuration>

这里是DEMO页面

 1<%@ Page Language="vb" %>
 2<script runat="server">
 3   Sub btn_Click()sub btn_Click(ByVal Sender as Object, _
 4                 ByVal e as EventArgs)
 5      if FormsAuthentication.Authenticate(txtUserName.Text, _
 6                                          txtPassword.Text) then
 7         FormsAuthentication.RedirectFromLoginPage(txtUserName.Text, _
 8                                                   false)
