1.配置系统文件web.config

<system.web>
<authentication mode="Forms" >
  <forms name=".yaoCookies"

        loginUrl="login.aspx"

        protection="All"
        timeout="20"

        path="/" />
 </authentication>

指定拒绝或者准许的用户或者角色,详细请参考MSDN上介绍

 <authorization>

          <allow users="*" />
           <deny users="?" />
  </authorization>
</system.web>

?/P> 2.登录页

//登录按钮
private void Button1_Click(object sender, System.EventArgs e)
{
       
//实体类AdminUserVO对应AdminUser用户表。
    AdminUserVO adminUserVO = new AdminUserVO();
    adminUserVO.Uname = UserName.Text.Trim();
    adminUserVO.Upwd = UserPwd.Text.Trim();
    adminUserVO.LastIP = HttpContext.Current.Request.UserHostAddress;
    adminUserVO.LastTime = DateTime.Now;
    
bool flag = (new LoginDAO()).Chk(adminUserVO);


     
if (flag)
      {
        
//非角色验证时:
        System.Web.Security.FormsAuthentication.SetAuthCookie(UserName.Text.Trim(),false);

        string requestUrl = FormsAuthentication.GetRedirectUrl(FormsAuthentication.FormsCookieName,false);
       //创建角色验证信息,role信息写入到UserData

       //见基于角色的Forms认证步骤

       //SetLoginCookie(adminUserVO,adminUserVO.Roles.ToLower());
       HttpContext.Current.Response.Redirect(requestUrl);
       }
       
else
       {
         HttpContext.Current.Response.Write("
登录失败");
       }
}
