用于成员身份角色授权的Web.config编辑

我想通过web.config文件中的授权部分来使用基于角色的安全性.

使用Membership,我的应用程序将允许创建新角色,因此,他们可以访问的页面需要动态设置.

我可以以编程方式更改web.config中的此部分来管理它吗？如果是这样,怎么样？

using System.Configuration;
using System.Web.Configuration;

Configuration config = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
AuthorizationSection section = (AuthorizationSection)config.GetSection("system.web/authorization");

AuthorizationRule rule = new AuthorizationRule(AuthorizationRuleAction.Allow);
rule.Roles.Add("admins");
section.Rules.Add(rule);

config.Save();

Imports System.Configuration
Imports System.Web.Configuration

Dim config As Configuration = WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath)
Dim section As AuthorizationSection = CType(config.GetSection("system.web/authorization"), AuthorizationSection)

Dim rule As New AuthorizationRule(AuthorizationRuleAction.Allow)
rule.Roles.Add("admins")
section.Rules.Add(rule)

config.Save()

ASP.NET需要web.config写权限才能工作,所以要小心.
