问题描述

我只是工作与FormsAuthentication，我想形式的认证标签的web配置超时属性的值。在4.0，我们可以通过FormsAuthentication.Timeout.TotalMinutes（得到这个编号：<一href="http://stackoverflow.com/questions/5171637/formsauthenticationticket-expiration-v-web-config-value-timeout">FormsAuthenticationTicket.expiration v web.config中值超时），你可以让我知道我怎样才能在.NET 2.0一样的吗？

I was just working with FormsAuthentication and I wanted the value of timeout property of form authentication tag in web config. In 4.0 we can get this via FormsAuthentication.Timeout.TotalMinutes (ref: FormsAuthenticationTicket.expiration v web.config value timeout) Can you let me know how can I get the same in .NET 2.0?

推荐答案

看看<一href="https://connect.microsoft.com/VisualStudio/feedback/details/102290/expose-forms-authentication-timeout-as-a-public-static-property">this问题在微软Connect网站。它被关闭，不会修复，但它看起来像它被固定在.NET 4中。

Take a look at this issue on Microsoft's Connect site. It was closed as "Won't Fix", but it looks like it's been fixed in .NET 4.

一做在.NET 2.0或3.x版的方式是发行和检查一个FormsAuthentication票：

One way of doing it in .NET 2.0 or 3.x is to issue and inspect a FormsAuthentication ticket:

FormsAuthentication.SetAuthCookie("user", false);
HttpCookie cookie = (HttpCookie)(Request.Cookies[FormsAuthentication.FormsCookieName]);
FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(cookie.Value);
int timeoutInMinutes = (ticket.Expiration - ticket.IssueDate).TotalMinutes; 

另一种是使用配置API：

Another is to use the configuration APIs:

Configuration config = Configuration.OpenWebConfiguration(HttpRuntime.AppDomainAppPath);
AuthenticationSection section = 
    (AuthenticationSection)config.GetSection("system.web/authentication");
int timeout = section.Forms.Timeout.TotalMinutes;
