如何在Web应用程序中使用配置文件

I moved to web application from web site to improve it, I have profile in my web site.

我从网站转移到Web应用程序来改进它，我在我的网站上有个人资料。

My profile didn't work, so I implement System.Web.ProfileProvider and create a class ProfileCommon inherit ProfileBase I use HttpContext.Current.Profile.SetPropertyValue and GetPropertyValue. it works but the problem is it has a logically bug because HttpContext.Current.Profile doesn't call my ProfileProvider method How I can repair this ? or maybe is there any other implementation for profile in web application ?

我的配置文件不起作用，所以我实现System.Web.ProfileProvider并创建一个类ProfileCommon继承ProfileBase我使用HttpContext.Current.Profile.SetPropertyValue和GetPropertyValue。它的工作原理，但问题是它有一个逻辑错误，因为HttpContext.Current.Profile不会调用我的ProfileProvider方法我怎么能修复它？或者在Web应用程序中是否有任何其他的配置文件实现？

    public class ProfileCommon : ProfileBase
{
    public string FirstName 
    {
        get
        {
            return HttpContext.Current.Profile.GetPropertyValue("FirstName").ToString();
        }
        set
        {
            HttpContext.Current.Profile.SetPropertyValue("FirstName", value);
        }
    }
}

in the web.config

在web.config中

<profile inherits="BaniBookWebApp.Code.Core.ProfileCommon">
  <providers>
    <add name="CustomProfileProvider" type="BaniBookWebApp.Code.Core.CustomProfileProvider"/> 
  </providers>     
</profile>

CustomProfileProvider :

have you tried adding enabled="true" on the web.config?

你试过在web.config上添加enabled =“true”吗？

<profile inherits="BaniBookWebApp.Code.Core.ProfileCommon" enabled="true">
