c# - 我如何在 Web 应用程序中使用配置文件

Question

我从网站转移到 Web 应用程序以改进它，我的网站上有个人资料。

我的配置文件不起作用，所以我实现了 System.Web.ProfileProvider 并创建了一个类 ProfileCommon 继承 ProfileBase 我使用 HttpContext.Current.Profile.SetPropertyValue 和 GetPropertyValue。它有效，但问题是它有一个逻辑错误，因为 HttpContext.Current.Profile 没有调用我的 ProfileProvider 方法我该如何修复它？或者在 Web 应用程序中是否有任何其他配置文件实现？

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

在 web.config 中

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

您是否尝试过在 web.config 中添加 enabled="true"？

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