我无法在启动时将自定义保存ConfigurationSection在我的web.config文件中。

我已经按照本教程进行了通用实现。我的单元测试通过了，我可以ConfigurationSection在单元测试中保存 de！

在应用程序启动时，我想ClaimCollection基于控制器类名和所属方法名构建一个：

启动.cs

public void Configuration(IAppBuilder app)
{

    Config = new HttpConfiguration();

    BuildUnityContainer();

    BuildClaimCollection(); <----------------

    ConfigureOAuth(app);

    WebApiConfig.Register(Config);
    app.UseCors(Microsoft.Owin.Cors.CorsOptions.AllowAll);
    app.UseWebApi(Config);

}

public void BuildClaimCollection()
{

    //config section
    MethodClaimSection methodClaimSection = BaseConfigurationSection<MethodClaimSection>.Open();

    var methods = GetClaimAuthorizedMethods();

    foreach (var method in methods)
    {
        var claimValue = GetClaimValueFromMethodName(method);
        var claim = new MethodClaimElement()
        {
            Type = "Method",
            Value = claimValue
        };

        methodClaimSection.MethodClaims.Add(claim);
    }
    methodClaimSection.Save();
}

BaseConfigurationSection.cs 

public abstract class BaseConfigurationSection<T> : ConfigurationSection
             where T : ConfigurationSection, new()
{
    public void Save()
    {
        System.Configuration.Configuration config = BaseConfigurationSection<T>.GetConfiguration();
        T section = (T)config.Sections[typeof(T).Name];

        foreach (var property in this.GetType().GetProperties())
        {
            if (property.IsDefined(typeof(ConfigurationPropertyAttribute), false))
            {
                section.GetType().InvokeMember(property.Name, BindingFlags.SetProperty, null, section, 
                    new object[] { 
                        .GetType().InvokeMember(property.Name, BindingFlags.GetProperty, null, this, null) 
                        });
            }
        }

        config.Save(ConfigurationSaveMode.Full);
    }
}

当我运行 WebApi 应用程序时，我收到此错误：

无法访问已处置的对象。对象名称：'System.Web.Http.HttpServer'。

堆栈跟踪：

[ObjectDisposedException：无法访问已处置的对象。对象名称：'System.Web.Http.HttpServer'。] System.Net.Http.DelegatingHandler.CheckDisposed() +332772 System.Net.Http.DelegatingHandler.CheckDisposedOrStarted() +13 System.Net.Http.DelegatingHandler.set_InnerHandler( HttpMessageHandler value) +23 System.Web.Http.HttpServer.Initialize() +108 System.Web.Http.HttpServer.b__b() +31 System.Threading.LazyInitializer.EnsureInitializedCore(T& target, Boolean& initialized, Object& syncLock, Func` 1 valueFactory) +115 System.Threading.LazyInitializer.EnsureInitialized(T& target, Boolean& initialized, Object& syncLock, Func`1 valueFactory) +72 System.Web.Http.HttpServer.EnsureInitialized() +119 System.Web.Http.d__0。

Configuration 类没有 Dispose 方法...

如何解决这个问题呢？
