第一次调用 GetInstance、GetAllInstances、Verify 和 GetRegistration 的一些调用后容器不能改变

Question

我无法弄清楚为什么在 RegisterCollection 方法中会出现以下错误。我是不是设置有误？

The container can't be changed after the first call to GetInstance, GetAllInstances, Verify, and some calls of GetRegistration. Please see https://simpleinjector.org/locked to understand why the container is locked. The following stack trace describes the location where the container was locked:

记录器注册

 public static void Register(Container container)
 {
     container.RegisterConditional(typeof(ILogger), 
        c => typeof(NLogLogger<>).MakeGenericType(
            c.Consumer?.ImplementationType ?? typeof(object)),
        Lifestyle.Transient, 
        c => true);

...

}

container.RegisterCollection 抛出错误

container.Register<IEmailTemplatesService>(() => new EmailTemplatesService(emailTemplates,
    container.GetInstance<IEventEmailTemplatesRepository>(),
    container.GetInstance<IEmailTemplatesRepository>(),
    container.GetInstance<IEventSettingsRepository>(),
    container.GetInstance<IEmailsService>(),
    container.GetInstance<IUnitOfWork>(),
    container.GetInstance<IValidationProvider>()));

container.RegisterCollection<IStreamingMethod>(new List<IStreamingMethod>
{
    new CubeProvider(container.GetInstance<ILogger>()),
    new BallerTvProvider(container.GetInstance<ILogger>())
});

您收到此错误是因为您在容器设置期间调用了 GetInstance。正如例外情况和参考文档所解释的那样，这是不允许的。

问题是由于您尝试部分手动连接您的注册，而您应该更愿意让 Simple Injector 为您完成繁重的工作并自动连接所有内容。因此，您应该将注册更改为以下内容：

container.Register<IEmailTemplatesService, EmailTemplatesService>();

container.RegisterCollection<IStreamingMethod>(new[]
{
    typeof(CubeProvider),
    typeof(BallerTvProvider)
});
