C# 使用简单注入器的MVC中没有带模型绑定的无参数构造函数

我有一个Asp.NETMVC4应用程序，我使用的是简单的注入器，我配置了应用程序启动时的所有内容，但当我尝试发布一个示例表单（当系统需要注入器时）时，该对象显示“未定义构造函数参数”。这意味着注入不起作用，但我认为所有配置都很好

SimpleInjector初始值设定项类：

[assembly: WebActivator.PostApplicationStartMethod(typeof(SimpleInjectorInitializer), "Initialize")]
    public static class SimpleInjectorInitializer
    {
        public static void Initialize()
        {
            var container = new Container();
            container.Options.DefaultScopedLifestyle = new WebRequestLifestyle();

            InitializeContainer(container);
            container.RegisterMvcControllers(Assembly.GetExecutingAssembly());
            container.Verify();

            DependencyResolver.SetResolver(new SimpleInjectorDependencyResolver(container));
        }

    private static void InitializeContainer(Container container)
    {
        SimpleInjectorContainer.RegisterContainer(container);
    }
}

容器类（其中注册我的依赖项）

公共静态类SimpleInjector容器
{
公共静态无效注册表容器（容器）
{
container.registerWebRequest（）；
}
}

我已经有了以下程序集：

简单喷射器 SimpleInjector.Integration.Web SimpleInjector.Integration.Web.Mvc

您正试图将依赖项注入到视图模型对象中。MVC默认不支持这一点，Simple Injector集成包也不支持这一点，因为将运行时数据与依赖项混合是一个坏主意

---

视图模型不应包含任何行为。一旦您分离了数据和行为，就不需要将依赖项注入到视图模型中，您的问题就会出现
