ASPNET核心 - 我可以在IApplicationModelConvention中添加一个ControllerModel吗？

Question

我试图动态添加控制器，但问题是他们的动作也是动态的，所以我不能简单地使用通用控制器。

我通过msdn挖掘，发现覆盖方法Apply@IApplicationModelConvention似乎是我最好的选择。但是，路由系统从未找到我添加的控制器。

这就是我的尝试：

 public void ConfigureServices(IServiceCollection services)
        {


            services.AddMvc(opts =>
            {
                opts.Conventions.Add(new ApplicationDescription("mdesc"));
                opts.Conventions.Add(new ControllerDescription("mctrl"));
            })
...
        }


public class ApplicationDescription : IApplicationModelConvention
    {
        private readonly string _description;

        public ApplicationDescription(string description)
        {
            _description = description;
        }

        public void Apply(ApplicationModel application)
        {
            var basec = application.Controllers[0];
            var cm = new ControllerModel(typeof(MyController).GetTypeInfo(), basec.Attributes);
            application.Controllers.Add(cm);
            application.Properties["description"] = _description;
        }
    }
