asp.net core 如何自己调用路由系统，路由到controller

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Routing;

[ApiController]
public class MyController : ControllerBase {
    private readonly IInlineConstraintResolver _inlineConstraintResolver;
    private readonly IRouter _router;

    public MyController(IInlineConstraintResolver inlineConstraintResolver, IRouter router) {
        _inlineConstraintResolver = inlineConstraintResolver;
        _router = router;
    }

    public async Task<IActionResult> InvokeController(string controllerName, string actionName) {
        var values = new RouteValueDictionary(new { controller = controllerName, action = actionName });
        
        // 这里使用的是 ControllerContext，也可以通过创建自己的 ActionContext 实例来实现 
        var context = new ControllerContext();
        context.RouteData = new RouteData();
        context.RouteData.Values.Add("controller", controllerName);
        context.RouteData.Values.Add("action", actionName);

        var virtualPath = _router.GetVirtualPath(context, values); // 获取十分路径

        if (virtualPath == null) {
            return NotFound();
        }

        var routeContext = new RouteContext(context);
        routeContext.RouteData.Routers.Add(_router);
        routeContext.RouteData.Values = values;
        routeContext.HttpContext = HttpContext; // 指定当前请求的HttpContext
        routeContext.ConstraintResolver = _inlineConstraintResolver;

        await _router.RouteAsync(routeContext); // 执行路由匹配操作

        if (!routeContext.IsHandled) {
            return NotFound();
        }

        return new EmptyResult();
    }
}
