如何为ASP.NET Core3.x项目设置MyControllerFactory

using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Controllers;
using System;

public class MyControllerFactory : DefaultControllerFactory
{
    public override object CreateController(ControllerContext context)
    {
        // 在这里可以进行自定义的控制器实例化逻辑
        // 返回一个控制器实例
        return base.CreateController(context);
    }

    public override void ReleaseController(ControllerContext context, object controller)
    {
        // 在这里可以进行自定义的控制器释放逻辑
        base.ReleaseController(context, controller);
    }
}

using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.DependencyInjection;

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        services.AddControllersWithViews();

        // 注册自定义的Controller工厂类
        services.AddSingleton<IControllerFactory, MyControllerFactory>();
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 配置其他中间件和路由等
        app.UseRouting();

        app.UseEndpoints(endpoints =>
        {
            endpoints.MapControllerRoute(
                name: "default",
                pattern: "{controller=Home}/{action=Index}/{id?}");
        });
    }
}

public override object CreateController(ControllerContext context)
{
    var controllerName = context.RouteData.Values["controller"].ToString();

    // 根据控制器名称动态创建控制器实例
    if (controllerName == "MyController1")
    {
        return new MyController1();
    }
    else if (controllerName == "MyController2")
    {
        return new MyController2();
    }

    // 默认情况下，调用基类的实现
    return base.CreateController(context);
}
