如何在整个应用程序中仅使用一个MVC控制器？

Question

Is it possible Single Controller for Entire MVC Application to Route Views Or can we Rename Controller Name at Run-time to Route Views?.. 

我尝试了以下代码以使路由视图正常运行。 控制器：-

public class HomeController : Controller
{
 public ActionResult Commmon_Method(string VN, string Id)
 {
   return View(@"~/" + VN + ".cshtml");
 }
}

查看页面：

$('#btn_Test').click(function () {
        window.location.href = '@Url.Action("Commmon_Method", "Home")?Id=' + 1 + '&VN=' + 'Views/Test/Index2';
    });

输出网址：-

http://localhost:52296/Home/Commmon_Method?Id=1&VN=Views/Test2/Index

--------------------------------- * ----------------- ----

即使我像基于MVC的动态路由一样尝试了自己，但未能成功：

http://localhost:52296/Home/Test2/Index

因此，控制器名称应为单个以提供所有请求，我也尝试了运行时控制器，而基于自定义的控制器未成功

我在MVC中成功实现了单个动态JSON数据方法，因此无需再编写代码束即可使用Jquery Ajax方法获取JSON数据。

在MVC中，只有基于单控制器的路由成功，这意味着MVC将是非常简单的开发应用程序，因此，您可以分享您的知识来简化复杂的开发方式吗？

html：-

window.location.href = '@Url.Action("common_dll", "Home")?ctrl=Test';

用于创建Controller的Controller方法：

public ActionResult common_dll(string ctrl)
        {
            StringBuilder sb = new StringBuilder();

            sb.Append("using System;" + Environment.NewLine);
            sb.Append("using System.Collections.Generic;" + Environment.NewLine);
            sb.Append("using System.Data;" + Environment.NewLine);
            sb.Append("using System.Data.SqlClient;" + Environment.NewLine);
            sb.Append("using System.Dynamic;" + Environment.NewLine);
            sb.Append("using System.Linq;" + Environment.NewLine);
            sb.Append("using System.Text;" + Environment.NewLine);
            sb.Append("using System.Web.Mvc;" + Environment.NewLine);

            sb.Append("namespace Testing_MVC.Controllers" + Environment.NewLine);
            sb.Append("{" + Environment.NewLine);

            sb.Append("public class " + ctrl + "Controller" + " : Controller" + Environment.NewLine);
            sb.Append("{" + Environment.NewLine);

            sb.Append("public ActionResult Index()" + Environment.NewLine);
            sb.Append("{" + Environment.NewLine);
            sb.Append("return View();" + Environment.NewLine);
            sb.Append("}" + Environment.NewLine);

            sb.Append("}" + Environment.NewLine);

            sb.Append("}" + Environment.NewLine);

            var dir = Server.MapPath("~\\Controllers");
            var file = System.IO.Path.Combine(dir, ctrl + "Controller" + ".cs");
            System.IO.Directory.CreateDirectory(dir);
            System.IO.File.WriteAllText(file, sb.ToString());

            return this.RedirectToAction("Index", ctrl, new { id = 1 });
        }
