Can we use Nested switch case in C# or switch case under if else case in ASP.NET C#?

Hello, you can use nested switch case for better output or you can also use Nested-If, here is the general C# syntax of nested Switch

switch(ID1) {
   case 'A':
   Console.WriteLine("This A is part of outer switch" );
   
   switch(ID2) {
      case 'A':
         Console.WriteLine("This A is part of inner switch" );
         break;
      case 'B': /* inner B case code */
   }
   break;
   case 'B': /* outer B case code */
}

So, in your controller code you can have code something like this

public ActionResult Index()
        {
            int rating = 1;
            int DestinationId = 2;

            switch (rating)
            {
                case 1:
                    switch (DestinationId)
                    {
                        case 2:
                           //this will redirect to action Case2 directly and no other options will be executed
                            return RedirectToAction("Case2");

                    }
                    break;
                   
                    
                case 2:
                    switch (DestinationId)
                    {
                        case 3:
                            return RedirectToAction("Case3");

                    }
                    break;
                    
            }
                    return View();
        }
