Can't change pages .NET

Question

I'm trying to switch views from a controller after checking the login info. How can I properly switch to the correct view after running this logic?

I want to switch to the question explanation view. My existing code is below:

[HttpPost]
public IActionResult LoginBody(LoginModel info)
{
    System.Diagnostics.Debug.WriteLine(info.Email);
    System.Diagnostics.Debug.WriteLine(info.Password);

    //Some login Verification Logic

   return View("~\\Views\\QuestionExplanation\\QuestionExplanation");        
}

My folders are organized as follows:

The code for the QuestionExplanationController is as follows:

namespace OliviaSite.Controllers
{
    public class QuestionExplanationController : Controller
    {
        // GET: /<controller>/
        [HttpGet]
        public IActionResult ShowView()
        {
            return View();
        }
    }
}

`return RedirectToAction("QuestionExplaination","QuestionExplaination");` Where the first argument stands for the Action and the second for the Controller. If you want to pass an argument see [here](https://stackoverflow.com/a/1257632/4625144). — Dimitar Nikovski, Jan 07 '18 at 19:16
@DimitarNikovski I get a blank page and when I inspect, I get a 404 error from that. Do you know why that might happen? — DMop, Jan 07 '18 at 19:24
What methods are in your QuestionExplanation controller, and does it exist at all? — Adam Brown, Jan 07 '18 at 19:43
@AdamBrown It exists in my controllers folder along with LoginController (where this logic is happening) The only method I have is "ShowView" which just returns the view — DMop, Jan 07 '18 at 19:52

As Dimitar Nikovski said, you can return RedirectToAction from login action to redirect into ShowView action method:

[HttpPost]
public IActionResult LoginBody(LoginModel info)
{
    System.Diagnostics.Debug.WriteLine(info.Email);
    System.Diagnostics.Debug.WriteLine(info.Password);

    //Some login Verification Logic

   // usage: RedirectToAction("action_name", "controller_name")
   return RedirectToAction("ShowView", "QuestionExplanation");        
}

Then, mention target view name in ShowView action method (you can use any different view name other than action name, ensure that view name exists in Views/QuestionExplanation):

// QuestionExplanationController
[HttpGet]
public IActionResult ShowView()
{
    return View("QuestionExplanation"); // mention view name here
}

The 404 error occurred because view engine tried to find view name supplied by LoginBody method which was incorrectly set.

NB: This path seems incorrect:

return View("~\\Views\\QuestionExplanation\\QuestionExplanation");

The correct relative path should be like this, based on similar issue:

return View("~/Views/QuestionExplanation/QuestionExplanation.cshtml");
