ASP。NET MVC表单验证每次都失败

Upon successful validation of the form, I'm unable to redirect the form. Please help me. I'm very new to ASP.NET and MVC Concepts. I have given below the model, the view and the controller. The Index page displays login information, and I'm submitting the form to the same page. If there are no errors, I have to redirect the form to a different page. This is what I'm trying to do. But even If I provide valid login information, the form doesn't redirect to the specified page.

成功验证表单后，我无法重定向表单。请帮助我。我对ASP很陌生。净和MVC概念。我在下面给出了模型，视图和控制器。索引页显示登录信息，我将表单提交到相同的页面。如果没有错误，我必须将表单重定向到另一个页面。这就是我要做的。但是即使我提供了有效的登录信息，表单也不会重定向到指定的页面。

You have to actually return the result of the RedirectToAction call. Change RedirectToAction to be return RedirectToAction in your controller HttpPost method:

实际上，您必须返回RedirectToAction调用的结果。在您的控制器HttpPost方法中，将RedirectToAction更改为return RedirectToAction:

[HttpPost]
public ActionResult Index(LoginModel model)
{
    if (ModelState.IsValid)
    {
        return RedirectToAction("Transfer", "Home");
    }

    return View(model);
}
