How to manually check if model is valid or not

Question

Sure, here are the steps on how to manually check if a model is valid or not in MVC:
Get the ModelState object from the controller action.Check the ModelState.IsValid property.If the ModelState.IsValid property is false, then the model is not valid.Otherwise, the model is valid.
Here is an example of how to manually check if a model is valid or not in MVC:
C#
public class IndexModel
{
  public string Name { get; set; }
}
public class IndexController : Controller
{
  public ActionResult Index()
  {
    // Get the model.
    var model = new IndexModel();
    // Check the model validity.
    if (!ModelState.IsValid)
    {
      // The model is not valid.
      return View(model);
    }
    // The model is valid.
    return RedirectToAction("Success");
  }
}
This code will create a controller action that checks the validity of the IndexModel model. If the model is not valid, then the action will render the Index view. Otherwise, the action will redirect to the Success action.
The ModelState object is a dictionary that contains the validation errors for the model. The ModelState.IsValid property is a Boolean property that indicates whether the model is valid or not. If the ModelState.IsValid property is true, then the model is valid. Otherwise, the model is not valid.
