How do I implement model binding in ASP.NET?

Model binding in ASP.NET allows you to map data from HTTP requests to action method parameters. You can implement it by defining your model class and using it as a parameter in your controller action.

Can you give me an example of a model class?

Sure! Here's a simple example:

public class Product {
    public int Id { get; set; }
    public string Name { get; set; }
    public decimal Price { get; set; }
}

How do I use this model in a controller action?

You can use the model as a parameter in your action method like this:

public IActionResult Create(Product product) {
    if (ModelState.IsValid) {
        // Save the product to the database
    }
    return View(product);
}

What if the model validation fails?

If the model validation fails, the ModelState.IsValid will return false, and you can return the same view with the model to display validation errors.
