What are some examples of model binding in ASP.NET?

Model binding in ASP.NET is a process that maps data from HTTP requests to action method parameters. For example, if you have a form that submits user data, model binding can automatically create an object from that data.

Can you give me a specific code example?

Sure! Here's a simple example:

public class User
{
    public string Name { get; set; }
    public int Age { get; set; }
}

[HttpPost]
public IActionResult Create(User user)
{
    // user.Name and user.Age are populated from the form data
    return View();
}

What types of data can be bound?

Model binding can handle various data types, including primitive types (like int, string), complex types (like classes), and collections (like lists). It can also bind data from query strings, form data, and route data.

Are there any limitations to model binding?

Yes, some limitations include the need for public setters on properties, and it may not bind complex types if they don't have a parameterless constructor.
