What is the difference between model binding and parameter binding in ASP.NET?

Model binding in ASP.NET automatically maps data from HTTP requests to action method parameters, while parameter binding requires you to specify each parameter explicitly.

Can you give me an example of model binding?

Sure! If you have a form with fields for 'Name' and 'Age', model binding can automatically create an object of a class with those properties from the form data.

And how does parameter binding work?

With parameter binding, you would define each parameter in your action method, like 'public IActionResult MyAction(string name, int age)', and ASP.NET will match the request data to those parameters.

Which one is better to use?

It depends on your needs. Model binding is more convenient for complex objects, while parameter binding gives you more control over individual parameters.
