Why should you care?

Admin panels and reports need file features beyond simple CRUD.

See it live — copy this example

Create an MVC project (dotnet new mvc), add the code, and run dotnet run.

// File Handling — ShopNest.Mvc example
public class HomeController : Controller
{
    public IActionResult Index() => View();
}

Run Example »

Edit the code and click Run — like W3Schools Try it Yourself.

What happened?

• Study the example line by line.
• Each part connects to File Handling in MVC.
• Edit one line, save, and run dotnet run to see what changes.

Try it yourself

1. Run the upload or export once locally.
2. Verify file type and size rules if the lesson includes them.
3. Store files outside wwwroot when the lesson says so.
4. Change text or labels in the example and run again — watch the browser update.
5. Break the code on purpose (remove a semicolon), read the error message, then fix it.

Remember

You learned what File Handling in MVC is and when to use it. Practice by changing the example yourself. Explain it in your own words before moving on.
