C# Web Development Project Tutorial: Building a Restaurant Review Website210

Introduction

In this tutorial, we will guide you through the process of building a complete restaurant review website using C#. We will cover the following aspects:* Setting up the project environment
* Creating models for data storage
* Establishing data access with Entity Framework
* Implementing controllers for handling actions
* Designing views for user interaction
* Deploying the website to a hosting platform

Prerequisites* Visual Studio 2022 or later
* .NET SDK 6.0 or later
* Basic understanding of C# and web development

1. Project Setup

Open Visual Studio and create a new Core Web Application project. Select the "Empty" template and name the project "RestaurantReviews".

2. Data Modeling

Let's define the data models that will represent our restaurant reviews. Create the following classes in the "Models" folder:```csharp
public class Restaurant
{
public int RestaurantId { get; set; }
public string Name { get; set; }
public string Address { get; set; }
public string PhoneNumber { get; set; }
public List? Reviews { get; set; }
}
public class Review
{
public int ReviewId { get; set; }
public int RestaurantId { get; set; }
public string Text { get; set; }
public int Rating { get; set; }
public Restaurant Restaurant { get; set; }
}
```

3. Data Access with Entity Framework

To establish data access, install the following NuGet packages:```powershell
Install-Package
Install-Package
```

Add the following code to the "" file to configure Entity Framework:```csharp
public void ConfigureServices(IServiceCollection services)
{
(options =>
{
("Server=(localdb)\\MSSQLLocalDB;Database=RestaurantReviews;Trusted_Connection=True;");
});
}
```

4. Controllers for Actions

Controllers handle incoming requests and perform actions. Create the following controllers in the "Controllers" folder:```csharp
public class HomeController : Controller
{
private readonly RestaurantDbContext _context;
public HomeController(RestaurantDbContext context)
{
_context = context;
}
public IActionResult Index()
{
var restaurants = ();
return View(restaurants);
}
}
public class RestaurantController : Controller
{
private readonly RestaurantDbContext _context;
public RestaurantController(RestaurantDbContext context)
{
_context = context;
}
public IActionResult Details(int id)
{
var restaurant =
.Include(r => )
.FirstOrDefault(r => == id);
return View(restaurant);
}
[HttpPost]
public IActionResult Create(Restaurant restaurant)
{
(restaurant);
();
return RedirectToAction("Index");
}
}
public class ReviewController : Controller
{
private readonly RestaurantDbContext _context;
public ReviewController(RestaurantDbContext context)
{
_context = context;
}
[HttpPost]
public IActionResult Create(int restaurantId, Review review)
{
var restaurant = (restaurantId);
(review);
();
return RedirectToAction("Details", "Restaurant", new { id = restaurantId });
}
}
```

5. Views for User Interaction

Views display data and collect user input. Create the following views in the "Views" folder:* "Home/" (list of restaurants)
* "Restaurant/" (details of a restaurant with reviews)
* "Restaurant/" (form for creating a restaurant)
* "Review/" (form for creating a review)

6. Configure Routing

In the "" file, configure routing to match URL patterns to controller actions:```csharp
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (())
{
();
}
();
(endpoints =>
{
(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
});
}
```

7. Deploy to Hosting Platform

Once the website is developed and tested, you can deploy it to a hosting platform. Here are some popular options:* Azure App Service
* Google Cloud Run
* AWS Elastic Beanstalk

Follow the instructions provided by your chosen platform to complete the deployment.

Conclusion

In this tutorial, we have guided you through the process of building a complete restaurant review website using C#. We have covered the essential aspects of data modeling, data access, controller actions, views, and deployment. By following this tutorial, you can now create your own web applications in C#.
