Add a method DrawRatings in the controller HomeController. Open the file Controllers/HomeController.cs and add the following code:
The above code takes the number rating, makes some calculations to find the number of full stars, the number of empty stars and the number of half-full stars, after which it generates an HTML code, which orders a few pictures of stars one after the other so that it can make the rating picture from them. The ready HTML code is written down in ViewBag.Stars to visualize the view Index.cshtml.

In order to orientate yourself better, you can help yourself with the picture of Visual Studio below:
