How to save uploaded pictures using ASP.NET Core 5.0?

Question

ASP.NET

Hello, I am doing the final project, the theme of the project is the site of crowdfunding companies. And on the page for creating a company there is a field for adding pictures. Pictures must be uploaded using Drag and Drop. When creating the code, I relied on this site - https://habr.com/en/post/125424/ . I did everything except for this: "The server part. All that remains for us is to write a simple handler that will save the file in the location we need. I will not go into writing a handler much, but just give a small example in PHP."

<?php
$uploaddir = getcwd().DIRECTORY_SEPARATOR.'upload'.DIRECTORY_SEPARATOR;
$uploadfile = $uploaddir.basename($_FILES['file']['name']);
move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile);
?>

Please tell me how to save pictures using ASP.NET Core 5.0. I can't use PHP language since I don't use it in my project.

Here is the code for the company creation page:

@page
@model MyWebSIte.Pages.Company.CreateModel

@{
    ViewData["Title"] = "Create";
}

@using Microsoft.AspNetCore.Mvc.Localization
@inject IViewLocalizer Localizer

<link rel="stylesheet" href="/css/create.css">
