How can I get my webapp's base URL in ASP.NET MVC?

I need to retrieve the base URL of my web app in an ASP.NET MVC project. Can someone explain the best way to get it dynamically within the application?

To get the base URL in an ASP.NET MVC application, you can use the following approach:

Using Request.Url in the Controller:

var baseUrl = Request.Url.GetLeftPart(UriPartial.Authority);

This retrieves the scheme (HTTP/HTTPS), hostname, and port from the request URL.

Using Url.Content for Relative Paths: Combine the base URL with a relative path using:

var fullUrl = baseUrl + Url.Content("~");
