Try this:

In the controller:

string myHostUrl = $"{HttpContext.Request.Scheme}://{HttpContext.Request.Host}";

Outside the controller:

public class YourClass 
{
   private readonly IHttpContextAccessor _httpContextAccessor;
   public YourClass(IHttpContextAccessor httpContextAccessor)
   {
      _httpContextAccessor = httpContextAccessor;
   }

   public void YourMethod()
   {
      string myHostUrl = $"{_httpContextAccessor.HttpContext.Request.Scheme}://{_httpContextAccessor.HttpContext.Request.Host}";
   }
}

And then register IHttpContextAccessor in the Startup class as follows:

public void ConfigureServices(IServiceCollection services)
{
    services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

    // Or you can also register as follows

    services.AddHttpContextAccessor();
}
