https://docs.microsoft.com/en-us/dotnet/api/system.uri?view=net-6.0
code snippet Uri uri = new Uri("https://user:password@www.contoso.com:80/Home/Index.htm?q1=v1&q2=v2#FragmentName");
using https with 80 port. I think this example url is not suitable and invalid. By the way, is there a function about validating url https with 443, http with 80?
Thanks
