Extract domain names from a list of web site urls RRS feed

  • Question

  • I am working on an asp.net console application. and the console application reads the websites from an external service. but the websites comes with different formats,,, these are samples of the formats:-

    now i need to only extract the domain name from the above urls (i do not need to include http or https or wwww , etc..). so i am not sure which is the best appraoch to do so? i need this as i am using a .netlibrary named https://www.nuget.org/packages/ARSoft.Tools.Net which allow me to get the email hosting company from the website domain name.. but if i apply the above urls i will get errors except for the last url which only include the domain name which i am looking to extract...

    so can anyone advice on this please?

  • See if the following is helpful.


    From the link above

    string host = Request.Url.Host;


    Uri myUri = new Uri("http://www.contoso.com:8080/");   
    string host = myUri.Host;  // host is "www.contoso.com"
    Uri.GetLeftPart( UriPartial.Authority )

  • UrlGetPartW does this, but only for the 4 first ones in your sample (when there is http inside)
