This constructor creates a Uri instance by combining the baseUri and the relativeUri. If relativeUri is an absolute URI (containing a scheme, host name, and optionally a port number), the Uri instance is created using only relativeUri.

This constructor does not ensure that the Uri refers to an accessible resource.

The following example creates a new instance of the Uri class by combining the relative URIs http://www.contoso.com and catalog/showew.htm to form the absolute URI http://www.contoso.com/catalog/shownew.htm.

Uri baseUri = new Uri("http://www.contoso.com");
 Uri myUri = new Uri(baseUri, "catalog/shownew.htm");

Console.WriteLine(myUri.ToString());
   

Uri baseUri = new Uri("http://www.contoso.com");
Uri myUri = new Uri(baseUri, "catalog/shownew.htm");
Console.WriteLine(myUri.ToString());

var baseUri : Uri = new Uri("http://www.contoso.com");
var myUri : Uri = new Uri(baseUri, "catalog/shownew.htm");
Console.WriteLine(myUri.ToString());
