This instance represents a relative URI, and this property is valid only for absolute URIs.

The following example creates a Uri instance and checks whether it uses the default port.

// Create Uri
Uri uriAddress = new Uri("http://www.contoso.com/index.htm#search");
Console.WriteLine(uriAddress.Fragment);
Console.WriteLine("Uri {0} the default port ", uriAddress.IsDefaultPort ? "uses" : "does not use");

Console.WriteLine("The path of this Uri is {0}", uriAddress.GetLeftPart(UriPartial.Path));
Console.WriteLine("Hash code {0}", uriAddress.GetHashCode());
// Create Uri
Uri* uriAddress = new Uri(S"http://www.contoso.com/index.htm#search");
Console::WriteLine(uriAddress->Fragment);
Console::WriteLine(S"Uri {0} the default port ", uriAddress->IsDefaultPort ? S"uses" : S"does not use");

Console::WriteLine(S"The path of this Uri is {0}", uriAddress->GetLeftPart(UriPartial::Path));
Console::WriteLine(S"Hash code {0}", __box(uriAddress->GetHashCode()));
