Remarks
The port number defines the protocol port used for contacting the server referenced in the URI. If a port is not specified as part of the URI, the Port property returns the default value for the protocol. If there is no default port number, this property returns -1.
Examples
The following example writes the URI port number to the console. In this case, the value is the default port number for HTTP, port 80.
Dim baseUri As New Uri("https://www.contoso.com/")
Dim myUri As New Uri(baseUri, "catalog/shownew.htm?date=today")
outputBlock.Text &= "Uri.Port: "
outputBlock.Text &= myUri.Port
outputBlock.Text &= vbCrLf
Uri baseUri = new Uri("https://www.contoso.com/");
Uri myUri = new Uri(baseUri,"catalog/shownew.htm?date=today");
outputBlock.Text += "Uri.Port: ";
outputBlock.Text += myUri.Port;
outputBlock.Text += "\n";
