Namespace:  System

public int Port { get; }

Property Value

Type: System.Int32
An Int32 value that contains the port number for this URI.

ExceptionCondition
InvalidOperationException

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

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.

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.

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

 Console.WriteLine(myUri.Port);
