Namespace: System
Assembly: System (in system.dll)

public:
property int Port {
	int get ();
}
/** @property */
public int get_Port ()

public function get Port () : int

Property Value

An Int32 value containing the port number for this URI.

Exception typeCondition

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 = gcnew Uri( "http://www.contoso.com/" );
Uri^ myUri = gcnew Uri( baseUri,"catalog/shownew.htm?date=today" );
Console::WriteLine( myUri->Port );

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

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