Property Value

An Int32 value that contains 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 = new Uri("http://www.contoso.com/");
 Uri myUri = new 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);
