Type: System.Int32

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

Exception Condition
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.

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

Console.WriteLine(myUri.Port)
