DatagramSocketInformation.LocalPort | localPort property

The local service name or UDP port number associated with a DatagramSocket.

Syntax


var localPort = datagramSocketInformation.localPort;

Property value

Type: String [JavaScript] | System.String [.NET] | Platform::String [C++]

The local service name or UDP port number.

Remarks

The LocalPort property represents the local service name or UDP port number bound to the DatagramSocket object.

An app can set the local service name or UDP port number to use by calling the BindEndpointAsync , BindServiceNameAsync, ConnectAsync(EndpointPair) , or GetOutputStreamAsync(EndpointPair) methods on the DatagramSocket. The bind or connect operation will bind the socket to the specific local IP address and local UDP port number. After the bind or connect operation completes, LocalAddress property contains the IP address and the LocalPort property contains the local UDP port number that the local hostname and service name resolved to.

If the local service name or UDP port number passed to the BindEndpointAsync , BindServiceNameAsync, ConnectAsync(EndpointPair) , or GetOutputStreamAsync(EndpointPair) methods is an empty string or the ConnectAsync(HostName, String) or GetOutputStreamAsync(HostName, String) method is called, the system will determine the local UDP port to bind to the DatagramSocket object.
