Property Value

Socket control data on a DatagramSocket object.

Windows requirements

App capabilities


The Control property gets the DatagramSocketControl instance associated with a DatagramSocket object. A DatagramSocketControl object is automatically created with the parent DatagramSocket object. The DatagramSocketControl instance can then be used to get or set control data used by the DatagramSocket. These properties on the DatagramSocketControl instance include the following:

The OutboundUnicastHopLimit property can be set before or after the DatagramSocket is bound or connected. Before changing this value on a bound or connected DatagramSocket, any outgoing packets should first be flushed to ensure that all previously-written data is sent out with the previous hop limit.

Any changes to the other property values on the DatagramSocketControl must be set before the DatagramSocket is bound or connected. As a result if you need to make changes to the DontFragment, InboundBufferSizeInBytes, or QualityOfService properties, then these changes must occur before a successful call to the BindEndpointAsync, BindServiceNameAsync, or one of the ConnectAsync methods on the DatagramSocket.
