Use this value if you want to determine how long a closed System.Net.Sockets.Socket will attempt to transfer unsent data before timing out. You can also set this value to the desired time-out period, in seconds.

If the LingerOption.Enabled property is true, and you set LingerOption.LingerTime to 0, the System.Net.Sockets.Socket discards any pending data to send in the outgoing network buffer. If you change this value, you must pass the altered System.Net.Sockets.LingerOption instance to the Socket.SetSocketOption(SocketOptionLevel, SocketOptionName, int) method or set the TcpClient.LingerState or Socket.LingerState property.

The following table describes the behavior for the possible values of the LingerOption.Enabled property and the LingerOption.LingerTime property stored in the Socket.LingerState property.

false (disabled), the default value	The time-out is not applicable, (default).	Attempts to send pending data for a connection-oriented socket (TCP, for example) until the default IP protocol time-out expires.
true (enabled)	A nonzero time-out	Attempts to send pending data until the specified time-out expires, and if the attempt fails, then Winsock resets the connection.
true (enabled)	A zero timeout.	Discards any pending data. For connection-oriented socket (TCP, for example), Winsock resets the connection.

The IP stack computes the default IP protocol time-out period to use based on the round trip time of the connection. In most cases, the time-out computed by the stack is more relevant than one defined by an application. This is the default behavior for a socket when the Socket.LingerState property is not set.

When the LingerOption.LingerTime property stored in the Socket.LingerState property is set greater than the default IP protocol time-out, the default IP protocol time-out will still apply and override.
