public void SetSocketOption(System.Net.Sockets.SocketOptionLevel optionLevel, System.Net.Sockets.SocketOptionName optionName, bool optionValue);
member this.SetSocketOption : System.Net.Sockets.SocketOptionLevel * System.Net.Sockets.SocketOptionName * bool -> unit
Public Sub SetSocketOption (optionLevel As SocketOptionLevel, optionName As SocketOptionName, optionValue As Boolean)
Parameters
The value of the option, represented as a Boolean.
ExceptionsThe Socket object has been closed.
An error occurred when attempting to access the socket.
ExamplesThe following code example opens a socket and enables the DontLinger
and the OutOfBandInline
socket options.
// Establish the local endpoint for the socket.
IPHostEntry ipHost = Dns.GetHostEntry(Dns.GetHostName());
IPAddress ipAddr = ipHost.AddressList[0];
IPEndPoint ipEndPoint = new IPEndPoint(ipAddr, 11000);
// Create a TCP socket.
Socket client = new Socket(AddressFamily.InterNetwork,
SocketType.Stream, ProtocolType.Tcp);
// Connect the socket to the remote endpoint.
client.Connect(ipEndPoint);
// Set option that allows socket to close gracefully without lingering.
client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.DontLinger, true);
// Set option that allows socket to receive out-of-band information in the data stream.
client.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.OutOfBandInline, true);
Remarks
Socket options determine the behavior of the current Socket. Set optionValue
to true
to enable the option, or to false
to disable the option.
Socket options are grouped by level of protocol support.
Listed below are the various Socket options that can be set using this overload. These options are grouped by the appropriate SocketOptionLevel value. If you intend to set any of these options, be sure to use the appropriate SocketOptionLevel value for the optionLevel
parameter. The option you choose to set must be specified in the optionName
parameter. If you want to get the current value of any of the options listed, use the GetSocketOption method.
SocketOptionLevel.Socket options that can be set using this overload.
SocketOptionLevel.IP options that can be set using this overload.
SocketOptionLevel.Tcp options that can be set using this overload.
SocketOptionLevel.Udp options that can be set using this overload.
For more information on these options, refer to the SocketOptionName enumeration.
