SocketFlags Enumeration
.NET Framework 2.0
Specifies socket send and receive behaviors.
Assembly: System (in system.dll)
This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.
Namespace: System.Net.SocketsAssembly: System (in system.dll)
| Member name | Description | |
|---|---|---|
| Broadcast | Indicates a broadcast packet. | |
| ControlDataTruncated | Indicates that the control data did not fit into an internal 64-KB buffer and was truncated. | |
|
DontRoute | Send without using routing tables. |
|
|
MaxIOVectorLength | Provides a standard value for the number of WSABUF structures that are used to send and receive data. |
| Multicast | ||
|
|
None | Use no flags for this call. |
|
|
OutOfBand | Process out-of-band data. |
|
|
Partial | Partial send or receive for message. |
|
|
Peek | Peek at the incoming message. |
| Truncated | The message was too large to fit into the specified buffer and was truncated. |
The following example sends data and specifies None for SocketFlags.
// Displays sending with a connected socket // using the overload that takes a buffer, message size, and socket flags. public static int SendReceiveTest3(Socket server) { byte[] msg = Encoding.UTF8.GetBytes("This is a test"); byte[] bytes = new byte[256]; try { // Blocks until send returns. int i = server.Send(msg, msg.Length, SocketFlags.None); Console.WriteLine("Sent {0} bytes.", i); // Get reply from the server. int byteCount = server.Receive(bytes, server.Available, SocketFlags.None); if (byteCount > 0) Console.WriteLine(Encoding.UTF8.GetString(bytes)); } catch (SocketException e) { Console.WriteLine("{0} Error code: {1}.", e.Message, e.ErrorCode); return (e.ErrorCode); } return 0; }
// Displays sending with a connected socket
// using the overload that takes a buffer, message size, and socket flags.
public static int SendReceiveTest3(Socket server)
{
ubyte msg[] = Encoding.get_UTF8().GetBytes("This is a test");
ubyte bytes[] = new ubyte[256];
try {
// Blocks until send returns.
int i = server.Send(msg, msg.get_Length(), SocketFlags.None);
Console.WriteLine("Sent {0} bytes.", (Int32)i);
// Get reply from the server.
server.Receive(bytes, server.get_Available(), SocketFlags.None);
Console.WriteLine(Encoding.get_UTF8().GetString(bytes));
}
catch (SocketException e) {
Console.WriteLine("{0} Error code: {1}.", e.get_Message(),
(Int32)e.get_ErrorCode());
return e.get_ErrorCode();
}
return 0;
} //SendReceiveTest3
