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.
