| AddressAlreadyInUse | A value indicating that only one use of an address is normally permitted. | |
| AddressFamilyNotSupported | A value indicating that the specified address is incompatible with the requested protocol. | |
| AddressNotAvailable | A value indicating that the specified address is valid in this context. | |
| AlreadyInProgress | A value indicating that the nonblocking socket already has an operation in progress. | |
| ConnectionAborted | A value indicating that the connection was aborted by the .NET Micro Framework or the underlying socket provider. | |
| ConnectionRefused | A value indicating that the remote host is actively refusing a connection | |
| ConnectionReset | A value indicating that the connection was reset by the remote peer. | |
| DestinationAddressRequired | A value indicating that a required address was omitted from an operation on a socket. | |
| Disconnecting | A value indicating that a graceful shutdown is in progress. | |
| Fault | A value indicating that an invalid pointer address was detected by the underlying socket provider. | |
| HostDown | A value indicating that the operation failed because the remote host is down. | |
| HostNotFound | A value indicating that no such host is known. The name is not an official host name or alias. | |
| HostUnreachable | A value indicating that there is no network route to the specified host. | |
| InProgress | A value indicating that a blocking operation is in progress. | |
| Interrupted | A value indicating that a blocking Socket call was canceled. | |
| InvalidArgument | A value indicating that an invalid argument was supplied to a Socket member. | |
| IsConnected | A value indicating that the socket is already connected. | |
| MessageSize | A value indicating that the datagram is too long. | |
| NetworkDown | A value indicating that the network is not available | |
| NetworkReset | A value indicating that the application tried to set the KeepAlive configuration option on a connection that has already timed out. | |
| NetworkUnreachable | A value indicating that no route to the remote host exists. | |
| NoBufferSpaceAvailable | A value indicating that no free buffer space is available for a socket operation. | |
| NoData | A value indicating that the requested name or IP address was not found on the name server. | |
| NoRecovery | A value indicating that either the error is unrecoverable or the requested database cannot be located. | |
| NotConnected | A value indicating that the application tried to send or receive data, and the socket is not connected | |
| NotInitialized | A value indicating that the underlying socket provider has not been initialized. | |
| NotSocket | A value indicating that a socket operation was attempted on something that is not a socket. | |
| OperationNotSupported | A value indicating that the address family is not supported by the protocol family. | |
| ProcessLimit | A value indicating that too many processes are currently using the underlying socket provider. | |
| ProtocolFamilyNotSupported | A value indicating that the protocol family is not implemented or has not been configured. | |
| ProtocolNotSupported | A value indicating that the protocol is not implemented or has not been configured. | |
| ProtocolOption | A value indicating that an unknown, invalid, or unsupported configuration option or protocol was used with a socket. | |
| ProtocolType | A value indicating that the protocol type is incorrect for the socket. | |
| Shutdown | A value indicating that a request to send or receive data was disallowed because the socket has already been closed. | |
| SocketError | A value indicating that an unspecified socket error has occurred. | |
| SocketNotSupported | A value indicating that the support for the specified socket type does not exist in this address family. | |
| Success | A value indicating that the Socket operation succeeded. | |
| SystemNotReady | A value indicating that the network subsystem is unavailable. | |
| TimedOut | A value indicating that either the connection attempt timed out or the connected host has failed to respond. | |
| TooManyOpenSockets | A value indicating that there are too many open sockets in the underlying socket provider. | |
| TryAgain | A value indicating that the name of the host could not be resolved. Try again later. | |
| TypeNotFound | A value indicating that the specified type was not found. | |
| VersionNotSupported | A value indicating that the version of the underlying socket provider is out of range. | |
| WouldBlock | A value indicating that an operation on a nonblocking socket cannot be completed immediately. |
