Fields

Name	Value	Description
SocketError	-1	An unspecified Socket error has occurred.
Success	0	The Socket operation succeeded.
OperationAborted	995	The overlapped operation was aborted due to the closure of the Socket.
IOPending	997	The application has initiated an overlapped operation that cannot be completed immediately.
Interrupted	10004	A blocking Socket call was canceled.
AccessDenied	10013	An attempt was made to access a Socket in a way that is forbidden by its access permissions.
Fault	10014	An invalid pointer address was detected by the underlying socket provider.
InvalidArgument	10022	An invalid argument was supplied to a Socket member.
TooManyOpenSockets	10024	There are too many open sockets in the underlying socket provider.
WouldBlock	10035	An operation on a nonblocking socket cannot be completed immediately.
InProgress	10036	A blocking operation is in progress.
AlreadyInProgress	10037	The nonblocking Socket already has an operation in progress.
NotSocket	10038	A Socket operation was attempted on a non-socket.
DestinationAddressRequired	10039	A required address was omitted from an operation on a Socket.
MessageSize	10040	The datagram is too long.
ProtocolType	10041	The protocol type is incorrect for this Socket.
ProtocolOption	10042	An unknown, invalid, or unsupported option or level was used with a Socket.
ProtocolNotSupported	10043	The protocol is not implemented or has not been configured.
SocketNotSupported	10044	The support for the specified socket type does not exist in this address family.
OperationNotSupported	10045	The address family is not supported by the protocol family.
ProtocolFamilyNotSupported	10046	The protocol family is not implemented or has not been configured.
AddressFamilyNotSupported	10047	The address family specified is not supported. This error is returned if the IPv6 address family was specified and the IPv6 stack is not installed on the local machine. This error is returned if the IPv4 address family was specified and the IPv4 stack is not installed on the local machine.
AddressAlreadyInUse	10048	Only one use of an address is normally permitted.
AddressNotAvailable	10049	The selected IP address is not valid in this context.
NetworkDown	10050	The network is not available.
NetworkUnreachable	10051	No route to the remote host exists.
NetworkReset	10052	The application tried to set KeepAlive on a connection that has already timed out.
ConnectionAborted	10053	The connection was aborted by .NET or the underlying socket provider.
ConnectionReset	10054	The connection was reset by the remote peer.
NoBufferSpaceAvailable	10055	No free buffer space is available for a Socket operation.
IsConnected	10056	The Socket is already connected.
NotConnected	10057	The application tried to send or receive data, and the Socket is not connected.
Shutdown	10058	A request to send or receive data was disallowed because the Socket has already been closed.
TimedOut	10060	The connection attempt timed out, or the connected host has failed to respond.
ConnectionRefused	10061	The remote host is actively refusing a connection.
HostDown	10064	The operation failed because the remote host is down.
HostUnreachable	10065	There is no network route to the specified host.
ProcessLimit	10067	Too many processes are using the underlying socket provider.
SystemNotReady	10091	The network subsystem is unavailable.
VersionNotSupported	10092	The version of the underlying socket provider is out of range.
NotInitialized	10093	The underlying socket provider has not been initialized.
Disconnecting	10101	A graceful shutdown is in progress.
TypeNotFound	10109	The specified class was not found.
HostNotFound	11001	No such host is known. The name is not an official host name or alias.
TryAgain	11002	The name of the host could not be resolved. Try again later.
NoRecovery	11003	The error is unrecoverable or the requested database cannot be located.
NoData	11004	The requested name or IP address was not found on the name server.

Remarks

Most of these errors are returned by the underlying socket provider.
