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