The is already connected.

The datagram is too long.

The network is not available.

The application tried to set on a connection that has already timed out.

No route to the remote host exists.

No free buffer space is available for a operation.

The requested name or IP address was not found on the name server.

The error is unrecoverable or the requested database cannot be located.

The application tried to send or receive data, and the is not connected.

The underlying socket provider has not been initialized.

A operation was attempted on a non-socket.

The overlapped operation was aborted due to the closure of the .

The address family is not supported by the protocol family.

Too many processes are using the underlying socket provider.

The protocol family is not implemented or has not been configured.

The protocol is not implemented or has not been configured.

An unknown, invalid, or unsupported option or level was used with a .

The protocol type is incorrect for this .

A request to send or receive data was disallowed because the has already been closed.

An unspecified error has occurred.

The support for the specified socket type does not exist in this address family.

The operation succeeded.

The network subsystem is unavailable.

The connection attempt timed out, or the connected host has failed to respond.

There are too many open sockets in the underlying socket provider.

The name of the host could not be resolved. Try again later.

The specified class was not found.

The version of the underlying socket provider is out of range.

An operation on a nonblocking socket cannot be completed immediately.

The exception that is thrown when a socket error occurs.

Initializes a new instance of the class with the last operating system error code.

Initializes a new instance of the class with the specified error code.

The error code that indicates the error that occurred.

Gets the error message that is associated with this exception.

A string that contains the error message.

Gets the error code that is associated with this exception.

An integer error code that is associated with this exception.
