Открытые методы

Метод	Описание
Close ( ) : void	Close network socket
Dispose ( ) : void	Dispose of the class.
Request ( IPAddress peer, int port, byte buffer, int bufferLength, int timeout, int retries ) : byte[]	Make sync request using IP/UDP with request timeouts and retries.

Защищенные методы

Метод	Описание
initSocket ( bool useV6 ) : void	Initialize class socket

Приватные методы

Метод	Описание
AsyncRequestTimerCallback ( object stateInfo ) : void	Internal timer callback. Called by _asyncTimer when SNMP request timeout has expired
ReceiveBegin ( ) : void	Begin async version of ReceiveFrom member of the socket class.
ReceiveFromCallback ( IAsyncResult ar ) : void	Internal callback called as part of Socket.BeginReceiveFrom. Process incoming packets and notify caller of results.
RequestAsync ( IPAddress peer, int port, byte buffer, int bufferLength, int timeout, int retries, SnmpAsyncCallback asyncCallback ) : bool	Begin an async SNMP request
RetryAsyncRequest ( ) : void	Internal retry function. Checks if request has reached maximum number of retries and either resends the request if not reached, or sends request timed-out notification to the caller if maximum retry count has been reached and request has failed.
SendToBegin ( ) : void	Calls async version of the SendTo socket function.
SendToCallback ( IAsyncResult ar ) : void	Callback member called on completion of BeginSendTo send data operation.

Описание методов

Close() публичный Метод

Close network socket

public Close ( ) : void
Результат	void

Dispose() публичный Метод

Dispose of the class.

public Dispose ( ) : void
Результат	void

Request() публичный Метод

Make sync request using IP/UDP with request timeouts and retries.

Thrown on request timed out. SnmpException.ErrorCode is set to /// SnmpException.RequestTimedOut constant. Thrown when IPv4 address is passed to the v6 socket or vice versa

public Request ( IPAddress peer, int port, byte buffer, int bufferLength, int timeout, int retries ) : byte[]
peer	System.Net.IPAddress	SNMP agent IP address
port	int	SNMP agent port number
buffer	byte	Data to send to the agent
bufferLength	int	Data length in the buffer
timeout	int	Timeout in milliseconds
retries	int	Maximum number of retries. 0 = make a single request with no retry attempts
Результат	byte[]

UdpTransport() публичный Метод

Constructor. Initializes and binds the Socket class

public UdpTransport ( bool useV6 ) : System
useV6	bool	Set to true if you wish to initialize the transport for IPv6
Результат	System

initSocket() защищенный Метод

Initialize class socket

protected initSocket ( bool useV6 ) : void
useV6	bool	Should socket be initialized for IPv6 (true) of IPv4 (false)
Результат	void

Описание свойств

_isIPv6 защищенное свойство

Flag showing if class is using IPv6 or IPv4

protected bool _isIPv6
Результат	bool

_noSourceCheck защищенное свойство

Internal variable used to disable host IP address/port number check on received SNMP reply packets. If this option is disabled (default) only replies from the IP address/port number combination to which the request was sent will be accepted as valid packets. This value is set in the AgentParameters class and is only valid for SNMP v1 and v2c requests.

protected bool _noSourceCheck
Результат	bool

_socket защищенное свойство

Socket

protected Socket _socket
Результат	Socket
