| <H4 class="dtH4">Thread Safety</H4> |
| <P>Public static (<b>Shared</b> in Visual Basic) members of this type are |
| safe for multithreaded operations. Instance members are <b>not</b> guaranteed to be |
| thread-safe.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> UDP guarantees neither that messages arrive, nor that they arrive in the correct order. </p> |
| <p> To view the logging results, a custom application can be developed that listens for logging events. </p> |
| <p> When decoding events send via this appender remember to use the same encoding to decode the events as was used to send the events. See the <a href="log4net.Appender.UdpAppender.Encoding.html">Encoding</a> property to specify the encoding to use. </p> |
| <h4 class="dtH4">Example</h4><p> This example shows how to log receive logging events that are sent on IP address 244.0.0.1 and port 8080 to the console. The event is encoded in the packet as a unicode string and it is decoded as such. <pre class="code"><span class="lang">[C#] |
| </span>IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Any, 0); |
| UdpClient udpClient; |
| byte[] buffer; |
| string loggingEvent; |
| |
| try |
| { |
| udpClient = new UdpClient(8080); |
| |
| while(true) |
| { |
| buffer = udpClient.Receive(ref remoteEndPoint); |
| loggingEvent = System.Text.Encoding.Unicode.GetString(buffer); |
| Console.WriteLine(loggingEvent); |
| } |
| } |
| catch(Exception e) |
| { |
| Console.WriteLine(e.ToString()); |
| } |
| </pre> |
| <pre class="code"><span class="lang">[Visual�Basic] |
| </span> Dim remoteEndPoint as IPEndPoint |
| Dim udpClient as UdpClient |
| Dim buffer as Byte() |
| Dim loggingEvent as String |
| |
| Try |
| remoteEndPoint = new IPEndPoint(IPAddress.Any, 0) |
| udpClient = new UdpClient(8080) |
| |
| While True |
| buffer = udpClient.Receive(ByRef remoteEndPoint) |
| loggingEvent = System.Text.Encoding.Unicode.GetString(buffer) |
| Console.WriteLine(loggingEvent) |
| Wend |
| Catch e As Exception |
| Console.WriteLine(e.ToString()) |
| End Try |
