| <H4 class="dtH4">Thread Safety</H4> |
| <P>This type is safe for multithreaded operations.</P> |
| <h4 class="dtH4">Remarks</h4> |
| <p> The <code>ThreadContext</code> provides a location for thread specific debugging information to be stored. The <code>ThreadContext</code> properties override any <a href="log4net.GlobalContext.html">GlobalContext</a> properties with the same name. </p> |
| <p> The thread context has a properties map and a stack. The properties and stack can be included in the output of log messages. The <a href="log4net.Layout.PatternLayout.html">PatternLayout</a> supports selecting and outputting these properties. </p> |
| <p> The Thread Context provides a diagnostic context for the current thread. This is an instrument for distinguishing interleaved log output from different sources. Log output is typically interleaved when a server handles multiple clients near-simultaneously. </p> |
| <p> The Thread Context is managed on a per thread basis. </p> |
| <h4 class="dtH4">Example</h4><p>Example of using the thread context properties to store a username. <pre class="code"><span class="lang">[C#] |
| </span>ThreadContext.Properties["user"] = userName; |
| log.Info("This log message has a ThreadContext Property called 'user'"); |
| </pre> |
| Example of how to push a message into the context stack <pre class="code"><span class="lang">[C#] |
| </span>using(ThreadContext.Stacks["NDC"].Push("my context message")) |
| { |
| log.Info("This log message has a ThreadContext Stack message that includes 'my context message'"); |
| |
| } // at the end of the using block the message is automatically popped |
| </pre> |
