Gets a collection of TraceContextRecord messages that are associated with the current request.
Assembly: System.Web (in System.Web.dll)
Every call to the TraceContext::Write and TraceContext::Warn methods generates a TraceContextRecord object that is added to the messages collection. The Warn method call sets the IsWarning property to true, while the other method calls set it to false.
You can iterate through the messages and examine records with specific categories or messages, and whether they are warnings.

The following code example demonstrates how you can register a TraceContextEventHandler delegate to handle the TraceFinished event. In this example, the OnTraceFinished method accesses the collection of TraceContextRecord objects through the property, iterates through them, and writes them to the response stream.
