Reference

for RuBoard

This section provides a quick reference to the key objects described in this chapter. Space constraints prevent us from documenting every object in the .NET framework in this book. For the sake of brevity and conciseness, we include only the most important objects here. For more information on the other objects in the .NET framework, consult the .NET Framework Reference online help file.

This chapter covers the debugging, performance-monitoring, and event-logging classes in ASP.NET. The following sections provide a brief reference to the properties, methods , and events provided by those classes.

Debug Class

Member of System.Diagnostics.

The Debug object gives developers access to a number of useful tools to manage the debugging process.

It is not necessary to instantiate a Debug object; an instance of the object is always available in an ASP.NET page.

Properties
AutoFlush	IndentSize
IndentLevel	Listeners
Methods
Assert	Indent	WriteLine
Close	Unindent	WriteLineIf
Fail	Write
Flush	WriteIf

EventLog Class

Member of System.Diagnostics.

The EventLog class is used to read and write information from the Windows event log. This is used primarily to record diagnostic information pertaining to an application, particularly failure information.

Properties
Container	Events	Site
DesignMode	Log	Source
EnableRaisingEvents	LogDisplayName	SynchronizingObject
Entries	MachineName
Methods
BeginInit	EndInit	InitializeLifetimeService
Clear	Equals	LogNameFromSourceName
Close	Exists	MemberwiseClone
CreateEventSource	Finalize	SourceExists
CreateObjRef	GetEventLogs	ToString
Delete	GetHashCode	WriteEntry
DeleteEventSource	GetLifetimeService
Dispose	GetService
	GetType
Events
Disposed	EntryWritten

PerformanceCounter Class

Member of System.Diagnostics.

You create an instance of this class to expose your application's performance information to performance monitors .

Properties
CategoryName	CounterType	MachineName
Container	DesignMode	RawValue
CounterHelp	Events	ReadOnly
CounterName	InstanceName	Site
Methods
BeginInit	Equals	InitializeLifetimeService
Close	Finalize	MemberwiseClone
CloseSharedResource	GetHashCode	NextSample
CreateObjRef	GetLifetimeService	NextValue
Decrement	GetService	RemoveInstance
Dispose	GetType	ToString
	Increment
EndInit	IncrementBy
Events
Disposed

TraceContext Class

Member of System.Web.

TraceContext provides Trace mode functionality in ASP.NET Web application development. It is typically accessed as the Trace object contained by the ASP.NET Page object.

Properties
IsEnabled	TraceMode
Methods
Equals	GetType	Warn
Finalize	MemberwiseClone	Write
GetHashCode	ToString
