DefaultTraceListener

DefaultTraceListenerCF 1.0, marshal by reference, disposable

System.Diagnostics (system.dll)class

This class provides the default TraceListener. By default, an instance of this class is available in the Listeners collection of the Debug and Trace classes. The Write( ) and WriteLine( ) methods output to the log and to the active debugger (if any) via the Win32 API function OutputDebugString. The log file is initially unset, so output goes only to the debugger. To specify a log file, set LogFileName. You may also set a logfile in the <assert> element of the application configuration file's <system.diagnostics> section, as in <assert logfilename="logfile.log"/>.

AssertUiEnabled determines whether to use the user interface for failed assertions. If true, .NET uses a dialog box with the options Abort, Retry, or Fail. Whether this property is set to true or false, .NET always writes messages to the LogFileName, if one is specified. The AssertUiEnabled property can be set using the <assert> element, as in <assert assertuienabled="false"/> (the default is true).
