Trace 的使用

Listener objects:

1. DefaultTraceListener class

2. TextWriterTraceListener class

3. XmlWriterTraceListener class

4. EventLogTraceListener class

5. DelimitedListTraceListener class

//Config

<? xml version = " 1.0 "  encoding = " utf-8 "   ?>
< configuration >
< system.diagnostics >
< trace autoflush = " true "  indentsize = " 5 " >
< listeners >
< add name = " DemoListener "  type = " System.Diagnostics.XmlWriterTraceListener "
initializeData = " output.xml "   />
< remove name = " Default "   />
</ listeners >
</ trace >
</ system.diagnostics >
</ configuration >

//Code

 

 

Trace.Listeners.Clear();
XmlWriterTraceListener MyListener  =   new  XmlWriterTraceListener ( @" C:\output.xml " );
Trace.Listeners.Add(MyListener);
Trace.AutoFlush  =   true ;
Trace.WriteLine( " This is a test " );

//Code2 

Trace.Listeners.Clear();
EventLogTraceListener MyListener  =   new  EventLogTraceListener ( " Chapter10 " );
Trace.Listeners.Add(MyListener);
Trace.AutoFlush  =   true ;
Trace.WriteLine( " Something happened " );
