TraceSource记录程序日志

1.配置文件

 <system.diagnostics>
     <sources>
       <source name="TraceError" switchValue="Error,ActivityTracing,Information">
         <listeners>

           <add initializeData="./clog.txt" type="System.Diagnostics.TextWriterTraceListener, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
                         name="txtListener" traceOutputOptions="DateTime,ProcessId,ThreadId" >
             <filter type="System.Diagnostics.EventTypeFilter" initializeData="Error,Information" />
           </add>
         </listeners>
       </source>
     </sources>
     <trace autoflush="true">
     </trace>
   </system.diagnostics>

2.实例化TraceSource

public TraceSource _ts = new TraceSource("TraceError");

3.在需要记录日志的地方这样写

_ts.TraceData(TraceEventType.Information, 0, Message);
