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);
