DelimitedListTraceListener Class

The trace output is in a delimited text format that uses the delimiter specified by the Delimiter property. The delimiter is used to terminate each field in a line of output. For example, to display the trace output in a Microsoft Excel spreadsheet, you might specify a comma (",") as a delimiter and create a comma-separated value (CSV) file.

You can enable or disable a DelimitedListTraceListener through the application configuration file and then use the configured DelimitedListTraceListener in your application. Alternately, you can create a DelimitedListTraceListener in your code.

Note
The DelimitedListTraceListener delimits only text that is emitted by using the methods that have names starting with the word Trace, such as DelimitedListTraceListener.TraceEvent or Trace.TraceWarning. Trace data that is emitted by using the Debug.Write and TextWriterTraceListener.WriteLine methods is not delimited.

To configure a DelimitedListTraceListener, edit the configuration file that corresponds to the name of your application. In this file, you can add a listener, set the properties for a listener, or remove a listener. The configuration file should be formatted as shown in the following example:

<configuration>
  <system.diagnostics>
    <trace autoflush="false" indentsize="4">
      <listeners>
        <add name="delimitedListener" 
          type="System.Diagnostics.DelimitedListTraceListener" 
          delimiter="," 
          initializeData="delimitedOutput.csv" 
          traceOutputOptions="ProcessId, DateTime" />
      </listeners>
    </trace>
  </system.diagnostics>
</configuration>

Note
If you try to write to a file that is in use or unavailable, the file name is automatically prefixed by a GUID.

Note
Listeners are intended to be used by methods of the Debug, Trace, and TraceSource classes to write trace information. Listener methods, except for constructors, should not be called directly from application code.

Note

The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: Synchronization. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
