DelimitedListTraceListener Class

Note: This class is new in the .NET Framework version 2.0.

Directs tracing or debugging output to a text writer, such as a stream writer, or to a stream, such as a file stream.

Namespace: System.Diagnostics
Assembly: System (in system.dll)

public class DelimitedListTraceListener : TextWriterTraceListener
public class DelimitedListTraceListener extends TextWriterTraceListener
public class DelimitedListTraceListener extends TextWriterTraceListener

NoteNote

The HostProtectionAttribute attribute applied to this class 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.

The trace output is in a delimited text format that uses the delimiter specified by the Delimiter property.

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.

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 like the following example:

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

If an attempt is made to write to a file that is in use or unavailable, the file name is automatically prefixed by a GUID.

NoteNote

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