This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.Namespace: System.Diagnostics
Assembly: System (in system.dll)
|Callstack||Write the call stack, which is represented by the return value of the Environment.StackTrace property.|
|DateTime||Write the date and time.|
|LogicalOperationStack||Write the logical operation stack, which is represented by the return value of the CorrelationManager.LogicalOperationStack property.|
|None||Do not write any elements.|
|ProcessId||Write the process identity, which is represented by the return value of the Process.Id property.|
|ThreadId||Write the thread identity, which is represented by the return value of the Thread.ManagedThreadId property for the current thread.|

This enumeration is used by trace listeners to determine which options, or elements, should be included in the trace output. Trace listeners store the trace options in the TraceOutputOptions property.
The following example shows the use of the traceOutputOptions attribute to specify the trace output options for a ConsoleTraceListener that is enabled using a configuration file.
<configuration> <system.diagnostics> <trace autoflush="false" indentsize="4"> <listeners> <add name="consoleListener" type="System.Diagnostics.ConsoleTraceListener" traceOutputOptions="ProcessId, DateTime" /> </listeners> </trace> </system.diagnostics> </configuration>
For details about adding trace listeners in the application configuration file, see <listeners> Element for <trace>.
The following code example shows the use of the TraceOptions enumeration to programmatically set the TraceOutputOptions property for a console trace listener. The console trace listener is one of the listeners enumerated in the Listeners property of a trace source. This code example is part of a larger example provided for the TraceSource class.
