TraceOptions TraceOptions TraceOptions TraceOptions Enum


Specifies trace data options to be written to the trace output.

This enumeration has a FlagsAttribute attribute that allows a bitwise combination of its member values.

public enum class TraceOptions
public enum TraceOptions
type TraceOptions = 
Public Enum TraceOptions


Callstack Callstack Callstack Callstack 32

Write the call stack, which is represented by the return value of the StackTrace property.

DateTime DateTime DateTime DateTime 2

Write the date and time.

LogicalOperationStack LogicalOperationStack LogicalOperationStack LogicalOperationStack 1

Write the logical operation stack, which is represented by the return value of the LogicalOperationStack property.

None None None None 0

Do not write any elements.

ProcessId ProcessId ProcessId ProcessId 8

Write the process identity, which is represented by the return value of the Id property.

ThreadId ThreadId ThreadId ThreadId 16

Write the thread identity, which is represented by the return value of the ManagedThreadId property for the current thread.

Timestamp Timestamp Timestamp Timestamp 4

Write the timestamp, which is represented by the return value of the GetTimestamp() method.


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.

ts.Listeners["console"].TraceOutputOptions |= TraceOptions.Callstack;
ts.Listeners("console").TraceOutputOptions = ts.Listeners("console").TraceOutputOptions Or TraceOptions.Callstack


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.

    <trace autoflush="false" indentsize="4">  
        <add name="consoleListener"  
          traceOutputOptions="ProcessId, DateTime" />  

For details about adding trace listeners to the application configuration file, see <listeners>.

The TraceOptions enumeration is not used by the following classes and methods:
