	params Object[] data
/** @attribute ComVisibleAttribute(false) */ 
public void TraceData (

	Object[] data
public function TraceData (
	eventCache : TraceEventCache,

	eventType : TraceEventType, 
	id : int, 
	... data : Object[]
Not applicable.



A TraceEventCache object that contains the current process ID, thread ID, and stack trace information.


A name used to identify the output, typically the name of the application that generated the trace event.


One of the TraceEventType values specifying the type of event that has caused the trace.


A numeric identifier for the event.


An array of objects to emit as data.


This method is not intended to be called directly by application code but by members of the Debug, Trace, and TraceSource classes to write trace data to output.

The default implementation writes the values of the source, eventType and id parameters as a header. The data objects are converted to strings using the ToString method of each object. The eventCache data is written as a footer, the nature of the output data being dependent on the value of the TraceOutputOptions property.
