)

Parameters

eventCache
Type: System.Diagnostics.TraceEventCache
A TraceEventCache object that contains the current process ID, thread ID, and stack trace information.
source
Type: System.String
A name used to identify the output, typically the name of the application that generated the trace event.
eventType
Type: System.Diagnostics.TraceEventType
One of the TraceEventType values specifying the type of event that has caused the trace.
id
Type: System.Int32
A numeric identifier for the event.
format

args

Important noteImportant

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 args object array is converted to a string using the Format method, passing the format string and args array to format the string as the message portion of the trace. The eventCache data is written as a footer, the nature of the output data being dependent on the value of the TraceOutputOptions property.
