	TraceEventCache eventCache,
	string source,
	TraceEventType eventType,
	int id,
	string format,

)

Parameters

eventCache
Type: System.Diagnostics.TraceEventCache

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

source
Type: System.String

The source name.

eventType
Type: System.Diagnostics.TraceEventType

One of the TraceEventType values.

id
Type: System.Int32

A numeric identifier for the event.

format
Type: System.String

A format string that contains zero or more format items that correspond to objects in the args array.

args
Type: System.Object[]

An object array that contains zero or more objects to format.

The eventCache, source, eventType, and id parameters are used in the header and footer of the trace. The id parameter is converted to an unsigned integer before it is written. Therefore, a negative id value is written as a large positive integer. The String.Format(String, Object[]) method is called and the format string and args array are passed in as parameters. This method formats the args object array and writes the formatted array as the Data node in the EventData element.

System_CAPS_importantImportant

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