EventSchemaTraceListener.TraceData Method (TraceEventCache, String, TraceEventType, Int32, Object)


Writes trace information, a single data object, and event information to the log file.

Namespace:   System.Diagnostics
Assembly:  System.Core (in System.Core.dll)

public override void TraceData(
	TraceEventCache eventCache,
	string source,
	TraceEventType eventType,
	int id,
	object data


Type: System.Diagnostics.TraceEventCache

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

Type: System.String

The source name.

Type: System.Diagnostics.TraceEventType

One of the TraceEventType values.

Type: System.Int32

A numeric identifier for the event.

Type: System.Object

A data object to emit.

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 data parameter is written as a Data node in the UserData element. The ToString method of the data object is used to convert the object to a string.


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.
