Writes trace information, a message, and event information to the event log.
public:
override void TraceEvent(System::Diagnostics::TraceEventCache ^ eventCache, System::String ^ source, System::Diagnostics::TraceEventType severity, int id, System::String ^ message);
[System.Runtime.InteropServices.ComVisible(false)]
public override void TraceEvent (System.Diagnostics.TraceEventCache eventCache, string source, System.Diagnostics.TraceEventType severity, int id, string message);
[<System.Runtime.InteropServices.ComVisible(false)>]
override this.TraceEvent : System.Diagnostics.TraceEventCache * string * System.Diagnostics.TraceEventType * int * string -> unit
Public Overrides Sub TraceEvent (eventCache As TraceEventCache, source As String, severity As TraceEventType, id As Integer, message As String)
Parameters
- eventCache
- TraceEventCache
An object that contains the current process ID, thread ID, and stack trace information.
- source
- String
A name used to identify the output; typically the name of the application that generated the trace event.
- severity
- TraceEventType
One of the enumeration values that specifies the type of event that has caused the trace.
- id
- Int32
A numeric identifier for the event. The combination of source
and id
uniquely identifies an event.
- message
- String
The trace message.
- Attributes

Remarks
Important
The TraceEvent methods are not intended to be called by application code. These methods are called by methods of the Debug, Trace, and TraceSource classes to write trace data.
The TraceEvent method is intended to trace events that can be processed automatically by tools. For example a monitoring tool can notify an administrator if a specific event is traced by a specific source.
The eventCache
and source
parameters are used to determine if the event should be traced. id
is used to create an EventInstance object and the TraceEventType is equated to an EventLogEntryType for the EntryType property. The EventInstance is written to the event log with the message
data using the WriteEvent method.
Note
The maximum value of the id
parameter is 65,535. If the id
value specified is greater than 65,535, the maximum value is used.

Public Overrides Sub TraceEvent (eventCache As TraceEventCache, source As String, severity As TraceEventType, id As Integer, format As String, ParamArray args As Object())
Parameters
- eventCache
- TraceEventCache
An object that contains the current process ID, thread ID, and stack trace information.
- source
- String
A name used to identify the output; typically the name of the application that generated the trace event.
- severity
- TraceEventType
One of the enumeration values that specifies the type of event that has caused the trace.
- id
- Int32
A numeric identifier for the event. The combination of source
and id
uniquely identifies an event.
- format
- String
A format string that contains zero or more format items that correspond to objects in the args
array.
- args
- Object[]
An object
array containing zero or more objects to format.

The TraceEvent method is intended to trace events that can be processed automatically by tools. For example a monitoring tool can notify an administrator if a specific event is traced by a specific source.
The eventCache
and source
parameters are used to determine if the event should be traced. id
is used to create an EventInstance object and the TraceEventType is equated to an EventLogEntryType for the EntryType property. The EventInstance is written to the event log, using the WriteEvent method, with the message obtained from the format
and args
parameters. 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 for the event log.
Note
The maximum value of the id
parameter is 65,535. If the id
value specified is greater than 65,535, the maximum value is used.
