TraceSource::TraceData Method (TraceEventType, Int32, Object^)
Writes trace data to the trace listeners in the Listeners collection using the specified event type, event identifier, and trace data.
Assembly: System (in System.dll)
public: [ConditionalAttribute("TRACE")] void TraceData( TraceEventType eventType, int id, Object^ data )
Parameters
- eventType
-
Type:
System.Diagnostics::TraceEventType
One of the enumeration values that specifies the event type of the trace data.
- id
-
Type:
System::Int32
A numeric identifier for the event.
- data
-
Type:
System::Object^
The trace data.
| Exception | Condition |
|---|---|
| ObjectDisposedException | An attempt was made to trace an event during finalization. |
The TraceData method, like the TraceEvent method, is intended for automated tools, but it also allows the attaching of an additional object, such as an exception instance, to the trace.
The TraceData method calls the SourceSwitch::ShouldTrace method of the SourceSwitch object returned by the Switch property. If ShouldTrace returns true, TraceData calls the corresponding TraceData method on all listeners. Otherwise, TraceData returns without calling the listeners' methods.
Note |
|---|
The EventLogTraceListener object is limited to a maximum id value of 65,535. If the id value specified is greater than 65,535, the EventLogTraceListener object uses 65,535. |
The following code example shows the use of the TraceData(TraceEventType, Int32, Object^) method to filter and forward a trace message to the listeners. This code example is part of a larger example provided for the TraceSource class.
