TraceSource.TraceData Method

Definition

Writes trace data to the trace listeners in the Listeners collection.

Overloads

TraceData(TraceEventType, Int32, Object)

Writes trace data to the trace listeners in the Listeners collection using the specified event type, event identifier, and trace data.

TraceData(TraceEventType, Int32, Object[])

Writes trace data to the trace listeners in the Listeners collection using the specified event type, event identifier, and trace data array.

TraceData(TraceEventType, Int32, Object)

Source:
TraceSource.cs
Source:
TraceSource.cs
Source:
TraceSource.cs

Writes trace data to the trace listeners in the Listeners collection using the specified event type, event identifier, and trace data.

public:
 void TraceData(System::Diagnostics::TraceEventType eventType, int id, System::Object ^ data);
[System.Diagnostics.Conditional("TRACE")]
public void TraceData (System.Diagnostics.TraceEventType eventType, int id, object? data);
[System.Diagnostics.Conditional("TRACE")]
public void TraceData (System.Diagnostics.TraceEventType eventType, int id, object data);
[<System.Diagnostics.Conditional("TRACE")>]
member this.TraceData : System.Diagnostics.TraceEventType * int * obj -> unit
Public Sub TraceData (eventType As TraceEventType, id As Integer, data As Object)

Parameters

eventType
TraceEventType

One of the enumeration values that specifies the event type of the trace data.

id
Int32

A numeric identifier for the event.

data
Object

The trace data.

Attributes

Exceptions

An attempt was made to trace an event during finalization.

Examples

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.

// Test the filter on the ConsoleTraceListener.
ts.Listeners["console"].Filter = new SourceFilter("No match");
ts.TraceData(TraceEventType.Error, 5,
    "SourceFilter should reject this message for the console trace listener.");
ts.Listeners["console"].Filter = new SourceFilter("TraceTest");
ts.TraceData(TraceEventType.Error, 6,
    "SourceFilter should let this message through on the console trace listener.");
' Test the filter on the ConsoleTraceListener.
ts.Listeners("console").Filter = New SourceFilter("No match")
ts.TraceData(TraceEventType.Error, 5, "SourceFilter should reject this message for the console trace listener.")
ts.Listeners("console").Filter = New SourceFilter("TraceTest")
ts.TraceData(TraceEventType.Error, 6, "SourceFilter should let this message through on the console trace listener.")

Remarks

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.

Writes trace data to the trace listeners in the Listeners collection using the specified event type, event identifier, and trace data array.

public:
 void TraceData(System::Diagnostics::TraceEventType eventType, int id, ... cli::array <System::Object ^> ^ data);
[System.Diagnostics.Conditional("TRACE")]
public void TraceData (System.Diagnostics.TraceEventType eventType, int id, params object?[]? data);

[<System.Diagnostics.Conditional("TRACE")>]
member this.TraceData : System.Diagnostics.TraceEventType * int * obj[] -> unit
Public Sub TraceData (eventType As TraceEventType, id As Integer, ParamArray data As Object())

Parameters

eventType
TraceEventType

One of the enumeration values that specifies the event type of the trace data.

id
Int32

A numeric identifier for the event.

data
Object[]

An object array containing the trace data.

Attributes

Exceptions

An attempt was made to trace an event during finalization.

Remarks

The TraceData method, like the TraceEvent method, is intended for automated tools, but it also allows the attaching of additional objects, such as an exception instance and a stack trace, to the trace.

The TraceData method calls the 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.
