Writes trace data to the output file.

Overloads

TraceData(TraceEventCache, String, TraceEventType, Int32, Object)	Writes trace information, a data object, and event information to the output file or stream.
TraceData(TraceEventCache, String, TraceEventType, Int32, Object[])	Writes trace information, an array of data objects, and event information to the output file or stream.

Remarks

TraceData methods are not intended to be called by application code. These methods are called by members of the Debug, Trace, and TraceSource classes to write trace data to output.

TraceData(TraceEventCache, String, TraceEventType, Int32, Object)

Writes trace information, a data object, and event information to the output file or stream.

public:
 override void TraceData(System::Diagnostics::TraceEventCache ^ eventCache, System::String ^ source, System::Diagnostics::TraceEventType eventType, int id, System::Object ^ data);

public override void TraceData (System.Diagnostics.TraceEventCache eventCache, string source, System.Diagnostics.TraceEventType eventType, int id, object data);

override this.TraceData : System.Diagnostics.TraceEventCache * string * System.Diagnostics.TraceEventType * int * obj -> unit

Public Overrides Sub TraceData (eventCache As TraceEventCache, source As String, eventType As TraceEventType, id As Integer, data As Object)

Parameters

eventCache: TraceEventCache

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

source: String

A name of the trace source that invoked this method.

eventType: TraceEventType

One of the TraceEventType enumeration values.

id: Int32

A numeric identifier for the event.

data: Object

The trace data to emit.

Remarks

This method:

Formats the data and context information for output.
Creates a new log file, if necessary.
Writes the information to the log file.

For more information on creating new log files, see FullLogFileName.

The following table lists the output fields in the order they appear. The fields are delimited by the string that the Delimiter property specifies, and are followed by a line terminator.

Field	Output condition	Description
`source`	Always	The value of `name`.
`severity`	Always	The enumeration-value name of `eventType`.
`id`	Always	The string representation of `id`.
`message`	Always	The string representation of `data`.
`callStack`	When the Callstack flag is set in the TraceOutputOptions property.	The Callstack property of `eventCache`.
`CorrelationID`	When the LogicalOperationStack flag is set in the TraceOutputOptions property.	The ThreadId property of `eventCache`.
`DateTime`	When the DateTime flag is set in the TraceOutputOptions property.	The string representation of the DateTime property of `eventCache`. The invariant culture is used for the string conversion.
`ProcessID`	When the ProcessId flag is set in the TraceOutputOptions property.	The string representation of the ProcessId property of `eventCache`. The invariant culture is used for the string conversion.
`ThreadID`	When the ThreadId flag is set in the TraceOutputOptions property.	The ThreadId property of `eventCache`.
`Timestamp`	When the Timestamp flag is set in the TraceOutputOptions property.	The string representation of the Timestamp property of `eventCache`. The invariant culture is used for the string conversion.
`HostName`	When the IncludeHostName property is `True`.	The name of the computer.

Applies to

TraceData(TraceEventCache, String, TraceEventType, Int32, Object[])

Writes trace information, an array of data objects, and event information to the output file or stream.

public:
 override void TraceData(System::Diagnostics::TraceEventCache ^ eventCache, System::String ^ source, System::Diagnostics::TraceEventType eventType, int id, ... cli::array <System::Object ^> ^ data);

public override void TraceData (System.Diagnostics.TraceEventCache eventCache, string source, System.Diagnostics.TraceEventType eventType, int id, params object[] data);

override this.TraceData : System.Diagnostics.TraceEventCache * string * System.Diagnostics.TraceEventType * int * obj[] -> unit

Public Overrides Sub TraceData (eventCache As TraceEventCache, source As String, eventType As TraceEventType, id As Integer, ParamArray data As Object())

Parameters

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

source: String

The name of the trace source that invoked this method.

eventType: TraceEventType

One of the TraceEventType enumeration values.

id: Int32

A numeric identifier for the event.

data: Object[]

An array of objects to emit as data.

Remarks

This method:

Formats the data and context information for output,
Creates a new log file, if necessary,
Writes the information to the log file.
