TraceSource Constructor (String, SourceLevels)

Initializes a new instance of the TraceSource class, using the specified name for the source and the default source level at which tracing is to occur.

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

public TraceSource(
	string name,
	SourceLevels defaultLevel
)

Parameters

name
Type: System.String

The name of the source, typically the name of the application.

defaultLevel
Type: System.Diagnostics.SourceLevels

A bitwise combination of the SourceLevels values that specifies the default source level at which to trace.

ExceptionCondition
ArgumentNullException

name is null.

ArgumentException

name is an empty string ("").

The source name is used to identify traces. It can be used by a SourceSwitch to determine if tracing is to occur and by a SourceFilter to determine whether to produce the trace. The default source level is used by an EventTypeFilter to determine if tracing is to occur based on the source level of the message to be traced.

NoteNote:

It is not necessary to create a new TraceSource instance for each trace request. Create one TraceSource instance and use it for all trace requests for the application.
