TraceSource Constructor (String)

Initializes a new instance of the TraceSource class, using the specified name for the source.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)
public TraceSource(
	string name
)

Parameters

name
Type: System.String

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

ExceptionCondition
ArgumentNullException

name is null.

ArgumentException

name is an empty string ("").

The source name is used to identify traces. It is used by a SourceFilter to determine whether a trace listener should produce the trace. The recommended practice is to use the name of the application for the source name.

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.

The following code example shows the use of the TraceSource constructor to create a new TraceSource object. This code example is part of a larger example provided for the TraceSource class.

// Initialize the trace source. 
static TraceSource ts = new TraceSource("TraceTest");
