The name of the trace source.

Examples

The following code example calls the TraceData method using two different source filters, one with a fictitious name, the other with the name of the current trace source. In the first case, the trace is not written to the console; in the second case, the trace is written. 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.Information, 5,
    "SourceFilter should reject this message for the console trace listener.");
ts.Listeners["console"].Filter = new SourceFilter("TraceTest");
ts.TraceData(TraceEventType.Information, 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.Information, 5, "SourceFilter should reject this message for the console trace listener.")
ts.Listeners("console").Filter = New SourceFilter("TraceTest")
ts.TraceData(TraceEventType.Information, 6, "SourceFilter should let this message through on the console trace listener.")

Remarks

The value of the source parameter is used to initialize the Source property.
