SourceFilter Constructor

Initializes a new instance of the SourceFilter class, specifying the name of the trace source.

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

public SourceFilter(
	string source
)

Parameters

source
Type: System.String

The name of the trace source.

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

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.");
