Specifies the levels of trace messages filtered by the source switch and event type filter.
Syntax
public enum SourceLevels
Remarks
The source levels identify the System.Diagnostics.TraceEventType events that are to be traced. The System.Diagnostics.SourceSwitch class uses the System.Diagnostics.SourceLevels enumeration to define the event level of the trace message to use for filtering messages to send to the trace listener.
The System.Diagnostics.EventTypeFilter class uses the System.Diagnostics.SourceLevels enumeration to determine whether a trace listener should emit a trace.
