TraceFilter Class
Provides the base class for trace filter implementations.
System.Diagnostics.TraceFilter
System.Diagnostics.EventTypeFilter
System.Diagnostics.SourceFilter
Assembly: System (in System.dll)
The TraceFilter type exposes the following members.
| Name | Description | |
|---|---|---|
|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ShouldTrace | When overridden in a derived class, determines whether the trace listener should trace the event. |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
Trace filters can be used by trace listeners to provide an extra layer of filtering beyond that provided by trace switches. The trace filter for a trace listener can be found in the listener's Filter property. Trace switches determine if a trace is to be sent to the trace listeners. Trace filters allow the individual trace listeners to determine whether or not the trace is to be written to the associated output medium. For example, as determined by each trace filter, a trace may be written to the console by a ConsoleTraceListener, but not to the event log by a EventLogTraceListener.
Filters that inherit from the TraceFilter class can be used by trace listeners that inherit from the TraceListener class to perform filtering of events being traced. TraceFilter contains a single method, ShouldTrace, which takes event data and returns a flag indicating whether the event should be traced.
