Parameters
traceWriter
Type: System.Web.Http.Tracing.ITraceWriterThe ITraceWriter.
request
Type: HttpRequestMessageThe HttpRequestMessage with which to associate the trace. It may be null.
category
Type: System.StringThe logical category of the trace.
level
Type: System.Web.Http.Tracing.TraceLevelThe TraceLevel of the trace.
operatorName
Type: System.StringThe name of the object performing the operation. It may be null.
operationName
Type: System.StringThe name of the operation being performed. It may be null.
beginTrace
Type: System.Action<TraceRecord>The Action to invoke prior to performing the operation, allowing the given TraceRecord to be filled in. It may be null.
execute
Type: System.ActionAn <see cref="T:System.Func`1" /> that returns the Task that will perform the operation.
endTrace
Type: System.Action<TraceRecord>The Action to invoke after successfully performing the operation, allowing the given TraceRecord to be filled in. It may be null.
errorTrace
Type: System.Action<TraceRecord>The Action to invoke if an error was encountered performing the operation, allowing the given TraceRecord to be filled in. It may be null.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type ITraceWriter. When you use instance method syntax to call this method, omit the first parameter.
