参考答案：A
注释：
The WriteLine method of the Trace class writes a string to the event log specified by the EventLog property of an EventLog TraceListener object.The ToString method returns a string representation of the Trace object.The WriteIndent method of the TraceListener class places an indent,or tab,into the listener.The TextWriter class is used to write characters to a file;therefore,id does not meet the requirement of the scenario.
