在C＃中将调试消息记录到控制台

Question

I have a very very basic c# question about logging debug-trace messages on console. For redirecting the trace message to console, we can use

    Trace.Listeners.Add(new ConsoleTraceListener());

I was expecting something similar to exist for logging debug message to console.

    //Debug.Listeners.Add(new ConsoleDebugListener()); //does not exist
    Debug.Listeners.Add(new ConsoleTraceListener());

so the name does not make a difference or am i missing something.

EDIT

I just wanted to know if something like ConsoleDebugListener or something similar exist or not. it works with trace listener though.

Answer 1

The ConsoleTraceListener is a class that handles how to write messages coming its way; even though it contains Trace it is not the exclusive output method for the Trace class in the System.Diagnostics namespace.

If you want to really find why the ConsoleTraceListener works for both Debug and Trace , it is because both of them use the TraceInternal class internally, which then sends messages to the listeners it contains. Maybe that's a good enough reason for the initial listeners to have been called *Trace* ( EventLogTraceListener , XmlWriterTraceListener , etc...)

Interestingly, listeners are shared between Debug and Trace since they both return the TraceInternal property.
