How do I silence Console.Writeline?

deanebarker

I'm using a library that -- for whatever reason -- has decided to write warnings to Console.Writeline. This means it constantly clutters up my Results pane with its internal nonsense.

This is coming from somewhere deep inside this library. I cannot change it.

How do I somehow prevent it from writing anything to the results?

If you don't mind losing the output of any Console.Writes or Console.WriteLines in your linqpad script, then you can redirect the output to null, e.g.

Console.SetOut(TextWriter.Null);

This sounded wonderful, but it taught me that they must not being using Console.Writeline, because it didn't stop the messages.

How else could a library be writing to my results like this?

Here's the line from the SQLite source:

sqlite3_log(SQLITE_NOTICE,
      "delayed %dms for lock/sharing conflict at line %d",
      winIoerrRetryDelay*nRetry*(nRetry+1)/2, lineno
    );

I followed that method call, and it looks like it's just doing printf from the C code.

Something else you can try is

Trace.Listeners.Clear();

That did it. Thank you.
