Hello,

I need to us a TextWriter as an argument of a method:

System.IO.TextWriter t;
_parser.Go(t);

However I get, on the second line, the error:
Use of unassigned local variable 't'

But I am not able to do the following:
System.IO.TextWriter t = new TextWriter();

How can I solve this?

Thanks,
Miguel

TextWriter is abstract. You can use StreamWriter, or some other class
that extends TextWriter.

TextWriter is an abstract class so you can't instantiate it. You must
use one of the derived classes such as StreamWriter and StringWriter.

RTFM. TextWriter is abstract; you can't create instances of it. Create a
StreamWriter.

Reading The Fantastic Manual may be a good idea, indeed. :)
