Provides a TextWriter with no backing store that can be written to, but not read from.
Assembly: mscorlib (in mscorlib.dll)
Use Null to redirect output to a stream that will not consume any operating system resources.
When the TextWriter.Write methods are invoked on Null, the call simply returns, and no data is actually written to any backing store.
