TextWriter::Null Field

Provides a TextWriter with no backing store that can be written to, but not read from.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

public:
static initonly TextWriter^ Null

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.
