A Stream with no backing store.

Assembly: mscorlib (in mscorlib.dll)

Public Shared ReadOnly Null As Stream

public static readonly Stream Null

public:
static initonly Stream^ Null

static val Null: Stream

Remarks

Use Null to redirect output to a stream that will not consume any operating system resources. When the methods of Stream that provide writing are invoked on Null, the call simply returns, and no data is written. Null also implements a Read method that returns zero without reading data.
