Public Shared ReadOnly Null As StreamWriter
Field Value
Examples
The following example demonstrates a use of the Null
field.
if ( sw->Equals( StreamWriter::Null ) )
{
sw->WriteLine( "The store can be written to, but not read from." );
}
if(sw.Equals(StreamWriter.Null))
{
sw.WriteLine("The store can be written to, but not read from.");
}
If Sw.Equals(StreamWriter.Null) Then
Sw.WriteLine("The store can be written to, but not read from.")
End If
Remarks
Use Null
to redirect output to a StreamWriter
that will not consume any operating system resources.
When the StreamWriter.Write
methods are invoked on Null
, the call simply returns, and no data is actually written to any backing store.
