When the disposing parameter is true, this method releases all resources held by any managed objects that this StreamWriter references. This method invokes the Dispose method of each referenced object.
Notes to Inheritors
Dispose can be called multiple times by other objects. When overriding Dispose, be careful not to reference objects that have been previously disposed in an earlier call to Dispose.
