[Mono-list] Re: XmlTextWriter bugs

[eric lindvall]

if you check out the ECMA docs on StreamWriter, it states for Close:

Description
  This method calls System.IO.StreamWriter.Flush, writing buffered data to the
  underlying stream. Following a call to System.IO.StreamWriter.Close, any
  operations on the current instance might raise exceptions. 

  [Note: This version of System.IO.StreamWriter.Close is equivalent to
  System.IO.StreamWriter.Dispose(true).This method overrides
  System.IO.Stream.Close.]


and for Dispose(bool):

Description
  When the disposing parameter is true, this method releases all resources held
  by any managed objects that this System.IO.StreamWriter references. This method
  invokes the Dispose() method of each referenced object.
