stream & streamreader

[andrewcw]

OK I am half way there - I can manipulate the stream
without the byte issue like this - but is this the way to
push the new values back into the stream & write out the
stream without resorting to byte conversion ??

FileStream stream = null;
stream = File.Open(fiPat h, FileMode.Open,
FileAccess.Read Write,FileShare .None);
System.IO.Strea mReader Tin = new System.IO.Strea mReader
(stream);
string existText = Tin.ReadToEnd() ;
fileContent=Rep lacementString
(oldStr,newStr, "","",existText );
// OK I HAVE MY NEW STRING...
System.IO.Strea mWriter Tout = new System.IO.Strea mWriter
(stream);
Tout.Write(file Content); // just sticks back in the stream
Tout.Close(); // IS THIS ACTUALLY UPDATING THE STREAM ??
Tin.Close();
// how do I persist the revised stream to file ??
stream.Close();

stream &amp; streamreader

OK By resetting the position of the stream before the
write and then resetting it again to check the stream
contents I find my updates in the stream, but how to get
them out simply to be written to the file ??

?? maybe I should post as new thread .... and reformulate
the question
