StreamReader和StreamWriter在同一个Stream上？

Question

How do I manage closing StreamReader and StreamWriter which are using the same underlying stream?

var stream = /*...*/;
var reader = new StreamReader(stream);
var writer = new StreamWRiter(stream);

I know that I could simply ignore closing the reader/writer and just close the underlying stream. However, that seems a bit of a hack, since it is based on the assumption that the reader/writer doesn't have anything to dispose (which might not be the case in the future).

I know this have been solved in .NET 4.5 with an extra constructor argument, but until .NET 4.5 is released, how do I solve it in a proper way?

Answer 1

Make sure you Flush() the writer first.

And then just Dispose or Close the 2 decorators and the stream (nested usings are OK).
