I’m just curious about this. It strikes me that the behavior of a StringBuilder is functionally (if not technically) the same as a Stream — it’s a bin of data to which other data can be added.
Again, just curious.

Stream is an input and output of binary data.
StringBuilder is means of building up text data.
Beyond that, there’s the issue of state – a StringBuilder just has the current value, with no idea of ‘position’. It allows you to access and mutate data anywhere within it. A stream, on the other hand, is logically a potentially infinite stream of data, with a cursor somewhere in the middle to say where you’ve got to. You generally just read/write forwards, with Seek/Position to skip to a specific part of the data stream.
Try to imagine implementing the Stream API with StringBuilder… it just doesn’t fit. You could sort of do it, but you’d end up with StringReader and StringWriter, basically.
