Unexpected MemoryStream behavior

I am reading and writing to the same MemoryStream.

Something like this(possible compilation mistakes):

MemoryStream stream = new MemoryStream();
stream.Write("1234",0,4);
stream.Position -= 4;
stream.Read(buffer,0,4);

Why do I HAVE to move Position? Why it is not separate to read and write?

Is there any other Stream that can be used?

Because that's how streams are supposed to work. You have one position, see it as a cursor, set at a point in the stream at which you can read or write. Reading and writing both advance this position.

If you're merely using a MemoryStream to exchange data between callers, as a pseudo IPC mechanism, then perhaps some better way exists to do so.
