MemoryStream Class

• Provides an in-memory implementation of a Stream.
• Is meant for temporary streams.
  • Possibly to minimize the time you need to hold another stream open, e.g.: locking a file with FileStream.

• Remember to call Close on a stream.
  • Make sure to call them in the right order, and not too early. See the example below, where closing 'b' to early would close 'a' as well.

// MemoryStreams are usually temporary streams
// intended to be written to another stream later
MemoryStream a = new MemoryStream();
StreamWriter b = new StreamWriter(a);
 
b.WriteLine("Hello World");
b.WriteLine("Bye Bye!");
b.Flush();
 
FileStream c = File.Create(@"C:\Public\TestMem.txt");
a.WriteTo(c);
 
c.Close();
b.Close();
a.Close();
