MemoryStream Class

Overview

• Provides an in-memory implementation of a Stream.
• Meant for temporary streams.
  • For example, to minimize how long you hold another stream open, such as a FileStream that locks a file.

Good practice

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

Examples

Write to File

// 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();
