What is the C# equivalent of Java's InputStreamReader and BufferedReader

Question

I'm trying to convert these lines into C#, but I'm struggling. Mainly with InputStreamReader and BufferedReader lines.

private static void runPrompt() throws IOException {
    InputStreamReader input = new InputStreamReader(System.in);
    BufferedReader reader = new BufferedReader(input);

    for (;;) { 
      System.out.print("> ");
      String line = reader.readLine();
      if (line == null) break;
      run(line);
    }
}

private static void run(String source) {
    Scanner scanner = new Scanner(source);
    List<Token> tokens = scanner.scanTokens();

    // For now, just print the tokens.
    for (Token token : tokens) {
      System.out.println(token);
    }
}

The equivalent of an InputStreamReader in C# is a System.IO.StreamReader. There is - AFAIK - no direct equivalent to a BufferedReader in C#. There is BufferedStream, but that is for byte-oriented streams, not character-oriented. However, StreamReader itself can be configured with a buffer through one of its constructors (i.e. StreamReader(Stream, Encoding, Boolean, Int32).

Another way to look at it is that a C# StreamReader combines the functionality of Java's InputStreamReader (conversion from byte-oriented to character-oriented) and BufferedReader (buffering, reading lines).

I will be doing an byte-oriented system so BufferedStream should be thank you very much
