❔ Using compact switch syntax

Is it possible to set format_code = 1 for case _ using C#8.0 switch syntax?

// int format_code
string format_name = format_code switch
{
  0 => "Format8Bits",
  1 => "Format16Bits",
  2 => "ImaAdpcm",
  _ => "UNKNOWN (trying to interpret as Format16Bits)"
};

It's "switch expression", by the by, if you ever need to google it And no, no straightforward way to do that You could use a workaround like

var (formatName, code) = formatCode switch {
  0 => ("Format8Bits", formatCode),
  1 => ("Format16Bits", formatCode),
  2 => ("ImaAdpcm", formatCode),
  _ => ("UNKNOWN (trying to interpret as Format16Bits)", 1)
};
formatCode = code;

var (formatName, code) = formatCode switch {
  0 => ("Format8Bits", formatCode),
  1 => ("Format16Bits", formatCode),
  2 => ("ImaAdpcm", formatCode),
  _ => ("UNKNOWN (trying to interpret as Format16Bits)", 1)
};
formatCode = code;

I like that approach, will give it a go. Didn't know you could assign multiple values with a switch expression

It uses tuples and tuple deconstruction

REPL Result: Success

var tup = (67, "hello");
var (num, msg) = tup;

Console.WriteLine($"num: {num}, msg: {msg}");

var tup = (67, "hello");
var (num, msg) = tup;

Console.WriteLine($"num: {num}, msg: {msg}");

Console Output

num: 67, msg: hello

num: 67, msg: hello
