Get MessageSet IDs as a Comma-Separated String

Demonstrates the Chilkat MessageSet.ToCommaSeparatedStr method, which returns the unique identifiers as a comma-separated string in ascending numeric order. It takes no arguments; an empty set returns an empty string. This example inserts a few ids and prints them.

Background: This is the fully expanded, human-readable form — every identifier listed explicitly, such as 1,2,3,5. It is handy for logging or display. When you need the terse form that collapses consecutive runs into ranges (for example 1:3,5), use ToCompactString instead. Like the compact form, the returned string contains only the numeric values and not the HasUids setting.

void main() {

  // as a comma-separated string in ascending numeric order.  It takes no arguments.

  final msgSet = CkMessageSet();

  // Build a set by inserting individual identifiers.  The insertion order does not matter;
  // the identifiers are kept in ascending order and duplicates are ignored.
  msgSet.insertId(3);
  msgSet.insertId(1);
  msgSet.insertId(2);
  msgSet.insertId(5);

  // Get the identifiers as a comma-separated string.
  final csv = msgSet.toCommaSeparatedStr();
  print(csv);
  // Output: 1,2,3,5
