Join a string using delimiters

Question

What is the best way to join a list of strings into a combined delimited string. I\'m mainly concerned about when to stop adding the delimiter. I\'ll use C# for my example

Answer 1

There's little reason to make it language-agnostic when some languages provide support for this in one line, e.g., Python's

",".join(sequence)

See the join documentation for more info.
