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

Seen the Python answer like 3 times, but no Ruby?!?!?

the first part of the code declares a new array. Then you can just call the .join() method and pass the delimiter and it will return a string with the delimiter in the middle. I believe the join method calls the .to_s method on each item before it concatenates.

["ID", "Description", "Active"].join(",")
>> "ID, Description, Active"

this can be very useful when combining meta-programming with with database interaction.

does anyone know if c# has something similar to this syntax sugar?
