Most efficent way of joining strings

I have a List. What would be the best possible way to create a single sting having all the strings in List but separated by ‘,’.

Thanks in advance

Answer 1

Probably:

var str = string.Join(",", yourList);

If you aren’t using .NET Framework 4, the overload for IEnumerable is missing so you need to convert it to an array first:

var str = string.Join(",", yourList.ToArray()); 

You can read more about string.Join at MSDN.
