Creating a delimiter separated list from list of strings

When you have a list of strings like IList<string> of IEnumerable<string> and you want to convert it to for example a comma separated list you can easily do that with the String.Join method.

List<string> list = new List<string>() { "A" , "B", "C", "D", "E" };

string commaSeparated = String.Join(",", list.ToArray());

The output will be like this:

A,B,C,D,E

 

This is an easy and clean way to create a delimiter separeated list of strings.
