In C#: Add Quotes around string in a comma delimited list of strings

Question

This probably has a simple answer, but I must not have had enough coffee to figure it out on my own:

If I had a comma delimited string such as:

string li         


        

Answer 1

Here is a C# 6 solution using String Interpolation.

string newList = string.Join(",", list.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries)
                       .Select(x => $"'{x}'")
                       .ToList());

Or, if you prefer the C# 5 option with String.Format:

string newList = string.Join(",", list.Split(new char[] { ',' }, StringSplitOptions.RemoveEmptyEntries)
                       .Select(x => String.Format("'{0}'", x))
                       .ToList());

Using the StringSplitOptions will remove any empty values so you won't have any empty quotes, if that's something you're trying to avoid.
