Adding string in front and at end of a list

Question

I have list of names:

IEnumerable<Name> names;
names = n.GetNames(abc);

It gets list like: Ken, John, Sam,... I want it to show like this: 'Ken', 'John', 'Sam',...

I tried this: string s = string.Join("',", names); but it gives result like: Ken', John', Sam',...

Is there a way to add "'" in front of these names in single line of code?

Try this.

string s = string.Join(",", names.Select(s => string.Format("'{0}'", s)).ToArray());

Your solution works great. Just missing ) and ToArray i updated it above. Thanks for the solution!

@NoviceMe that's because you run .NET < 4.0, with .NET 4.0 you can call string.Join with IEnumerable<string>...

@NoviceMe check the first parameter to Join.

I think you were almost there:

string s = "'" + string.Join("','", names) + "'";

This will fail however when names.Length == 0 ;p

Of all solutions, mine was the laziest! =D

Also, the most efficient as long as you add a check for the array length.
