Adding chars before and after each word in a string

Question

Imagine we have a string as :

String mystring = "A,B,C,D";

I would like to add an apostrophe before and after each word in my string.Such as:

"'A','B','C','D'"

How can i achieve that?

Answer 1

What's your definition of a word? Anything between commas?

First get the words:

var words = mystring.Split(',');

Then add the apostrophes:

words = words.Select(w => String.Format("'{0}'", w));

And turn them back into one string:

var mynewstring = String.Join(",", words);

Answer 2

mystring = "'" + mystring.replace(",", "','") + "'";
