If it's going to be a large string, you may want to consider using the StringBuilder class because it is less memory intensive. It doesn't allocate memory each time you append another string, which yields performance improvements.

You can use String.Join:

List<int> myListOfInt = new List<int> { 1, 2, 3, 4 };

string result = string.Join<int>(", ", myListOfInt);

// result == "1, 2, 3, 4"
