How to join int[] to a character separated string in .NET?

Question

I have an array of integers:

int[] number = new int[] { 2,3,6,7 };

What is the easiest way of converting these into a single string where

Answer 1

Although the OP specified .NET 3.5, people wanting to do this in .NET 2.0 with C#2 can do this:

string.Join(",", Array.ConvertAll(ints, Convert.ToString));

I find there are a number of other cases where the use of the Convert.xxx functions is a neater alternative to a lambda, although in C#3 the lambda might help the type-inferencing.

A fairly compact C#3 version which works with .NET 2.0 is this:

string.Join(",", Array.ConvertAll(ints, item => item.ToString()))
