What version of the .NET framework are you using? The suggested String.Join() overload was added in .NET 4, before which the method only took an Array.Dan J– Dan J2012-11-17 00:50:23 +00:00Commented Nov 17, 2012 at 0:50

You can join your array using the following:
string.Join(",", Client);
Then you can output anyway you want. You can change the comma to what ever you want, a space, a pipe, or whatever.

You probably want something like this overload of String.Join:
String.Join<T> Method (String, IEnumerable<T>)

In your example, you'd use
String.Join("", Client);

You can write like this:
string[] arr = { "Miami", "Berlin", "Hamburg"};
string s = string.Join(" ", arr);

My suggestion:
using System.Linq;
string myStringOutput = String.Join(",", myArray.Select(p => p.ToString()).ToArray());

Your answer is functionally no different to the others.
string.Join<T>(String, IEnumerable<T>) already calls ToString() on the items, and there is a string.Join(String, IEnumerable<String>) method that doesn't need the ToArray().

Selecting the list element and converting to string avoids the ambiguity in different data types.
