Neat code to convert bool[] -> "false, true, true, false"

Question

How would you convert an array of booleans to a string like "false, true, true, false" - using as few lines of code as possible?

Python allows me to use the following (very nice and clean):

", ".join(map(str, [False, True, True, False]))

In C#, string.Join only allows me to join an array of strings.

So what is a short way to do the same in C#?

Answer 1

var array = new[] { true, false, false };
var result = string.Join(", ", array.Select(b => b.ToString()).ToArray());
Console.WriteLine(result);

Answer 2

How about:

String.Join(", ", new List<Boolean>() { true, false, false, true }.ConvertAll(x => x.ToString()).ToArray())

Answer 3

arrayOfBools.Select(x => x.ToString()).Aggregate((x, y) => x + ", " + y)

Answer 4

If you are using .NET 4, the following line is enough, because String.Join<T> internally calls the ToString()-method for every item.

Console.WriteLine(string.Join(", ", new[] { false, true, true, false }));
