How to convert an array of string to a sentence?

Question

How can I use Linq query methods to convert an array of string to a sentence?

private static void Main()
{
    string sentence = "C# is fun.";
    string[] words = sentence.Split();
    //string temp= words;       
}

The temp wants to have the same value as sentence.

Answer 1

You can use

var res = string.Join(" ", words);

or

string[] words = { "one", "two", "three" };
var res = words.Aggregate((current, next) => current + " " + next);

Answer 2

You can try:

var temp = words.Aggregate((x, y) => x + " " + y);

Answer 3

string temp = words.Aggregate((workingSentence, next) => 
      workingSentence + " " + next);

Answer 4

Use the String.Join method:

private static void Main()
{
    string sentence = "C# is fun.";
    string[] words = sentence.Split();

    // Join the words back together, with a " " in between each one.
    string temp = String.Join(" ", words);
}
