C# how do I make string from array of string?

问题

Can you tell me an easy way to make a string from array of string?

I have:

String line = "how are you";
string[] split = line.Split(new Char[] { ' ' }); //{"how", "are", "you"}

How i can make back "String - How are you"? IT IS ONLY EXAMPLE, NOT REALITY :-) Thank you.

Use this:

string.Join(" ", split);
