How to store an array in a string?

Question

Example:

string x;
string[] y = {"5", "0","0","5","5"};
x = "50055"

I want to put it all together into one variable. I will store in a variable not print.

Answer 1

Only use the Join

    string[] y = {"5", "0","0","5","5"};
    string x = string.Join("",y);
    Console.WriteLine(x);

Answer 2

You can use the String.Join when you need a separator. So:

string[] nomes = {"Vinicius", "Rovann", "Anderson"};
return string.Join(";", nomes);
// Saída: "Vinicius;Rovann;Anderson"    

If you want to concatenate an array of strings into a single string, you can use String.Concat. Behold:

string[] arr = {"1", "2", "3"};
return string.Concat(arr);
// Saída: "123"
