When you got a string array and you want turn into a string, you have two ways.

This way is useful if you work with every single string before convert.

string[] strings = { "hello", "world", "I", "am", "an", "array" };
string result = "";
foreach(string s in strings) {
result += s + " ";
}

This way is the best for performance and for best code.

string output = string.Join(" ", strings);

That's all folks!!!
