Can anyone expalin this method?

Question

public static string ReverseString(string s) {
char[] arr = s.ToCharArray();
Array.Reverse(arr);
return new string(arr);
}

Answer 1

* method takes a String
* char[] arr = s.toCharArray() creates a char array of your String
//"hello" --> ['h', 'e', 'l', 'l', 'o']
* Array.Reverse(arr) reverses this array
//['o', 'l', 'l', 'e', 'h']
* new String(arr) creates a String of your array (which is reversed now)
// ['o', 'l', 'l', 'e', 'h'] --> "olleh"
* method returns this string

Here is a description of the String class: https://www.google.de/amp/s/www.geeksforgeeks.org/c-sharp-string-class/amp/

Answer 3

Without new, it won't work. String is a class and with the keyword new you create an instance of this class (you create an object).
