Converting string to char[]

To convert a given string in char[] (character array), we use String.ToCharArray() method of String class, it is called with this string and returns a characters array, it converts characters of the string to an array of Unicode characters.

            //string variable
            string str = "Hello world!";

            //converting string to char[]
            char[] char_arr = str.ToCharArray();

            Console.WriteLine("str: " + str);

            //printing char[]
            foreach (char item in char_arr)
                Console.Write(item + " ");

            //printing types of string & char[]
            Console.WriteLine("Type of str: " + str.GetType());
            Console.WriteLine("Type of char_arr: " + char_arr.GetType());
