Hi Murugavelmsc,

You can write a method like below and call that method by sending your input string as parameter.

private static int findVowel(string str)

        {

            int count = 0;

            for (int i = 0; i < str.Length - 1; i++)

            {

                switch (str[i])

                {

                    case 'a': count++;

                        break;

                    case 'A': count++;

                        break;

                    case 'e': count++;

                        break;

                    case 'E': count++;

                        break;

                    case 'i': count++;

                        break;

                    case 'I': count++;

                        break;

                    case 'o': count++;

                        break;

                    case 'O': count++;

                        break;

                    case 'u': count++;

                        break;

                    case 'U': count++;

                        break;

                } 

            }  

            return count;
