I have no idea what to do next for a vowel counter

Question

I'm stumped on why I'm getting 25 when I type in my name for the program. It's supposed to count the vowels and last time I checked chase only has 2. Here's a picture of assignment as well.

/* Program      :   Ch5Ex12a - CountVowels
 * Programmer   :   Chase Mitchell
 * Date         :   11/18/2015
 * Description  :   User's vowels are counted
 */
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Ch5Ex12a
{
    class Program
    {
        static void Main(string[] args)
        {
            int bacon=0;
            string Phrase;

            Console.WriteLine("Enter in letters");
            Phrase = Console.ReadLine();





                foreach (char a in Phrase)

                    bacon += 1;

                foreach (char e in Phrase)
                    bacon += 1;

                foreach (char i in Phrase)
                    bacon += 1;

                foreach (char o in Phrase)
                    bacon += 1;

                foreach (char u in Phrase)
                    bacon += 1;



            Console.WriteLine(bacon);
            Console.ReadKey();
        }
    }
}

foreach (char a in Phrase)
    bacon += 1;

What do you think this does? This does not iterate over all 'a' characters in Phrase. Instead, it iterates over all characters in Phase and counts them. It’s just that the variable name that gets assigned each character in each iteration is called a. But that has nothing to do with the content.

You tried to do something like this:

foreach (char c in Phrase)
{
    if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u')
        bacon += 1;
}

You should also check for upper-case characters; either explicitly or by converting the Phrase into lower-case first. You could do that by looping over Phrase.ToLower() instead of Phrase.
