Solution in C# (judge verdict: Wrong Answer)

using System;

namespace ConsoleApplication{
    public class Program{
        public static void Main(string[] args){
            string searchWord;          //????´¢????±?????????????
            int wordCount = 0;
            searchWord = Console.ReadLine();
            searchWord = searchWord.ToUpper();

            while(true){
                string allWord = Console.ReadLine();
                allWord = allWord.ToUpper();

                //?????????????????´???????????????????????????
                if("END_OF_TEXT".Equals(allWord)){
                    break;
                }

                //???????????????????????????
                int wordLength = allWord.Length;
                int replaceLength = allWord.Replace(searchWord,searchWord + "A").Length;
                wordCount += replaceLength - wordLength;
            }

            Console.WriteLine(wordCount.ToString());
        }
