using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.IO;
namespace search
{
    class Program
    {
        static void Main(string[] args)
        {
            string fName = @"D:\test.txt";
            StreamReader testTxt = new StreamReader(fName);
            string allRead = testTxt.ReadToEnd();
            testTxt.Close();
            string regMatch = "I am";
            if (Regex.IsMatch(allRead,regMatch))
            {
                Console.WriteLine("True:Found\n");

            }
            else
            {
                Console.WriteLine("False:Not found\n");
            }

            Console.ReadLine();
        }
    }
}
