Main problem for me is , in one file it is subscriber ID , other file it is mentioned as Member ID, How can i considered them as same , Can any one can help me with this. I am a intern developer, I don't have much experience on C#.

I tried this code but it is matching the pattern

    class Program
    {
        static void Main(string[] args)
        {
            string path = @"C:\Users\Kumar\Desktop\Insurance text\Previous.out.txt";
            StringBuilder buffer = new StringBuilder();
            using (StreamReader sr = new StreamReader(path))
            {
                while (sr.Peek() >= 0)
                {
                    String str = sr.ReadLine();
                    if (Regex.IsMatch(str, "Subscriber ID"))
                        buffer.Append(str + "\n");  
                }
            }
            Console.WriteLine(buffer.ToString());
             Console.ReadLine();
    }
}

in one file it is subscriber ID , other file it is mentioned as Member ID, How can i considered them as same

One would write a mapping function, but consider the data as just an id and then associate the data in the main program after reading in the entities , and storing both variables.

I am trying to extract data from .txt file. I need to extract Group Number,Subscriber Id,Name and Address (your network) from different .txt files.

You will need to write two different processes to extract the data. Using two different regular expressions for each one.
