字幕修改的原理很简单，利用正则表达式，源代码如下

class Program
    {
        static void Main(string[] args)
        {
            using (StreamReader fs = new StreamReader("zimu.srt",Encoding.Default))
            {
                string data = fs.ReadToEnd();

                Regex regex=new Regex("\r\n[0-9][0-9]:[0-9][0-9]:[0-9][0-9].[0-9][0-9][0-9]");

                var matches = regex.Matches(data);

                int i = 1;

                foreach (Match match in matches)
                {
                    var oldValue = match.Groups["0"].Value;

                    var newValue = "\r\n" + i + oldValue;

                    i++;

                    data = data.Replace(oldValue, newValue);
                }

                Console.WriteLine(data);

                using (FileStream fs2 = new FileStream("newzimu.srt", FileMode.OpenOrCreate))
                {
                    byte[] bytes = Encoding.Default.GetBytes(data);

                    fs2.Write(bytes,0,bytes.Length);
                              }
            }
        }
    }
