利用StreamReader解析歌词以及把读取的歌词写到新的txt文件里

//解析歌词
class Program
{

    static void Main(string[] args)
    {
        //i/o/ inputstream /outstream
        //目录是文件夹
        //带后缀的是文件
        //做一个字符流命名空间IO
       // StreamReader sr;//面向字符的输入流
       // StreamWriter sr1;//面向字符的输出流
       //1创建流对象
        StreamReader sr = new StreamReader(@"D:\C#1709\考试\shy\消愁.txt", Encoding.Default);
        //读取流
        string str;
        while ((str = sr.ReadLine())!=null)
        {
            Tast(str);
           // Console.WriteLine(str);//这是一行一行的输出
        }
        //3关流
        sr.Close();
        for (int i = 0; i < list.Count; i++)
        {
            Console.WriteLine(list[i].Time+" "+list[i].Lrc);
        }
    }
  static   List<Lrcs> list = new List<Lrcs>();
    static void Tast(string str)
    {

        string[] arr = str.Split(new String[] { "[", ".", ":","]" },StringSplitOptions.RemoveEmptyEntries);
        if (arr.Length==4)
        {
            Lrcs lc = new Lrcs();
            lc.Lrc = arr[arr.Length - 1];
            lc.Time = long.Parse(arr[0])+1000*60 + long.Parse(arr[1])*1000 + long.Parse(arr[2]);
            list.Add(lc);
        }

    }
}
class Lrcs
{
    string _lrc;
    long _time;

    public string Lrc
    {
        get
        {
            return _lrc;
        }

        set
        {
            _lrc = value;

    }

    public long Time
    {
        get
        {
            return _time;
        }

        set
        {
            _time = value;
        }
    }
}
//读取歌词并把读取到的歌词写到新的txt文件里
  //FileStream fs= File.OpenRead(@"D:\C#1709\考试\shy\消愁.txt");//打开
  //StreamReader s = new StreamReader(fs,Encoding.Default);//添加目录
        // string str= s.ReadLine();//读取
        //写出文件
        //FileStream fs1= File.OpenWrite(@"D:\C#1709\考试\shy\消愁1.txt");
        //StreamWriter s1 = new StreamWriter(fs1);
        //string str1;
        //while ((str1=s.ReadLine())!=null)
        //{
        //    s1.WriteLine(str1);
        //}
        ////最后的流先关闭，先建的流后关闭
        //fs.Close();
        //s.Close();
        //s1.Close();
        //fs1.Close();
