这是我编的一个小程序，是要读取data.txt中开头是0的行，然后写进out.txt中，可是程序运行后，out.txt中是空的，求教是哪里错了呢？谢谢！

            string Line1 = "";

            StreamWriter radardata = new StreamWriter("E:\\out.txt", false);
            radardata.Write("译码：");

            while (Line1 != null)
            {
                Line1 = data.ReadLine();
