读取二进制文件判断是否文件尾

public class ReadFile
    {
        public List<String> ReadType()
        {
            BinaryReader br = new BinaryReader(new FileStream("TypeInfo.dat", FileMode.Open, FileAccess.Read));
            List<String> node = new List<string>();

            byte[] farr = new byte[1024];
            const int rbuffer = 1024;
            while (br.Read(farr, 0, rbuffer) != 0)
            {
                string str = br.ReadString();
                node.Add(str);
            }

            br.Close();
            return node;
        }
